About Us
Sustainability
Built sustainably, and to last.
Our windows and doors are made of sustainably harvested edge-grain larch and spruce grown in Austria’s alpine forests. We chose spruce for its strength and stable properties, and larch for its ability to withstand extreme cold and hot weather conditions. Our cladding is made from aluminum, a material that can be infinitely recycled. Together, these materials form a product that will last for generations: the true measure of sustainability. After all, why put all this energy into building something this good unless it is going to be around for a long time?
