The versatile Alitherm 300 is an absolute architectural classic, complimenting contemporary and traditional homes alike. In-keeping with the traditional appearance, dummy sashes are available to balance the sightlines on these windows to give a more symmetrical look and picture-perfect aesthetic.
The aluminium window profiles are built with a thermally broken aluminium frame and polyamide bridge, achieving outstanding energy performance. This design results in a higher standard of heat retention and guarantees a superior standard of energy management throughout. The improved energy means heating will be needed less frequently, therefore reducing heating costs and carbon footprint, simultaneously.
Enjoy lasting quality with aluminium windows. Highly durable, they will not rot, warp or discolour over time. Designed to meet the demands of today’s modern home, these windows are incredibly low maintenance. Aluminium is strong product that will withstand the worst of the British weather and keep your home safe and comfortable throughout the year.
