Passive House Certification for BEWISO

“Passive house construction is not about building in a cheap or ecological manner. It is about smart building and sustainable planning right from the outset”, explained Dr. Heinrich Bottermann, Secretary General of the German Federal Environment Foundation recently at the International Passive House Conference. Our contribution to sustainable building and renovation has successfully passed all mandatory examinations well in advance of the fair in Darmstadt: BEWISO has received the certification of the highest ph class A for its VICTORIA window model!

Simply beautiful!
In addition to this official recognition, the fair’s visitors have also taken great interest in our developments. They responded positively to the detailed processing of the wooden windows, to the sophisticated details that assure the product durability and high energy efficiency, and to the flexible application that is particularly suitable for the renovation of historical buildings. Many experts summarized their overall impression in one short phrase: “Simply beautiful!”
