High quality products manufactured by us

All of our frames are made to measure and manufactured using steel-reinforced Kömmerling profile, which doesn’t contain any lead whatsoever. 

This means your windows won’t go yellow or discolour. If they do, it’s covered by your Unique Lifetime Warranty, and we’ll simply replace the frames.
