uPVC Windows To Suit Your Home in East Grinstead

Whatever your design requirements might be, the Thermaframe team will help you find the perfect match. Explore the different styles available and get the inspiration you need.

Casement Windows

Casement windows communicate a neutral style that means they can be installed almost anywhere. We can fit them in your home, conservatory, orangery or house extension – the possibilities are almost endless with casement uPVC windows.

Side and vertically hung options can be explored when you speak to our team. Either way, you’ll be able to enjoy the benefits of a product that’s stylish and practical. If you want the European look, ask about our French uPVC casement window option.

Tilt and Turn Windows

Tilt and turn windows take the basic concept of a casement design, then add improved functionality. uPVC windows built in this style can be fully opened, but without making your home in East Grinstead unsafe – as its possible to open your double glazing inward.

Choose a tilt and turn design if you want a product that is easy to clean. When your uPVC windows are fully opened, the inner mechanisms will be fully accessible – so you’ll be able to ensure your double glazing looks brand new and performs to a high standard.

Sliding and Flush Sash

Our sash windows are beautiful and traditional! Our more traditional style sliding sash windows allows your windows to maintain its heritage charm, with the windows sliding horizontally upwards to allow an easy flow of cool air to enter your home. 

The newer style of flush sash windows, also known as flush casement windows, have the windows sit flush against the frame to create a contemporary and pristine finish to your windows. 

Bow and Bay Windows

Create a better sense of space in your home, conservatory or orangery with our bow and bay windows. If you prefer a more contoured edge, choose the curved design of a bow window; if straighter edges are more your thing, the modern lines of bay window will probably be more appealing.

When viewed from the outside, bow and bay windows add a three-dimensional effect. internally, they make a room feel larger. The alcoved area created by both these uPVC window styles can be used as an additional space for storing things or as a seating area.
