Welcome To Thermotech!
For most window companies, meeting Energy Star is the finish line.
Thermotech Fiberglass Fenestration is not like most window companies.
For Thermotech, Energy Star is the starting point. Nearly everything we build is triple glazed with insulation in the sashes and frames.
Most of our windows insulate 50% better and allow twice the passive solar gain of typical Energy Star windows. Our most energy efficient windows and doors routinely outperform European Passiv House windows.
Besides their maximum efficiency, our triple pane fiberglass windows appeal to an increasing number of discriminating buyers because of both their durability and their custom features. Features like hardwood interiors, custom sizing, divided lites and custom colors.
While we’ve always served the custom home market, both new and renovation, we are increasingly being specified in energy efficient commercial work.
