How do you prevent condensation in double glazing? You can do a few things to clear condensation away or stop it from developing. You can open your windows regularly to improve air circulation, use a hairdryer to clear away mist, or even repair your windows if you notice any signs of damage. Sometimes, though, condensation can take over a window.

Condensation occurs when the contrasting pressures of hot and cold air meet inside your home. While windows should stop this from happening, older designs aren’t as good at doing it. As a result, this collision can happen around your windows, creating a mist that builds on the inside pane. Worse still, it can develop into mould if left unchecked, and it increases the chance of your windows failing or breaking.

Some condensation is better than others. If you see a mist build up on the outside of your window, for example, it’s a sign your windows are performing well. However, if condensation develops inside your double glazing, you could have more trouble. If the mist builds between the glass panes, then the sealant may have broken through.

Once condensation gets into this area, known as the ‘air gap’, it’s only a matter of time until your double glazing fails. While you can reseal double glazed windows, the process can be complex and costly and may only give your windows a few months more of life. Due to this, replacing your windows with brand-new designs could be the best option. With advanced double glazing and durable profiles, condensation is much less likely to take control.

If you want to prevent condensation in your double glazing, the best way is to get new designs. And the best way to get new designs is to search through Double Glazing on the Web!

Causes and Effects of Condensation in Double Glazing

So, what causes condensation in your double glazing? Most of the time, the problem is the window itself. You might have old windows inside your home which aren’t air or water-tight. Wooden profiles, for instance, can bend out of shape and weaken over the years. High winds and heavy rain can damage them, causing gaps to emerge for cold air to enter your home.

When the air gets around your windows, it collides with the hot air inside your home. While double glazing can prevent condensation with the argon gas inside the air gap, it can’t do much when the air passes through in other ways. As a result, the frames start to lose their shape more, exposing the sealant in your windows to the elements.

When wind and rain contact the sealant, it weakens and begins to break. Once gaps begin to emerge inside the sealant, the collision of hot and cold air occurs inside the window. What that means is that the pressure the collision creates begins to strain the double glazing panels. Because of this, stress and pressure fractures are more likely, and they could internally shatter in extreme cases.

As condensation starts to develop inside your double glazing,  it can begin to fail quickly. Resealing the windows can help, but it doesn’t prevent the causes or the effects of condensation. Condensation can damage the whole window if you don’t clear it, and it could turn into black mould, a harmful substance that can cause breathing problems if inhaled.

Is Condensation Inside My Double Glazing?

If you have old windows, then condensation will most likely develop on them at some point. But, if it’s in the right areas, it doesn’t cause much damage. If you see mist build up outside your double glazing, it shows that the cold air from outside isn’t travelling far enough to get inside your home. All you have to do to clear it is use a hairdryer or give the window a good clean.

However, if condensation builds in your double glazing on the inside panel, that’s more worrying. When this happens, it shows that cold air is travelling into your living space far too easily. You can prevent this before it happens, though, by improving your home’s air circulation. You can either open the windows or invest in an extractor fan or dehumidifier to do this. Removing moisture sources such as plants can also help.

Where condensation is most harmful is inside your double glazing. Once mist builds inside the window panes, it proves that the sealant inside your windows has failed. Your sealant not only ensures that cold air stays out of your window but it keeps the argon gas inside. With no argon gas to level out the cold and hot air, they can collide without resistance.

While simple things like opening the window and using a hairdryer can work to clear other condensation, the only way to deal with condensation inside your double glazing panels is to either reseal the windows or replace them. But, while resealing is complicated and only provides a short-term fix, replacing your double glazing is a more long-term solution.

Preventing Condensation Inside Double Glazing

Preventing condensation inside your home is much easier with new double glazing. With a brand-new window, you’ll get a more durable design that works against the mist. Condensation usually builds because of gaps in your windows emerging over time or due to thin, flimsy materials. However, with advanced double glazing and robust profiles, you’ll protect your home for years to come.

One benefit of modern double glazing is that the whole design will be fully weatherproof. uPVC and aluminium are both weather-resistant materials, meaning that wind and water won’t cause lasting damage for decades. Your profiles won’t crack, twist or bend out of shape, meaning they’ll leave no room for cold air to pass around your windows and into your home.

Also, your double glazing will have less trouble in dealing with condensation. You’ll have two resilient glass panes which are thermally efficient, meaning they can prevent more cold air from travelling into your home. As a result, the collision between hot and cold air is much less likely to happen, meaning your windows are less likely to break as well.

Preventing condensation inside double glazing isn’t the only thing new windows can do, either. With a fully weatherproof design, your security hardware won’t rust or wear down, providing long-term protection from burglars. And, with a thermally efficient window in your home, you could save money on your energy bills throughout the year, even paying the cost of your investment back over time.
