Victoria_BEWISOThe VICTORIA Window

We’re excited to introduce the newest addition to the 475 High Performance Building Supply product line: VICTORIA windows. We’re debuting this new, important addition at the NAPHN16 Conference. If you’re attending, please make sure to speak to us at the 475 booth, or contact us online for further details. This well-crafted fenestration comes to us from BEWISO (short for “BEst WIndow SOlution”). It’s manufactured in Austria by timber industry experts focused on offering the highest possible visual aesthetic, while maintaining Passive House levels of comfort and efficiency.

The VICTORIA window is Certified by the Passive House Institute, achieving Efficiency Class A for both the operable and fixed versions. Click the Certificate image below to download a full PDF. This is the only Passive House Certified simulated double-hung window available in North America. BEWISO_PHI_Certificate

The Historic Preservation Solution

The VICTORIA is Historic Preservation friendly, with extra narrow frames and mullions. Until now, it’s been a challenge to find a solution to the problem of fenestration for high performance retrofits located in Historic Preservation neighborhoods. Concerns regarding the aesthetics of windows from Historic Preservation Boards can hold up construction projects for months. The greenest building is the one that’s already there. Retrofitting our existing building stock is vital to decarbonizing our built environment. That’s why 475 has been dedicated to the concerns of Historic Masonry Retrofits, and Wood Frame Deep Energy Retrofits. As the only Passive House Certified simulated double-hung window available, VICTORIA allows you to more easily balance the insulation levels of retrofits projects – something retrofit specialists have had to struggle with in the past using models that were not quite there, thermally speaking.
