SL97 Composite Bi-Fold Door for Yorkshire Passive House Projects

For a bi-fold door that offers the natural warmth of wood, the strength and durability of aluminium, and the capabilities to reach passive standards, look no further than the SL97.

This gorgeous timber and aluminium profile system is specially designed with a 96mm panel depth combined with an additional layer of insulation and triple glazing - enabling it to reach overall U-values of under 0.8 W/m2 K.

And because it embodies the quality and German engineering that make Solarlux glazing systems so renowned, the custom made SL97 will add style and distinction to any passive home project.

A rare find

It’s rare to find an alu-clad timber bifolding door – and it's even harder to find one that meets passive standards. So the SL97 really is something special.

Add to that the fact that it's custom made to fit your space perfectly and reflects the innovation of a company that invented the original bi-fold door.

Balancing Form & Function

The SL97 composite bi-fold door offers you the best of both worlds for your passive home.

This alu-clad timber bi-folding door option combines interior wood and exterior aluminium to offer visual appeal alongside practicality.

Sustainable timber is used to achieve a softer appearance and cosier effect inside your home, while robust aluminium is durable and easy to maintain on the outside.

Your Bi-Folds, Your Choice

The SL97 is custom made to your unique requirements and aesthetic preferences. By choosing the SL97, you are unlocking the freedom to design your doors just the way you'd like them.

It offers a huge choice of RAL colours and wood finishes, as well as various door configurations with panels folding either inwards or outwards and sliding to either left or right.
