Everest Aluminium Casement Windows offer the following benefits...

More secure

More secure

Everest Aluminium Casement Windows come with a multi-point bi-directional steel locking mechanism which ensures they exceed British Standards for security. They are also internally beaded to ensure glass cannot be removed from outside.



The 20mm argon-filled gap within the double glazing panes, combined with a double rebated design and double draft-resistant seals keep more noise out.




The aluminium profile is insulated with a Polyamide core, designed specifically to prevent heat transfer through the frame and combined with a 20mm Argon-filled gap to minimise heat loss. Their low-E glass reflects more heat back into the room which helps to give them a B-rating for thermal performance.

More choice

More choice

They come in a range of colours with the option of choosing a dual colour where the windows can be specified white inside and black outside. There is also a wide range of glazing options, including leaded and decorative glass, and internal Georgian bars.

Less maintenance

Less maintenance

A naturally durable material, aluminium will never rot, rust, peel or flake. There is also the option of choosing self-cleaning glass too with our aluminium casement windows for even greater convenience.

Lifetime guarantee

Lifetime guarantee

There is a 25-year guarantee against discolouration on the aluminium profile and a lifetime guarantee against fog and condensation between the panes of the sealed unit. Everest Aluminium Casement Windows also come with a comprehensive 10 year guarantee on the whole window.
