What is a Casement Window?

By far the most popular window chosen by homeowners because of the thin frames which gives you more glass and less uPVC. Casement Windows open outwards (away) from the building which stops the window fouling blinds and curtains when the window is opened. Upstairs casement windows are fitted with 'easy clean hinges' which allows for cleaning and fire escape purposes.

Benefits of a Casement Window.

The Casement Window is often chosen for its practicality, reliability and efficiency. Our casement window reflects radiator heat and and absorbs sunlight to create the most efficient A rated window. Replacing standard glazing with our 28mm low e glass units with warm edge spacer bar as standard will dampen outside noise significantly. Fully reinforced frames, internal beading, multi-pint locking systems and lockable handles complete the robust window which will give you full piece of mind.

Our Casement Windows are stylish, secure and hardwearing. Manufactured to BSI Kitemark Standards BS 7412 and BS 7412/PAS 24.Many of our high quality frames can be supplied with Secured By Design and Window Energy Rating (WER) standards.
