Frequently Asked Questions

What is a casement window?

A casement window is a window that is usually fixed to the frame through its side hinges and opens like a door. 

What is the difference between top-hung and side-hung casement windows?

Top-hung casement windows have hinges at the top but open at the bottom, which makes them ideal for ventilating a room without letting rain in. Side-hung windows are good at capturing passing breezes as they can be easily angled to direct fresh air into your home.

Is a casement window the same as a picture window?

A casement window swings open and allows lots of fresh air into your property. In contrast, a picture window cannot open and acts purely as a viewing point.

Are casement windows energy efficient?

Yes! When closed, a casement window is fully sealed as the sash presses against the frame and creates a protective seal. This prevents cold air from entering and heat from escaping, resulting in a warmer Exeter or Devon home that is less expensive to run.

If you want to increase the energy efficiency and noise reduction of your casement window, then we recommend double or triple glazing them. If you live in a very noisy area, we also have Stadip Silence window laminate for amazing noise-cancellation properties.

Are casement windows worth it?

We recommend getting them fitted. Imagine filling your home with more light and air. At the same time, the rooms in your Exeter or Devon property will be warm and cosy – thanks to the tight seal that blocks chilly air from entering.

How much are casement windows?

It is difficult to provide a price for your casement window as the material you choose, estimated fitting time, and other factors contribute to the overall costs. The best way to get a price is to call us at 01392 547272.
