Incredible Slimline uPVC Windows for Homes in Surrey

Most homeowners in Surrey and the surrounding areas don’t know that windows can account for up to 30% of a home’s heat loss. Here are Sheerwater Glass we know it’s worth choosing windows that perform well and looks good to make the most of your home.

Why might you choose Slimline uPVC windows?

Traditionally, the only slim frame windows on the market were aluminium, while standard uPVC always came with a noticeably thicker frame. We wanted to change that, so drawing on over 40 years of experience, we developed our own exclusive range of ultra-thin uPVC windows. They combine the performance you’d expect from a standard casement window with a much sleeker look, and a slimmer frame means more glass and more light in every room.

As a Sheerwater exclusive, our Slimline windows are also designed to complement the rest of our product range, so if you’re choosing a new door alongside your windows, you can be confident it’ll match perfectly for a consistent look across the whole house.
