Only BAYERWALD windows come with the original Tresorband, which was patented in 1999 and has been sold over a million times from that point of time on. This unique type of hinge is excelling in security and longevity while causing a flawless and elegant visual appearance of your windows.

The set in frame and therefore completely concealed Tresorband, which makes tilting and turning of the window possible, reliably stands up to even heavy load - as for example caused by energy saving multiple glazing. With its 70 mm rocket pin it makes the window being pried open almost impossible. Thanks to the concealed hinges, maintenance is very easy. An inbuilt opening angle limiter protects your reveal from damage.

With more than one million assembled Tresorbands, BAYERWALD windows already made history in matters of security and visual perfection. Benefit from our long experience and choose the original only!
