Why are UPVC windows popular?

UPVC windows are a reliable option that suits almost any home on the market.

UPVC windows became popular in the 1980’s and have remained a staple for UK homes ever since. This is thanks to their durability, low maintenance, and style. They made the perfect replacement for older timber windows, and since then, UPVC windows have been the go-to for replacement windows across the UK.

Our UPVC range is particularly popular with homeowners in Kent because of its versatility. For a modern home looking to replace their windows, our flush windows in anthracite grey can be the perfect choice. For a more traditional home, then our Georgian windows in a realistic wood grain could be the windows you’ve been searching for.

To see what makes our replacement windows an ever popular choice, we recommend speaking to our advisors who will give you a personalised quote tailored to you. To see our windows in person and experience them for yourself, visit our Gillingham showroom.
