Boulder, CO Historic Building Window Replacement

SolarGlass will be using a unique installation process for a project located at 1200 Pearl Street in downtown Boulder, CO. In order to maintain the Historic look of the building, yet improve the efficiency, a full frame window will be installed to the interior of the existing metal frame window.
The windows being used will be Marvin Ultimate Double Hung Magnum, Marvin Ultimate Glider, and Marvin Tilt-Turn windows with Low E 180 to maintain clarity.
