Warmcore Windows & Bi-Folding Doors

Warmcore Windows & Bi-Folding Doors

This new window and door system is designed to be as thermally efficient as possible, built around an innovative full width thermal core, with an aluminium outer frame, keeping your heat in your home yet not compromising on strength as the outer profile is made from high grade aluminium.

Strong and secure, Warmcore windows and doors are 25% more thermally efficient than traditional aluminium systems and come with multi-point locking, internal beading and a 10-year guarantee.

Available with a flush sash option that brings the frame perfectly level with the opening part of the window or door.


Casement Windows

Casement Windows

All our PVC-u casement windows are manufactured using the legend 70 profile system, so if you're looking for enduring quality coupled with the latest window technology, then this system offers everything you could ask for. Crafted from highly durable PVC-u, it offers an outstanding standard in energy efficiency.

Our windows can be glazed either externally with enhanced security clips and slimline looks or internally glazed. We offer a range of profile colours; white, light oak and rosewood and the artisan range. However, we can also spray your windows any RAL colour.
