Strength, durability and longevity. Virtually maintenance free and energy efficient, aluminium combines strength and robustness with a lightweight structure – it’s extremely strong yet weighs 67% less than steel. This means that the frames won’t flex, warp or corrode in variable weather conditions, which is why it’s Concept Window’s material of choice for all our windows and doors in Dorset.

We’re established aluminium window specialists, meaning there’s no compromise on looks for safety with our windows. They are built with the highest grade stainless steel hinges, capable of carrying exceptionally heavy loads and beating every cycle test.
