Clement steel fenestration windows are made from only recycled steel producing the ultimate environmentally friendly window. At the end of their long life, 98% of the material can be recycled and steel requires very little energy to turn it from scrap into a reusable form once again.

The latest surface coating applied to steel window sections offer a life expectancy of at least 50 years. Steel as a material for windows is very sustainable, it has been known for Clement windows to outlast the properties they have been fitted into.

Steel has great natural resistance to weathering no matter what the climate and won't warp, rust or lose shape unlike other materials.
Perhaps the greatest advantage of steel is that as the metal is three times stronger than aluminium, the framing can be more slender and elegant allowing excellent solar gain….you won't have to turn the lights on so early…saving you money, and the planet's resources.
