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 districts. 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.
