If your double glazed windows look like they’ve got a lot of condensation on them, you should take a closer look. If the moisture build-up is on the inside of the window, this is normal. Your glazing is likely to suffer with condensation when the outside temperature is cold and the inside temperature is warm.  Simply wipe away the excess moisture with a towel. If moisture is allowed to settle for a long time, black mould can grow. This can damage the window frame, leading to a reduced lifespan.

You should also ensure that air is able to circulate. Opening your windows for just a few minutes every day can solve a number of condensation issues.

However, if the condensation is occurring between the panes of glass, your double glazing is faulty and it’s time to get a replacement. 

Double glazing is built to last. A well-installed unit should last for between 20 and 35 years. In some cases they can last even longer. So long as you carry out routine maintenance and stay on top of any issues that occur, your double glazing should last for many years.

As well as this, choosing an expert installer like Classic PVC will ensure that the lifespan of your new windows is as long as it can possibly be. 

It’s true that aluminium is a more expensive material than uPVC. However, both offer many benefits.

If you’re looking for an affordable, long-lasting solution, uPVC is sure to fit the bill. It’s thermally efficient, won’t rot and comes in many attractive styles. The range of designs available in uPVC makes them ideal for listed buildings and modern homes alike.

Similarly, aluminium is also thermally efficient, rot-resistant and aesthetically pleasing. Aluminium is a lot more durable than uPVC, lasting for up to 50 years! Many people who prefer aluminium frames choose them for their durability. They’re usually seen in modern buildings, but come in a wide range of styles to suit many different homes.
