Frequently Asked Questions

What is a sash window?

Sash windows are vertically, or sometimes horizontally, opening windows consisting of two window sashes. Sash windows don’t operate on hinges. Instead, the window sashes sit in a frame with vertical grooves allowing them to slide up and down.

We offer modern UPVC sash windows that, in addition to sliding vertically, slide and tilt, allowing the sashes to tilt inwards to assist cleaning.

What are sash windows made of?

Sash windows used to be made exclusively of timber. Nowadays, a wider range of materials, including UPVC, aluminium and different types of woods, provide more possibilities.

The sash windows we offer are made of high quality UPVC. However, they perfectly match the look of timber sash windows, allowing you to match them to your existing timber windows. This way, you cannot only maintain the original style of your property, but also increase its security and thermal efficiency.

How long do UPVC windows last?

The lifespan of UPVC windows depends on many factors, such as the location of the property. On average, they last around 20-25 years.

All our products come with a ten-year insurance-backed guarantee (subject to T&C’s).

No. When our UPVC sash windows are coloured, stabilisers and modern extrusion techniques are used to prevent them from fading.
