My Double Glazed Windows Are Misting Up Between The Panes
The weather has been especially beautiful recently, hasn’t it? Fabulous blue skies during the day and clear, starry nights. But in the Spring this type of weather means only one thing – the days are lovely and warm but the nights are chilly or even frosty.
The difference between daytime and night time temperatures mean heavy morning dews and more moisture in the atmosphere. It might mean you’ve noticed your double glazing is misting up between the panes or that the problem is getting worse.
Is the misting between the panes anything to worry about?
First of all, let’s look at the cause of the problem.
The two panes in a double glazed window are put together in a sealed unit. They are then inserted into the window frame. If there is misting between the panes, this means the seal in the unit has failed – in other words, broken. Units don’t break overnight – it’s a process that takes time. Seals don’t last forever, so the older a window is, the more likely it is that the seal will fail. If chemicals have been used to clean a window, this may damage the seal over time and cause it to fail.
It is worth saying at this stage that if you’re noticing condensation on the outside of your windows, this is nothing to worry about. It’s actually a sign that your windows are doing a good job – they’re keeping the cold out and the warmth in.
What should you do about misting between the panes?
Misting between the panes doesn’t mean you need new windows. It is perfectly possible to keep your existing frames and just replace the double glazed units. There are lots of companies that offer this service.
But it is worth asking yourself if this is a false economy.
Failed seals typically occur in older double glazed windows. Your windows may just have reached the end of their lifespan. Other things to look out for are cracks on the welds at the corners of your windows. You might start to notice draughts when you’re close to your windows or that it’s colder when you stand next to them.
Older generations of double glazed windows are also prone to condensation on the inside. It’s a sign that your windows aren’t as energy efficient as they could be. The warm, moist air inside your home is condensing on the cold windows. This is unsightly. It’s annoying to have to wipe down windows regularly to avoid mould and mildew building up. If you or any member of your family suffers from respiratory problems such as asthma, there are also health implications.
Manufacturing and technology have advanced dramatically in recent years. Today’s uPVC double glazed windows are more energy efficient and much more secure than previous generations.
For example, our uPVC double glazed windows have an A+14 Window Energy Rating, which means they are about as thermally efficient as it is possible to get. This thermal efficiency means it won’t cost as much to heat your home. It will also insulate your home from outside noise. If you live on a busy street or in a noisy area, this will make a big difference to your quality of life.
Our windows are also fitted with multi-point locking systems as standard and easily exceed BS7950 security specifications. Your home will be more secure and you’ll have greater peace of mind.
In short, misting between the panes of your double glazing doesn’t automatically mean you need new windows. But it might be something you need to start thinking about. If you’d like to discuss the options and understand the costs involved, give us a call.
