How to Prevent Condensation in Double-Glazed Windows

Posted March 11, 2025 by Mithul Mistry

Condensation in your home can be a worry as it’s a common cause of damp and mould, and it’s often noticeable on or in your windows. You’re probably wondering what’s causing condensation, how you can get rid of it and how to stop it coming back. We’ve covered all of this and more to help you understand what might be the cause and whether you may need to replace your double or triple glazed windows to resolve the problem.

What causes condensation on windows?

Condensation happens when warm or moist air comes into contact with cold glass or a cool surface. It isn’t uncommon, so many homeowners overlook it when it appears on their windows. Condensation can form on any colder surface, and we see it every day with droplets forming on mirrors, tiles and shower panels in your bathroom after a hot shower.

As winter approaches after a hot summer, our PVC windows and doors are more prone to becoming misshapen. This is because repeated exposure to quickly fluctuating temperatures can distort certain materials. Our windows and doors are exposed to more heat in the daytime and cooler autumn nights. This can expand and shrink the seals of double-glazed units, causing some damage to the quality of the seals which leads to condensation.

Why do my windows have condensation on the outside?

Condensation found on the outside of your windows is perfectly normal. It’s a sign that your double-glazed windows are highly thermally efficient as they are keeping the heat in and cold air out. This allows your home to maintain its temperature so you can stay comfortably warm and use less energy to heat your home. You’ll often find outer window condensation during the winter as the air is moist and the temperature drops.

Why do my windows have condensation on the inside?

Condensated windows inside the panes can be a cause for concern. It’s common to find condensation in your kitchen or bathroom, especially when cooking or taking a hot shower or bath. These activities release extra moisture into the air, increasing the overall humidity levels of these spaces. While some condensation is expected on cold surfaces, it’s still important to minimise potential moisture buildup in your home as repeated or constant condensation can lead to dampness and mould.

Indoor condensation isn’t limited to your kitchen or bathroom. Hanging up your washing indoors without using radiators, or hosting a large gathering of people, can cause steam to form on your windows too. You may even have excess condensation due to poor insulation in the roof or walls of your home.

What causes misted double glazing?

Condensation looks like a misted or cloudy window and can obscure your view outside whilst making your home look less appealing. If you notice you do have misted windows, this may mean your double glazing has ‘failed’.

1. Poorly fitted windows

If your windows were improperly installed, they’ll deteriorate quickly. In extreme cases, they could become cloudy in less than a year. When double glazing is fitted incorrectly, your window panes and frames won’t be aligned properly. This means your seals won’t last and gaps will form, allowing air and moisture into your panes.

2. Using the wrong products

You’d be surprised at how often double glazing can be damaged by human error alone. Many people use unnecessary harsh chemical products to clean their windows, which can reduce their effectiveness. A simple mixture of warm water and white vinegar is perfect to care for your windows and leave them sparkling for longer.

3. Damaged seals

Whether it’s poor installation or wear and tear, broken or faulty seals are one of the most common causes of cloudy and blown double glazing. Windows expand and contract when temperatures rise and fall. Although not visible to homeowners, this movement takes its toll on window seals, made worse by poor materials or shoddy craftsmanship.

Damaged seals allow moisture between the window panes, which is difficult to remove. Once inside, moisture causes condensation which means windows will become misted.

4. Window age

Time is another factor in the health of your double glazing. The date your double glazing was first installed impacts how well it will perform. Not only because the seals will become less effective over time, but also because modern fitting methods are more reliable.

How to prevent condensation in your windows

Condensation occurs in all homes and although it can lead to problems, there are initiatives you can take to help combat the effects. To stop or reduce condensation on double-glazed windows, there are a few things you can do to ventilate your home and reduce the risk of dampness and condensation.

Improve ventilation

By ensuring your home is properly ventilated, you’ll improve airflow and fight off issues caused by condensation. Opening windows and using vents or fans are all great ways to improve air circulation:

Promote better airflow by opening windows or doors on opposite sides of your house
Use exhaust fans in the bathroom and kitchen to extract humid air.
Allow air to flow into your home slowly, without inviting in a draught, with trickle vents

Heating & insulation

Condensation issues are intensified by sudden rises and drops in temperature as fluctuations cause water to evaporate and condense when you turn the heating on and off. Make sure your heating and insulation efforts are working hard to help you avoid condensation by:

Keep your heating at a constant low temperature
Ensuring your home has cavity wall and loft insulation
Checking your windows for draft, damp or steam

Clear moisture

An immediate solution to condensation is to remove any water droplets you come across in your home. In the short term, cleaning windows of condensation regularly can prevent moisture from developing into dampness or mould issues. Other things you can try to clear moisture in your home include:

Use dehumidifiers
Use condensation catchers
Avoid drying clothes indoors
Vent your tumble dryer properly

Common issues with condensation inside double-glazed windows

The place you should always be concerned about finding condensation is between the inner panes of double-glazed windows because it is a sealed unit. If condensation is appearing inside your double glazing, it’s often an indication that the seal around your windows has failed. Some other problems you might experience as a result of failed double glazing include:

With air entering the gap between the panes, the windows will no longer be as effective for thermal insulation.
Draughts can enter your home, cooling down your house. In colder months, you may see an increase in your energy bills as you try to combat the additional cold air.
Moisture getting in between the panes of glass ruins the aesthetic of your windows and leads to bigger problems like mould, dampness, heat loss and poor energy efficiency.

How to get rid of condensation between window panes

If you’ve noticed condensation between your double glazing panes and you’ve tried everything to combat it, it’s probably time to get your double glazing replaced so you don’t experience any further problems.

Everything You Need To Know About Double Glazing

Posted February 27, 2025 by Mithul Mistry

Double-glazed windows have progressed from a ‘nice-to-have’ to an essential feature in your home. From standard double glazing to bespoke styles, double-glazing can offer many benefits to both homes and businesses. In this article, we’ll cover everything you want to know from double-glazing history, right down to your commonly asked questions.

What is double glazing?

Double-glazed windows have two panes of glass, separated with a layer of normal air or, for more efficiency, a layer of argon gas. The panes are then sealed to keep the gas contained, creating an airtight, sealed unit.

A spacer bar maintains the gap between the panes and is usually made from aluminium or plastic with low heat conductivity properties. Energy-saving glass helps reduce heat loss but it can be more expensive to install.

How does double glazing work?

Double glazing is designed to slow the transfer of heat between the panes, keeping warm air in and cold air out. Air is a poor conductor of heat so trapping it between two glass panes means it is unable to circulate, leading to greatly reduced heat loss.

Over 20% of all heat loss escapes via your windows so by keeping warm air in, double-glazing improves your property insulation. This results in fewer draughts and cheaper heating bills as you may not need to heat your home as much as you would if you only had single-glazed windows.

Argon gas has around a 34% lower thermal conductivity level than air because it is denser so it acts as a better insulator. When it’s used between the panes it’s even harder for heat to escape through double-glazed windows, further improving thermal efficiency. It is also an excellent insulator of heat and is a non-flammable and ‘non-reactive’ gas. As a noble (or inert) gas, argon does not react in the presence of a flame or heat.

Energy-saving glass is even more efficient than standard double-glazing units with thermal spacer bars acting as a better insulator than standard aluminium bars.

The history of double glazing

After gaining popularity in the USA in the late 1940s, the UK began introducing double-glazed windows in the 1970s and 80s. Until then, window companies only produced single glazing.

Window specialists began using a ‘second window’ system in the mid-60s, which involved removing rotting timber windows and replacing the original window with a second layer of glass. Although this was a popular product for the time, aluminium double glazing was the next big breakthrough in the late 70s.

From the 1980s onwards, double glazing became standard for new UK homes. Although only about 8% of UK homes featured double glazing in the 70s, the concept quickly took off and now over 85% of homes in the UK are fitted with double-glazed windows.

Benefits of double glazing and low-E glass

Double glazing offers a range of benefits to your home, particularly around energy efficiency and keeping your family warm and comfortable. When combined with low-E glass, the benefits are only increased.

Keep your house comfortable

Low-E glass combined with double glazing can keep your house warm in the winter and cool in the summer. This keeps your home at a comfortable temperature year-round.

Reduce energy bills

The insulating effect of low-E glass and double glazing can reduce your energy bills each year. Preventing heat transfer through your windows, low-E coatings can reduce heat loss from the home by up to 50%.

Protect against UV rays

UV rays can damage homes and furniture, lead to peeling paint, cracked walls and a sun-bleached effect that makes furniture look faded. Low-E glass coatings reflect UV rays away from the home so it can limit the damage caused by UV light.

Keep condensation at bay

Low-E glass and double-glazing keeps the inside of the glass warmer, reducing the chance of condensation on the inside of your windows. Condensation can quickly spread and mould and dampness also pose health risks.

Less maintenance & upkeep

Low-E glass keeps windows, doors, and their surroundings safe from external weather conditions. The glass coating is also highly durable, and more resistant to scratches than standard glass alone.

More environmentally friendly

Energy-efficient glass and double-glazing is more eco-friendly because it requires less fuel to heat the home. It can be combined with other energy-efficient designs to reduce your carbon footprint on an even greater scale.

Benefits of double glazing for businesses

From a business perspective, double glazing offers many benefits from cost saving to improved security measures and works towards maintaining a comfortable working environment.

Improved security

Security concerns are one of the main issues for businesses so double glazing makes your premises much harder to break into and can deter thieves. The costs associated with upgrading to double glazing could negate any costs or losses if you were to experience a break-in.

Noise insulation

Double-glazing has soundproofing properties which is ideal for premises on busy high streets. The double-layered glass, alongside the soundproofing gases suspended in between, offers impressive noise reduction benefits. Double glazing is designed and fitted to enhance insulation, reducing noise by up to 70%.

Energy efficiency

Maximising energy efficiency efforts is essential within your business so double-glazed windows can help keep energy costs down. Double glazing works to regulate the temperatures inside your building, providing a natural balance of both cooling and insulating benefits, depending on the season.

Enhanced safety

Double glazing can help contain fire within a building or room. The double panes of glass, separated by argon gas, act as a barrier to slow the spread of damage to your business in the event of a fire.

Aesthetics

With quality double glazing, your windows should remain clear and condensation-free while reducing the risk of dampness and mould. This can improve energy efficiency and show you are up to date with improving sustainability as a business.

The best double-glazed windows

With so many types of windows to choose from, it can be confusing to know which style of double glazing is the best option for you. With this in mind, here are some of the most popular styles and the benefits they offer.

Double-glazed casement windows

As the most popular window style in the UK, casement windows are hard to beat. They are easy to use and open for maximum ventilation as the hinge mechanisms are smooth to operate. Some of the benefits of double-glazed casement windows include:

Easy to use
Enhanced security
Effective slanted design
A popular choice

Double-glazed bay windows

Bay windows are becoming an increasingly popular architectural revival feature of the modern home. With origins dating back to the medieval era and their use in churches and cathedrals, their popularity increased and they became a common feature within homes in the Victorian era. Double-glazed bay windows offer:

Architectural and aesthetic charm
Additional light
Expansion of the home

Double-glazed sash windows

Sash windows have been a popular feature within British architecture since the 17th century. They offer a traditional look, as the style became increasingly common during the Georgian and Victorian eras. With double-glazed sash windows, you can enjoy:

Traditional style and bespoke options
Great ventilation benefits

Of course, the ‘best’ double-glazed windows often comes down to personal choice. So, it’s worth considering your budget, style and the practicalities of your consent windows before you make a decision.

Double glazing FAQs

Can double-glazed windows be fitted from inside?

Yes, double-glazed windows can be fitted from inside, but if your frames are already fitted, it will depend on how the pane was fitted originally and what side the beading is on. When glazing any window pane into a frame, the glass panel needs to be held in place under compression, or with beading. With PVC windows, this is normally a plastic strip seen around the edges of the glass. This strip snaps the glass into place when you install double glazing, and only runs around the side of the window frame the glass was fitted from. If you can see the beading line inside your window frames, it means your glass was fitted from inside the home. If you see beading on the frames from outside the house, it means it was fitted externally. So, externally beaded frames need to be fitted from outside the home, while internally beaded frames need to be fitted from inside the home.

What is energy-efficient glass?

Energy-efficient glass is specially designed to reflect heat into the home, reducing the cost of energy bills. Instead of escaping through windows and doors, the reflected warm air is recirculated around the house. The most energy-efficient glass is called low emissivity, or ‘low-E’ glass. The emissivity of a glass refers to how well it can radiate heat energy. Normal glass has a relatively high emissivity rating, allowing 90% of thermal energy to escape through your windows and doors. Low-E glass features a microscopically thin coating applied to one side which is made from low-emissivity materials, like silver and other metallic oxides, that improve the thermal performance of the glass. These coatings are so thin and transparent that they don’t impact the amount of light that can enter the home – maintaining the original function of windows while keeping heat in. Double-glazed windows are often made with low-E glass, leading to more efficient fixtures that reap the benefits of both designs.

Who invented double glazing?

The exact origin of double glazing is often debated. Some believe it was created by American inventor C.D Haven in the 1930s but others claim it goes back as far as Victorian Scotland. As people used to rely on fires to keep warm, heat retention was notoriously difficult, especially in large houses. C.D Haven sought to fix this problem and invented an early version of double glazing called ‘thermopane’. Haven’s invention transformed homes across America and was widely adopted during the 40s and 50s before gaining popularity in the UK.

What does the future of double glazing look like?

There was once talk within the industry of triple glazing becoming the norm across the UK. However, it’s unlikely to take off anytime soon. Triple-glazed windows work the same way as double-glazing, with an extra pane of glass to create two hermetically sealed layers of gas. Although this does offer more insulation, it’s not a significant amount when compared to traditional double glazing. This means the minimal insulation gain isn’t enough to offset the much higher production costs. Triple glazing is popular in colder countries such as Norway and Sweden where homes benefit from greater insulation. In the UK, however, it’s unlikely that we’ll see an overhaul of traditional double glazing.

25 DIY Home Improvement Ideas

Posted February 19, 2025 by Ian Greenhalgh

Whether you’re tired of the decor in your house or need some low-cost ideas to make it feel more homely, we’ve got some home improvement DIY ideas to help you out. From free and simple fixes like clearing out to converting attic space and updating security systems, there’s plenty you can do to give your home the refresh it deserves.

Cheap home improvement hacks if you can’t afford to redecorate

Home modernisation doesn’t have to cost a fortune. In fact, there are lots of low-cost ways to improve your home without taking on huge renovation work, so start by giving it a deep clean.

1. Have a good old-fashioned clean-out

Set aside a weekend to declutter your home, tackling each room by deciding what to keep, donate, upcycle, or throw away. Letting go of unnecessary items will reduce stress and make cleaning quicker and more enjoyable. With less clutter, your home will be easier to maintain, giving you more time to relax and appreciate your space.

2. Clean up any paths or paving

Use a pressure washer to clean large areas and remove dirt and moss to quickly and easily improve your home’s exterior. In smaller spaces, a scrubbing brush with a specially formulated outdoor paving cleaner will help make the surface sparkling clean and prevent mould growth. Use weed killer on any plants growing up through paving cracks or dig them up by the root.

3. Tidy up greenery

A neat and tidy garden can be a lovely place to relax in the warmer months. Make sure to trim any shrubbery or bushes, mow long grass and pull weeds. Sure, you can hire a gardener — but with a pair of shears, some gardening gloves and determination, it’ll be much cheaper.

4. Clean the gutters

Over time, gutters can fill with debris like leaves, shingle granules, bird feathers and more, so it’s important to make sure that you regularly clean your gutters — once at the end of spring and once towards the end of autumn as a minimum. Once you’ve dislodged all of the debris from your gutters, use a garden hose to expel the remaining waste.

5. Get your glass gleaming

Ensure your windows are gleaming by giving them a proper clean. Clean windows look attractive outside and flood your home with natural light. A sponge and fairy cleaning liquid is the easiest way to clean the windows you can reach. For more effective cleaning on higher-up windows, professional tools will be able to get the job done and leave a sparkling finish.

6.Use walnuts to remove scratches on wooden furniture

An ingenious hack for those looking to freshen up their furniture. The natural oils of a walnut penetrate the wood and restore the blemishes so use the innards to gently remove marks and scratches.

7. Repair any annoying snags

How many times have you said you would get around to fixing that dripping tap or repairing the broken drawer? Getting these seemingly small repairs sorted can ease your mind of extra worry. If you have repairs that need an expert touch, such as cloudy or misty windows, or a toilet that’s flush isn’t as powerful as it used to be, there’s no harm in calling in the experts.

8. Try your hand at upcycling

Upcycling is a great way to put a creative spin on your home. Think about whether the furniture can be sanded down and painted, perhaps even add new knobs or handles, and maybe even think about utilising them as outdoor furniture. An old side table can make a great drinks holder for those summer barbecues, and bookcases can be used as planters.

9. Accessorise, if redecorating isn’t an option

Accessorising is a budget-friendly way to enhance your home’s charm without a full makeover. Simple additions like rugs can add colour and depth, fairy lights create a peaceful ambience, scatter cushions bring pops of colour and house plants can improve our wellbeing which makes a big difference.
Outside, potted plants, a fun doormat, or a small sculpture can boost curb appeal, while unique artwork from new artists can add personality to your walls without costing a fortune.

10. Paint your front door in a new colour

If you have a wooden door, a lick of paint can brighten up the space. Complement the style of the building with a colour that enhances the colour of the bricks. For a more coordinated look, match your garage door, front porch and gate.

For homes with uPVC doors, give your front door a new lease of life with a specialist cleaner to remove stubborn stains and improve wear and tear from weather damage.

11. Dress your windows properly

Updating worn window dressings can be a great way to refresh an old, outdated style. Light or natural-toned curtains let natural light shine through and have a chic appearance from the outside. You can also add some simple decor, like photo frames, ornaments, plants and flowers, onto your sills for a touch of warmth.

12. Update your hardware

Updating small items can lift a room and improve the look of your home from the outside. Using vintage knobs, such as ceramic, glass, or wood, can instantly transform an older piece of furniture. Meanwhile, a new door number, knocker or letter box can instantly update your home and reflect your personality.

13. Half paint walls to create height

Painting half your walls is cheap and creates the illusion of height which is perfect for those smaller rooms. Keep darker colours to the bottom of the walls and use a magnolia or white to blend in with the ceiling.

14. Add towel rails to your bathroom door

If you’re struggling for space in your bathroom or want to keep damp towels out of the way, install towel rails to the back of the door. This is a cost-effective and space-saving way to hang and dry towels, instead of fitting a heated towel rail.

15. Use felt pads on your furniture legs to stop scrapes

Simple, but effective. To preserve the life span of both your flooring and your furniture, use felt pads on the feet of your chairs or tables to stop any unnecessary damage.

16. Install shelves towards the top of your walls

Cupboards and bookcases can often take up unnecessary space, so why not fix sturdy shelving towards the top of your walls? This allows you to store books, without taking up floor space.

17. Use drawer organisers

Instead of bundling everything into a drawer, use dividers and organisers to separate your possessions. You will save on space and time because your items are easy to locate.

Home modernisation projects if you’ve got a bit more to spend

Sometimes a fresh coat of paint isn’t enough, so it might be time to take on a room or house renovation project. This could include anything from updating your security system to seeking planning permission and renovating entire rooms. Whatever it is, these DIY projects can bring a new lease of life to your home.

18. Change or upgrade your furniture

Once you’ve decluttered, you can have some fun with your home. Simply moving a side table or repositioning your sofa can change the whole look of a room while moving a lamp can add depth and size.

If you do have more budget, think about investing in fitted wardrobes. This can free up space you didn’t know you had, and provide more storage for those decluttered items. Choosing furniture with clean lines and minimalistic designs can also contribute to a more contemporary look.

19. Make eco-friendly upgrades

Curating an eco-friendly home is the first step towards modernisation. Replacing traditional light bulbs with energy-saving LED alternatives and opting for energy-efficient appliances can save money whilst reducing your carbon footprint. For bigger, eco-friendly changes to your home, effective insulation can make a more noticeable impact.

20. Choose ‘Smart’ appliances

Introduce a smart home system that integrates devices and appliances, allowing you to control them from your smartphone. Smart home appliances and apps can manage and optimise your home by setting timers around your daily routines. Automated lighting, heating, and security make everyday tasks seamless whilst conserving energy.

21. Let there be light

Create an illusion of space and breathe life into otherwise dull areas by ensuring your windows are clean and clutter-free. Consider installing larger Velux windows to allow more light in. Or, install fixtures that allow greater control over how much sunlight enters the home.

A light fixture by your front door adds extra security and gives your home a welcome glow in the evenings. Choose a design that complements your building. Classic, vintage styles look stunning on older properties, while more modern designs like solar lights or lanterns are a nice touch for newer homes.

22. Utilise your stairs effectively for storage

Staircases can take up a lot of space, but that doesn’t mean you can’t benefit from them. Install an under-stair cubby for coats and shoes, a modern under-stair storage solution to maximise space or even create a hideaway for reading.

23. Turn your garden shed into a practical space

Is your house getting too small for your family? Utilise garden space to create another room. Whether you want an outdoor office or a kids’ playroom, it’s a quick and easy way to produce more space.

24. Convert your attic into a guest room

Not so much of a hack, but converting your loft can create more space in your home without having to move. Adding an extra bedroom or chill-out area could even increase the price of your home.

25. Upgrade security

Enhance security by ensuring your windows and doors are stable before adding gadgets like motion sensor lights, video doorbells, and alarms. Robust external doors and double-glazed windows can protect against intruders and provide insulation. However, even double glazing isn’t foolproof, so regularly check for damaged seals, cracks, or weak spots, and ensure locks, handles, and hinges are in good condition to prevent easy tampering.

What is Triple Glazing, and is it Right for You?

Posted February 28, 2024 by Ian Greenhalgh

After the double glazing boom of the 1970s, double glazed windows quickly became a commonplace feature within modern homes. Today, it’s only natural that the homeowners that can afford to do so are looking to upgrade their windows beyond standard. The next logical step in upgrading from double glazing is to have triple glazed windows.

However, adding extra layers to your windows can only offer so many benefits. The performance of your windows also depends on climate. Rather than jumping straight in and investing in triple glazing without weighing up the pros and cons, this guide to whether triple glazing would work for you can help you decide.

What is Triple Glazing?

If you know what double glazing is already, the term ‘triple glazing’ speaks for itself. Triple glazing features an additional pane of glass alongside the two found within double glazed windows. This creates two gas-filled spaces within the window, rather than one.

Triple glazed windows can offer more insulating impact than double glazed windows can, since the amount of heat that can pass through the window is reduced with each additional layer of glass.

How Does it Compare to Double Glazing?

Cost

When considering the benefits of triple glazing vs. double glazing, cost becomes a significant factor. The cost of any window can vary drastically depending on frame material, size, treatments, and any additional features. The price of standard uPVC double glazed windows is relatively affordable, with the manufacture and installation of a classic casement window costing about £450 on average (as of April 2022). If we imagine an average semi-detached 3-bed home has 9 windows, this will come to £4,050 per home.

Investing in double glazing can end up being cost-effective in the long term. The energy efficient properties of A-rated double glazing windows can save homeowners up to £175 per year on their heating bills.

Taking into account the rising cost of fuel, triple glazed windows may be more cost effective than they once were. The average cost of a triple glazed window is around £550, so for a 9-window house this would be £4,950. Triple glazing is 20% more expensive than double glazing, but is it 20% more efficient?

Climate

The more energy efficient windows are in certain climates, the more money they will save homeowners. So, climate and cost go hand in hand when considering whether triple glazed windows are worth it. Those countries that have adopted triple glazed windows as standard are also more likely to have more affordable installation options. Scandinavia now uses triple glazing as standard, as consistently cold weather conditions justify the cost of installation and can save more money.

While it can help retain heat inside, triple glazing also blocks more sunlight and heat from entering the house. This can make your home feel noticeably darker and even chillier than it otherwise would on warmer days.

Security

Triple glazed windows naturally add an extra layer of security to your home than double glazed windows – though double glazed windows are already sufficient to stop most burglaries.

Sound Insulation

The most compelling benefit to installing triple glazing is the extra level of sound insulation it can offer. For those living in high traffic and built-up areas or main roads, that extra layer of sound protection can make all the difference. At a time when many people are working from home, it’s worth considering whether the sound insulating properties of triple glazing would ramp up your productivity levels in your office.

How Much Heat Can It Retain?

The U value of a window can be found on its energy label. Simply put, the u value explains how much heat can pass through a window with ease. The higher the U value, the more heat can escape your home through the windowpanes.

The U value of standard double glazing is ~1.4W/m²k. The U value of triple glazing is ~0.8W/m²k, so less heat can pass through a triple glazed window. Triple glazed windows therefore offer a 5% improvement in energy performance.

The energy performance of your windows alone doesn’t add up to all that much if you’re not investing in retaining heat in the rest of the house. If you are installing triple glazed windows, you might only noticeably benefit from their heat retaining impact if you subsequently insulate the rest of your home to such a high standard. This would incur more costs, further increasing the amount you’ll have to spend to see any returns on your investment.

Do I Need Triple Glazing?

Triple glazing has become a tempting upgrade for those who want to go all out on their property. For example, self-built homes are increasingly using triple glazed windows, as the option to install them from the beginning is there, with no replacement fees involved.

From an energy efficiency point of view, having all your double glazed windows replaced with triple glazed ones won’t make too much of a difference. Having single pane windows replaced with triple glazing is worth it, as triple glazing offers up to 50% more energy efficiency in comparison. In this scenario you could still opt for double glazing, which is almost as effective and quite a bit more affordable.

If tempted by the promise of extra comfort, you don’t have to have a whole house replaced with triple glazing. If you do opt for some triple glazed windows, you can choose to insulate only the rooms that would benefit you most.

What is Quadruple Glazing?

The innovations in double glazing don’t stop at three layers. Quadruple glazing – again, as its name suggests – features four layers of glass with three gas-filled gaps in between them.

The use of quadruple glazing is typically only found within very cold climates that remain at freezing temperatures or in the dark throughout most of the year. This is because the additional layer of glass and gas block the heat from sunlight from penetrating the window, as well as the cold. This can lead to those with quadruple glazing turning on the heating despite an otherwise warm day – reducing the energy efficiency of these windows for plenty of climates.

Windows with up to 6 panes are now available, though whether the benefits of using them will ever justify ever the cost is up for debate.

Verdict: Double Glazing vs. Triple Glazing

Considering climate, energy efficiency, and cost – double glazing remains the most efficient option for those living in the UK. They still allow the heat from sunlight to warm the home, while impressively reducing the loss of heat from within the home on cold winter days.

That’s not to say innovations in triple glazing won’t outshine its predecessor with time. US-based researchers at the Lawrence Berkeley National Laboratory developed what they called the “super window” back in 2018. Their design is a low-E triple glazed invention featuring a super-thin layer of glass as the third pane. They replaced the argon gas between the panes with highly insulating krypton.

It sounds just like a standard triple glazed window – however, these windows weigh almost the same, and are virtually the same dimensions, as their popular double-glazed counterparts in the US. This means only the windowpanes need to be replaced, while the frames can remain, cutting a significant portion from the cost of having triple glazed windows installed. When a great deal of the comparison between double glazing vs. triple glazing concentrates on cost, there is potential for further, more cost-efficient inventions to promote the uptake of triple glazing in the future.

Window Materials Guide: Wood, uPVC & Aluminium

Posted February 21, 2024 by Ian Greenhalgh

It might be time to upgrade your windows due general damages and wear or tear, or a lack of maintenance. Damp and mould in surrounding areas, cracked or broken glazing seals, and draughts within the home could be a sign your double glazing needs looking at. Replacing your windows can help cut down on your energy bills by ensuring effective insulation, while this can also stop the growth and spread of damp. If you’ve noticed your double glazing isn’t working like it used to, it’s worth discovering which other types of materials you can opt for while getting them replaced.

While aesthetics will undoubtedly play a key role when it comes to deciding which type of window material you will choose for your home, there are more factors to consider than looks alone. Whether you’re choosing between a traditional wooden frame or a sleek, modern aluminium look; it’s important to research the practical advantages and disadvantages of each window material before deciding which will work best for you.

In this guide to understanding the different types of window materials for double glazing, we’ll explore a few of the options available – and how they can benefit your home.

Wooden Windows

Wooden frames are a great choice if you are looking for a more authentic or traditional look throughout the home. They are also the best option when it comes to eco-friendly window materials. Timber production uses less fossil fuels in its manufacturing, significantly decreasing your carbon footprint in comparison with other options such as aluminium or steel. However, that’s not to say wooden windows are an easy choice – they may need more maintenance over time to remain in quality condition.

Timber for wooden frames can vary from softwood such as pine, to hardwoods such as oak. While these differences may seem minimal, your choice of timbers can influence the level of maintenance required, as well as the longevity of your frames.

Hardwood, for example, is better at withstanding damage as it is heavier and denser than softwood. For this reason, it is often more expensive; however, it’s a worthwhile investment for its strength and resilience. Softwood, on the other hand, is a lighter and less dense wood. This is because the material grows quicker, it cheaper to replace and install. Softwoods are also much easier to cut, so they’re a popular option due to ease of installation and manufacture. Despite being a lighter wood, softwoods can be a great insulator as a window frame, making them a reliable yet affordable choice.

It’s important to note that wood can change with the weather, expanding and contracting as humidity and temperatures fluctuate. To prevent warping, window frame wood used is often finished with a preservative that protects against weather and rotting from moisture damage – which are all risks that come with poorly maintained wooden frames. Oiling or waxing the wood regularly and examining for any damages can aid in preventing this.

Wooden frames are best suited to those who want to add a more authentic look to their home, or for those looking toward more eco-friendly options for their window frames. Don’t forget they do require a little extra maintenance, with regular oiling and careful cleaning recommended to maximise the longevity of the materials.

uPVC Windows

uPVC (Unplasticised Polyvinyl Chloride) is a synthetic plastic material, and is one of most common frame materials used in the UK. It’s cheaper and easier to install than other materials and is highly customisable, available in a range of colours and able to be shaped to fit the space it is being used in.

Unlike wooden frames, uPVC is incredibly easy to clean due to its plastic-based surface. uPVC is more durable with less maintenance, being unlikely to bend or rot in fluctuating weather conditions. Whilst longevity is not an issue with uPVC frames, they are not as easy to repair as other options. Minor scratches and dents are easy enough to fix, however larger damages may require a full replacement of the window in order to maintain waterproofing and the integrity of the seal. uPVC can also gradually become discoloured over time if the material becomes sun bleached. You may prefer a wooden or aluminium alternative if you prioritise the aesthetics of your home, or if you’re looking for a more unique or modern look.

Overall, uPVC is an ideal choice if you’re looking for low maintenance window materials that are cost effective and equally as insulative as your other options.

Aluminium Windows

Aluminium frames are ideal for the sleek and modern home. Both lightweight and strong, it offers extreme durability and efficiency which is only improved upon when you pair it with double glazing. Once thought to be a poor choice for insulation due to the threat of moisture build up within the frames, design improvements in modern aluminium framing and double glazing such as the insertion of a non-conductive material between the window panes has changed this.

This makes aluminium windows a great choice for maintaining a comfortable temperature in your home all year round. It’s also an excellent choice for the environment (and your wallet!) with enhanced insulation cutting down on your heating and therefore energy usage. While this makes aluminium frames a worthwhile investment in the long run, given the amount of money you would save on your household energy bills, the initial price of these frames can be quite costly in comparison to significantly cheaper uPVC or timber materials.

Despite their durability, these windows can fall victim to discoloration from the sun just like uPVC. This means the aluminium gradually grows darker depending on exposure to sunlight. However, if the sleek and slimline look is for you and you’re willing to spend now to save later; aluminium windows may be an ideal choice for your home.
