Ask Louis: Why does condensation occur in the winter?

Condensation can be a reoccurring problem throughout the year, but is especially troublesome in winter. But why is this? We asked our resident window expert, Kirk Williams, to give us the low-down on the effects of colder weather and condensation.

condensation in winter


When temperatures drop, most of us utilise our central heating systems and fires a lot more than normal. This means that the humidity inside our homes is higher and condensation can occur more easily. As well as using these methods for heating, most of us are also tempted to keep windows and doors shut. However, this traps moisture inside.

During the summer, excess moisture from cooking, showering, and damp clothes drying doesn’t seem noticeable. This is because there are fewer cold surfaces for the humidity to gather and often we have our windows ajar, so it can escape more easily.

Cooler air also holds less water vapour than warmer air, which is why condensation seems excessive during the winter. Although it’s common to experience condensation during the winter, having a disproportionate amount could mean there are more serious problems afoot.  Damp patches, mould, peeling wallpaper, unpleasant smells, and water droplets on walls are all signs that your condensation problem could be getting out of hand.

Health problems can sometimes occur if excess condensation isn’t addressed in a timely manner, so it’s not just your home that could deteriorate, but your family’s well-being. If you have failed double glazing, this can contribute to an increase in condensation because the way in which the double glazing works is altered. In simple terms, double glazed glass prevents the movement of heat. You can read more about how double glazing works here.

By replacing any failed double glazing, you can prevent condensation from worsening, as well as improving your energy usage, which is important when energy prices are increasingly becoming higher and higher. The winter months mean most of us will be using the most energy we’ve used all year, so it’s important to do as much as possible to help save on these bills.

How to draught proof your home in time for Christmas

With the coldest day of the year recorded in November this year, it’s certainly time to start thinking about draught proofing your home for the coming winter months.

There are so many quick and easy ways to do this that will save you both time and money. We’ve listed some of the benefits of draught proofing below and how to achieve them without breaking the bank.


1. Windows

Windows are often the main cause of warm air escaping in the home; in fact, 20% of heat loss is attributed to windows, even when double glazed. Draughtproofing effectively can ensure that you save energy, especially during the winter months and the run up to Christmas. You can get this done professionally or buy products to fit yourself, such as self-adhesive foam, metal, or plastic strips.

However, you can ensure you don’t lose further heat from your home, and therefore increase energy bills, by having insulating glass installed and checking your units for any failed double glazing, so glass that may be clouded up or misty. In the long-run, this will help towards preventing against condensation and mould.

2. Doors

Again, doors are one of the main sources of heat loss in a home. Think about how many places there are for heat to escape – locks, keyholes, letterboxes, around the edges. Easy ways to help alleviate heat loss from your doors are to buy draught excluders, which you can pick up relatively cheaply; use a letterbox brush; and keep doors shut!

3. Attic

Your attic area can often be overlooked when thinking about draught exclusion. People often worry it will cost too much to sort out. A simple way to reduce some heat loss is by insulating the hatch with strips around the edges. Of course, you can insulate your loft fully, which is highly recommended, especially if you’re looking to save on your energy bills.


4. Pipework

Often overlooked, pipework can be a serious cause of draughts in the home, especially if you have a lot of exposed pipes. Using an appropriate material to fill in gaps, such as polyurethane foam or silicone filler will help to alleviate any problems moving forward.


5. Floorboards and skirting boards

Gaps in floorboards and skirting boards may seem like insignificant areas to think about, but along with all the above issues, they can contribute to the problem. Draught proofing skirting boards can be cheap and relatively straightforward, simply by using sealant along the edge.


draught proof your home


If you have suspended floors i.e. floorboards, then this is a potentially much bigger job to deal with. You may need to lift-up all of your floorboards up in order to gain access to lay insulating material, which can be a time-consuming and messy job. Although worthwhile in order to save energy in the long-run, it may be advisable to contact a professional in order to complete the job for you.

Ask Louis: The history of double glazing

history of double glazing


When was double glazing invented and who by?


Although there is no exact date on when the invention of double glazing came about or where it was initially used, but it seems that there is a good indication that it made an appearance within the late 18th century / early 19th century. A much cruder installation process back then, but it would have consisted of another sheet of glass being stuck to the original window, probably with putty.


When was double glazing first introduced into the UK?


As with many things, the US introduced modern double glazing to the masses first, in the early 1950s, with the UK following suit in the 1970s and 80s. Although window companies still existed before this, the emergence of double glazing didn’t arise until much later. From the 1980s onwards, double glazed windows were the standard for new UK homes, but even with this, to this day, there are still only 43% with full double glazing throughout the property.


How are double glazed windows made?


Double glazed windows are made by two separate panes of glass, which have a spacer bar in between them. This space is filled with either a gas or dehydrated air layer under vacuum conditions.


Why are they so effective?


The air or gas layer makes it extremely difficult for heat to escape, as it’s such a poor conductor. As I’ve mentioned before, over 20% of all heat loss escapes through your windows, so combatting this through double glazing (that’s in full working order) is effective and efficient.

However, when double glazing fails i.e. it becomes misted up or cloudy, it becomes ineffective and can cause an undue amount of problems, such as mould (because of excessive condensation) and loss of energy.

What is the future for double glazing?


Some within the industry have suggested that triple glazing may become the norm, but personally, I don’t think triple glazing will take off in this country, as our factories are all set up for double glazing and this would mean a complete overhaul in manufacturing.

We don’t have extreme cold temperatures like they do in places such as Scandinavia. On another note, the benefits are not good enough to warrant having triple glazing instead of double glazing because there isn’t a big enough change in UV Value. Triple glazing is expensive and does not give you much more than an A-rated energy efficient window.
