In the UK, we long for sunshine most of the year. But in true Brit style when summer does finally arrive and temperatures soar, we’re not so happy when our homes can quickly become hot and stuffy.

Unfortunately, most UK houses aren’t built for hot weather, so when the temperature creeps up it’s important to take simple steps to improve airflow and keep your home cool.

If you’re wondering how to increase ventilation in your house, or whether to keep windows open or closed in summer, these tips will help you boost air circulation, reduce indoor heat, and create a more comfortable living environment.

1. Open and close your windows at the right time of day

The most common question in hot weather is: Should I keep my windows open or closed in summer? And the answer? Well, both. But it’s timing that’s key.

It may seem logical to crack your windows opening during the day when the sun is at its hottest. However, opening your windows lets hot air flood in, and actually makes your home even warmer.

Instead, keep your windows closed and curtains drawn to block out the heat. Then, once the outside temperature drops in the evening or early morning, open your windows to let cooler air flow in and refresh your space – perfect for making bedtime more bearable.

2. Use the chimney effect to boost air circulation

The chimney effect is a simple but effective way to improve ventilation in your home, and it’s been used in hot climates for centuries. This technique relies on the natural movement of air: cool air enters at a low point and pushes warm air up and out through higher openings.

How to create a chimney effect at home:

1. Open a window on the coolest, lowest side of your home.
2. Open another window on the hottest, highest side; ideally upstairs or near the ceiling.
3. Place a fan pointing outward in the upper window to help draw warm air out.

This creates a steady, natural flow of fresh air, which is just what you need on warm, still days.

3. Close curtains or blinds on south-facing windows

South-facing rooms get the most sunlight throughout the day. While this is great in winter, in the summer it can quickly turn into an uncomfortable problem.

Large south-facing windows and conservatories end up acting like greenhouses, trapping hot air inside.

To help reduce this effect you can:

• Close your curtains or blinds during the hottest part of the day.
• Invest in some blackout blinds or thermal-lined curtains for extra insulation.
• If you’re making home improvements, consider switching to solar control glass to help reflect additional heat.

4. Check your windows and doors for repairs

If your windows and doors are poorly sealed or stiff, it can unintentionally hinder airflow and make it difficult to properly ventilate your home.

If your windows don’t open fully, won’t stay open safely, or let in draughts during winter, it might be time for repairs. Fixing hinges, seals, or frames not only helps improve summer ventilation but also boosts insulation and energy efficiency year-round.

5. Make the most of trickle vents (if you have them)

Many modern windows include trickle vents; small openings at the top of the frame that allow a low level of fresh air into your home, even when the windows are closed.

These are a godsend in summer when you want a constant background airflow without fully opening windows (ideal for security or if you live on a noisy road). If your windows don’t have trickle vents, you could explore retrofit options or upgrades when the time comes to replace them.

Improving air circulation at home doesn’t need to be complicated. With the right techniques, from opening windows at the right time to using natural airflow methods like the chimney effect, you can reduce stuffiness, improve indoor air quality, and keep your home cooler throughout the summer months.

FAQs

Should I leave my windows open or closed during a heatwave?
Keep them closed during the hottest hours of the day to block warm air, and open them in the evening when it’s cooler outside.

How can I improve airflow in a house with poor ventilation?
Use the chimney effect, keep internal doors open, install extractor fans where needed, and make use of trickle vents.

What are the benefits of opening windows at home?
Opening windows helps reduce indoor humidity, expel stale air and pollutants, and bring in fresh air, especially when timed correctly.

The conservatory. It can be such a bright and peaceful spot to relax all year round. But, just like any part of your home, it needs a bit of love and attention now and again to keep it that way.

Nobody wants to deal with unexpected repair bills and regular care and maintenance goes a long way. Whether you spot mist between the glass panes, feel a sneaky draught, or wrest with a stiff door, it’s important to fix them ASAP.

In this guide, we’ll share some simple ways you can look after your conservatory.

1. Keep your glass panels clean and clear

It’s amazing how quickly dirt and grime can build up, especially on conservatory roofs and windows. To help maintain your double glazed windows, give your glass a gentle wash every few months. Warm, soapy water and a soft cloth are your best friends here. Just be sure to avoid harsh chemicals or abrasive pads that could damage the surface.

Top Tip: Clean on a cloudy day to avoid streaks from fast drying.

2. Look out for misted or blown glass units

Ever notice your conservatory windows looking foggy or misty between the panes, no matter how much you clean them? That’s usually a sign the seal on the double glazing has failed. It doesn’t just spoil your view; it means your conservatory isn’t as insulated as well as it should be.

The good news? In most cases, you don’t need a whole new window frame. Often, just the sealed glass unit itself can be replaced. It’s a simpler, cost-effective and less disruptive option.

3. Check for draughts, sticking windows or loose seals

Over time, conservatory windows can start to show signs of wear. Hinges might get stiff, rubber seals can become loose, and handles or locks might not work as smoothly as they used to. These might seem like small annoyances, but they can lead to draughts, let rain sneak in, or even make your home less secure if you leave them.

So, give your windows a regular check. Do they open and close okay? Are the seals looking healthy? If something isn’t right, it’s worth getting it looked at before it becomes a bigger issue.

4. Don’t forget about your conservatory doors

If you’ve got patio or French doors leading out from your conservatory, make sure they’re part of your check-up routine too! Warped frames, worn seals, or damaged glass on doors can also cause leaks and security worries.

Have a quick look: Are the doors hanging straight? Do the handles and locks work smoothly? Can you see any gaps or worn spots where draughts or damp could get in?

5. Manage moisture and prevent mould

Condensation can be a real pain in conservatories, especially when it’s colder outside. The key is good ventilation. Try to open windows or doors regularly to let the air circulate. If you continually try to prevent condensation, but it’s a persistent problem, a dehumidifier can really help. It’s also a good idea to leave blinds or curtains open when possible to help airflow around the glass.

6. Clean out gutters and check roof panels

Blocked gutters are bad news. If rainwater can’t drain away, it can overflow and potentially cause damp patches or leaks inside your conservatory. Make sure to clear out leaves, moss, and other debris regularly, especially after the autumn shedding season! While you’re at it, have a quick glance up at your roof panels for any obvious damage or cloudiness.

That’s where Cloudy2Clear can often help. They focus on fixing specific problems – like replacing just the failed double-glazed units, sorting out window and door hinges, handles, locks, and more. It’s all about helping you keep your conservatory in great shape without the stress or cost of replacing everything.

Double glazed windows are a sensible investment, adding extra comfort to your home alongside energy efficiency and security.

However, if you’re in the process of choosing which double glazed windows to buy, or deciding if you need a repair or replacement, it can be difficult to know where to start. With so many types of glass and frames to choose from, how do you know which ones are right for you?

We’ve broken down the different types of double glazing and things to consider before buying.

What is double glazing and how does it work?

Double glazing consists of two panes of glass that are separated by a layer of gas or air. The gap acts as insulation and reduces heat loss, noise and condensation inside your home.

Want to learn more about the benefits of double glazing? Check out our guide to double glazing benefits.

Types of double glazing glass

Let’s talk about the different glass options available to you when you buy double glazing. The type of glass you choose can impact many things, from energy efficiency to security and noise control.

Here’s an overview of the most common types of double glazing glass:

What to consider when buying double glazed windows

Buying the right double glazing is a big decision, and the best option for you will depend on your home’s needs, your lifestyle, and how much you’re willing to invest for long-term performance.

Below, we’ve broken down the key factors to help you make an informed decision.

1. Set your budget – but remember double glazing is an investment

The amount you spend on double glazing is influenced by many things:

• The size of your windows
• The style of windows you choose
• The type of glass you have
• The material of your window frames

It’s natural to select your windows so the price is as low as possible, particularly if you have a tight budget.

However, it’s best to think about the bigger picture and not rule out higher-spec options just to keep costs down in the short term. Higher-spec glass or frames are likely to bring longer-term benefits, such as keeping your house warmer in the winter and helping you to save on energy bills.

Of course, balancing long-term benefits and upfront costs is a balancing act. For a better understanding of price points, check out our guide to double glazing costs for average cost and repair options.

2. Prioritise energy efficiency windows and ask about energy ratings

Making your home more energy efficient is one of the biggest reasons people upgrade their windows. If energy efficiency is a top priority, it’s crucial to know what to look for.

In the UK, double glazed windows come with an energy rating label, just like fridges and washing machines do. These labels range from A++ (which is the most efficient rating) through to G. The higher the rating, the better your windows are at keeping the heat in and the cold out.

You should also know that if you’re getting new or replacement windows, UK Building Regulations stipulate that they must be at least a B rating or better, so check the rating before you buy.

Learn more about how energy efficient windows work and the benefits they have in your home.

3. Think about the security features of your windows

Your windows don’t just let in light, they also play a big part in keeping your home secure. Consider if the windows you’re buying come with built-in security features for that added peace of mind.

Most modern windows have multi-point locking systems. This secures the window at several points with one easy turn of the handle, making them much harder to force open than older single-lock designs.

Look to see if windows meet the recognised security standards. PAS 24 is the standard of testing that shows windows and doors have been tested for optimal break-in resistance.

4. Buy a window style that suits your home and surrounding area

Windows can influence curb appeal, so buying the right style of windows for your home is probably more important than you think, particularly if you’re considering selling your home in the future.

From modern casement windows to traditional sash designs, the right style will depend on your home’s character, the era it was built and your preferences.

Casement windows

Casement windows are a classic and practical choice that will suit most homes. Hinged at the side, they open outwards with a hinge mechanism. Simple and versatile, they are a popular choice for homeowners with both modern and traditional properties.

Sash windows

Sash windows are more of a traditional option for period or heritage properties. They slide up and down vertically and can be designed with a tilt-and-turn mechanism for better practicality. They are ideal for homeowners looking to preserve traditional aesthetics and benefit from the insulation and security of double glazing.

Tilt & turn windows

​​Tilt-and-turn windows are a popular choice for modern homes, flats, and properties where external window access is limited. They offer easy cleaning, flexible ventilation and enhanced security. Their inward-opening design also makes them a safe option for families with young children.

5. Buy the right window frame material

Alongside the type of double glazed windows you choose, you should also carefully consider the different frame materials available. Window frame material, much like window type, can influence aesthetics and curb appeal. In addition, window frames also impact performance (think energy efficiency, maintenance and longevity).

UPVC window frames

• Affordable, energy-efficient, and low maintenance; a popular all-rounder.

Aluminium window frames

• Sleek and strong, ideal for modern homes or large glass panes.

Timber window frames

• Natural and traditional in style, but needs more regular upkeep. Popular choice for heritage properties.

Replacing vs repairing: Know your options

If your current double glazing is misted, draughty or damaged, you may not need to replace the entire window. In many cases, you can simply replace the sealed glass unit, saving money, time and disruption.

We all like to think we live in a safe neighbourhood, but burglaries do happen. Some houses are targeted due to bad luck. Other times, criminals scope out homes beforehand and look for security weaknesses.

Ramping up your security measures might not make it 100% impossible to break in, but it can slow burglars down. With 25% of people claiming to be burgled, there’s no wonder we are searching for ways to protect our homes. Some of the best security measures don’t cost the earth – they simply involve learning new habits, while avoiding those that make your home an easy target.

Here’s our guide on how to protect your house and keep your family and belongings safe.

Keep valuables out of sight

Many burglaries happen due to perceived opportunity when a burglar thinks, or knows, there is something in your home that is worth stealing.

Increasing the privacy of your home can reduce your chance of being targeted. Hide valuables so they can’t be seen through windows or consider covering windows with privacy-enhancing screens or stickers. These are a popular choice for street-facing windows or if you don’t have a front garden, as they still let light in while the semi-opaque screen obscures the contents of your home.

Additionally, a car is likely the most expensive item you own, yet it’s often left out on display. Avoid parking your car in the street and park in your garage or on your driveway if you have one.

Keep the lights on

Burglars are looking for the easiest target. Most want to gain access as quickly and discreetly as possible, avoiding any additional or unexpected obstacles. They don’t want to break in to find a house full of people and risk being caught or hurt.

A classic trick is to make your home appear occupied when you’re out. Keep a couple of lights on or play music to make it seem like there’s somebody home. Additionally, try to make sure your gardens and any walkways are lit up at night with permanent or motion sensor lights. Burglars will likely choose the house in darkness over one that’s well-lit and exposed.

Check your locks and door handles

Security weaknesses can happen almost anywhere in and around the home. So, check your door and window locking mechanisms are in full working order every few months as they can wear down over time. In addition, padlocks and combination locks are a great option for securing sheds, gates, storage tubs, and gardening equipment.

Don’t just focus on the lock when looking for any faults – check the area around your locks too. If the windowpane around the handle feels weak, it’s easier for a burglar to break it entirely, rendering the lock useless. Easier still, simply make sure your doors and windows are locked when you leave the house and go to sleep and don’t fall into the 46% of people who fail to do so.

Single-point door locking systems

Front door locking mechanisms come with varying levels of security depending on the type of lock. From a single or double-cylinder lock, to a standard latch with a spring bolt and an additional dead bolt, there is a lot to consider.

From there, it comes down to what will make you feel secure, as there are several security options with these types of locks. These options include:

• Nightlatch
• Five-lever mortice deadlock
• British Standard BS 3621 deadlock
• Cylinder lock

Multi-point locking systems

For ultimate security, a multipoint locking system is the best. This involves a number of bolts and hooks around the frame, which are employed by lifting the handle. The two most common types are three-point and five-point systems.

Strong door handles

One of the weakest parts of the door and lock, the handle is where intruders are most likely to begin with their attempt to enter your home. There are a number of ways to exploit this weakness, so ensuring your handles are reinforced and in the best condition can help protect the door lock components from forced entry caused by picking or snapping.

Some features of a strong door handle include:

• Hardened metal body and bolts protect from simple wear and the brute force of potential intruders.
• Cylinder guards sit underneath the external handle and protect the cylinders of the lock from snapping if the handle is removed.
• Anti-drill rotating disk shield protects the barrel from being drilled.

Upgrade your windows for security

If you feel it’s time for an upgrade, getting your windows replaced is a great place to start improving your home security. But just how secure are UPVC windows?

There are hundreds of window combinations, each with its redeeming qualities. But there are three key things to consider when optimising your windows for security purposes and peace of mind.

Window design & frame

Casement windows are the most secure frame, since there’s no way to adjust the handle from outside. There’s also no way to force them open with a crowbar. You just need to make sure the window is closed and locked. Unable to enter by manipulating the frame, the only other option is to try to break the glass.

Double glazing

To strengthen the glass and deter burglars, make sure your windows are double glazed. Double glazing is as standard in new modern homes as it is insulating and can save you money on energy bills. There are many benefits to double glazing from a security perspective:

• Advancements in technology means that modern windows can increase security due to the added strength.
• Beading that holds the double glazing in place is fitted to the interior of the windows making it near impossible for the burglar to remove the glass from the outside.
• Durable double glazing is capable of withstanding a brick or stone thrown at it so burglars can’t make an entrance without drawing too much attention.

Type of glass

The type of glass in your double glazed windows makes a difference.

Tempered glass is specially heat-treated with intense heat then cooled quickly to resist more force. This action compresses the external surfaces of the glass, making the entire structure 4 times stronger than normal glass.

Reinforced glass is stronger than tempered or laminate, typically used in homes. The added strength helps deter break-ins and most reinforced glass doesn’t shatter into shards, making it safer if damage occurs.

Laminate glass is made of two or more pieces of glass bonded with plastic and is impact-resistant. It is often used in areas prone to natural disasters – such as coastal homes or homes on fault lines. The plastic allows it to remain within the frame, as opposed to shattering if it does break.

Doors provide the main entry points into your home. Composite and steel doors can offer the best protection against burglars but if your door is faulty, it’s almost useless so getting it repaired as soon as possible is crucial.

Think about a security system

While doors, windows and lights are excellent deterrents against potential thefts, there are additional security measures you can put in place to protect your home and family.

Security cameras

If you want 24/7 surveillance of your home, installing security cameras is a good idea. From simple doorbell cameras to a full CCTV system, there are plenty of options when it comes to home security. Not only do security cameras offer peace of mind but if they are visible outside your home, they can also act as a deterrent to potential intruders.

Alarm system

Just like security cameras, a visible alarm system can deter potential intruders from trying to enter your home. As well as that, if a burglar does gain entry, the sound of the alarm will alert you and your neighbours and, hopefully, startle them enough to leave before taking anything or causing damage.

Security locks

Security locks for UPVC windows add an extra layer of protection to prevent burglars from breaking into your home. Security locks fit most types of wooden and double glazed window frames and only allow the windows to open a small amount so it is difficult to break in through an open window.

There’s nothing worse than feeling a cold draught coming from your windows when you’re trying to get cosy on your sofa.

Not only does it cause you discomfort, it also leads to higher energy bills due to heat loss. And at a time when energy bills are more costly than ever, draughty windows are not ideal.

Draughts can be caused by damaged or faulty windows and will eventually need professional repair.

However, the good news is that there are steps you can take to draught-proof your windows, without spending too much money in the first instance.

How do you spot a draughty window?

• Look for visible signs of window damage

  • If you suspect your windows are letting in cold air, the first thing to do is check for any visible damage. Can you see any cracked window seals or gaps in the frame? Is there condensation forming between the glass panes?

• Do the candle test

  • Before you go lighting candles, make sure you move any flammable materials (like curtains!) out of harm’s way. Light your candle and then move it around the window frame. Does the flame flicker? You’ve found your window draught.

• Run your hand along the window edge

  • You can spot draughty windows by running your hand alongside the window edge. If you can feel cold air coming in, you’ve confirmed the problem.

Draught proofing windows: DIY tips & affordable fixes

Use self-adhesive draught excluder strips

Have you spotted small gaps around your window frames? A cost-effective way to prevent cold air from entering your home is by using draught excluder strips.

Draught excluder strips can be used to seal small gaps around your window frames by creating a tight seal.

They are relatively easy to install and can reduce heat loss without the need for specialist tools or expertise.

Different types of draught excluder strips

The right type of draught excluder strip will depend on the size of the gap and the material of your window:

Use window sealant to close gaps

Can you see small cracks or gaps around your window frame? Over time, small cracks can form where the window frame meets the wall, which lets cold air in – this is particularly common in older wooden window frames.

You may be able to seal the gaps around your window frames with high-quality window sealant. This can block draughts, prevent heat loss and also reduce moisture penetration to stop damp and rot.

Best overall choice: Silicone sealant

There are a variety of sealants available, but silicone sealant is the most versatile.

• It’s highly flexible – expands and contracts with window movement.
• It’s waterproof and weather-resistant – ideal for indoor and outdoor use.
• It’s long-lasting – lasts up to 20 years if applied correctly.
• Clear or coloured options – blends in with your window frames.

Where to apply window sealant

✔ Around the window frame: Small cracks between the frame and the wall can let cold air in.
✔ At window joints and corners: These are common weak points where air can escape.
✔ Along the exterior caulking: If the outside seal has deteriorated, draughts may be getting in from outside.

If you notice large gaps or crumbling window frames, a sealant may not be enough – your windows may need professional repair or resealing.

Use insulating window film for secondary glazing

Secondary glazing is a cost-effective alternative to double glazing, and is designed to add an extra layer of insulation to existing single-glazed or draughty windows.
It creates an air gap between the existing window and the secondary panel, trapping heat and preventing cold air from entering.
There are different ways of achieving secondary glazing.

While secondary glazing can help improve insulation, it’s not as effective as double glazing.

Thinking about upgrading your windows? Our guide on the benefits of double glazing explores how it can help long-term energy savings.

Invest in thermal curtains

You can reduce the draught from your windows without making any changes to the glass or the frames with thermal curtains.

Thermal curtains can be made from a variety of different materials such as cotton, polyester, and wool. However, what they all have in common is that they are thick and lined, helping to trap heat and keep cold air at bay.

Top Tip: Hang your thermal curtains closer to the window and make sure they fully cover the frame to make them as efficient as possible.

While thermal curtains go some way to regulate room temperature, they won’t solve the root cause of the cold draught from your windows.

Fix broken or worn window locks & handles

Are loose window locks or wonky handles causing draughty gaps in your window frame?

In some cases, tightening screws or replacing worn-out locking mechanisms is enough to tighten any broken seals and reduce cold air coming into your home.

• Loose or misaligned locks stop the window from sealing fully and leave small gaps where cold air can get in.
• Worn-out handles may not shut the window tightly enough, which reduces its efficiency in blocking out draughts.
• Damaged locking mechanisms can cause windows to shift slightly out of position, which impacts insulation.

Signs draught-proofing window hacks won’t see you through

If your windows still don’t close properly…

So, you’ve tightened screws, replaced locks and you can still feel a cold draught?

It may be time to call a professional. If your windows won’t close properly, even after DIY fixes, it could be down to misaligned hinges, or faulty locking mechanisms.

Not only is this bad news for energy efficiency, but it also poses a potential security risk.

If your window frame is rotting …

If your window frame is rotting, it’s a sign of serious moisture damage – and that needs urgent attention.

When water seeps into wooden window frames, the material begins to soften, weaken, and eventually decay.

Window frame rot puts the structural integrity of the window at risk and creates gaps where cold air can enter, which does nothing to help your energy bills.

If you can see cracks in the glass or condensation…

If you have cracks in your window glass or you can see condensation forming between double-glazed panes, draught-proofing hacks aren’t going to cut it.

Misted windows usually mean that the seal has failed, which allows moisture in and makes your home feel colder.

However, cracks or misting glass don’t mean you have to replace the entire window. An affordable alternative is to replace the failed double-glazing unit (and you can explore the cost-savings of window repairs in this guide).
