Aluminium windows 25% more thermally efficient
Aluminium windows are available as a casement or tilt and turn.
Just like the aluminium bi-fold doors they are 25% more thermally efficient than the competition. Strong and secure, they come with multi-point locking and internal beading, and are backed by a 10-year product guarantee.
Each double-glazed unit has a u-value of 1.3 while the triple-glazed units are 0.8. Building regulations currently stipulate a u-value of 1.6.
Casement windows are available in a "flush sash" for ultimate clean, modern aesthetics.
Colour options are Pure White and Anthracite Grey. They can be supplied in different colours inside and out.
Non-standard colours available upon request.
Two external sash and outer frame designs: pencil round and square.
