Why choose a uPVC casement window?

uPVC Casement Windows are virtually maintenance free, and will never flake, rust or rot. uPVC windows are made-to-measure and expertly installed for a millimetre tight fit, giving you a strong, secure and energy-efficient window. In fact, uPVC casement is our most thermally efficient window with triple glazing achieving a A++21 rating and our most secure window ever with the addition of GrabLock.

Why choose a timber casement window?

Our timber casement windows are precision crafted to perfection. Traditional framing options offer balanced sightlines and smoothweld technology, making the joints almost invisible. Micro-porous paint and stain finishes help keep your timber casement windows protected from the elements, so they look their best for years to come.

Why choose an aluminium casement window?

Aluminium casement adds a touch of style to any property, with our slimmest profile and a range of modern colours. The exquisite slim frame allows for a wider glass area to let the light flood in. Two-colour options add some style points with black on the outside and white on the inside, giving a lighter appearance in your home.

Traditional and contemporary window framing options available on Everest casement windows

Equal vs unequal sightlines

When choosing your framing options, it is important to consider the sightlines of the design. Sightlines are the horizontal and vertical edges of the glazing area. When the sightlines are equal it means that the edges of the glazing line up both horizontally and vertically.
