Our Solution to Steel Window and Door Thermal Challenges

Steel door and window manufacturers often feature only insulated glass, failing to address the problem of thermal transfer to the metal frame. Portella’s Artisan Thermal Series, on the other hand, addresses all areas of thermal transfer, providing energy-efficient steel doors and windows that will stand up to the hottest Austin days.

This state-of-the-art series features GRP (glass reinforced polyetherimide), a non-conducting material with steel, that allows for both increased durability of the doors and windows and unprecedented thermal performance. 

Other manufacturers are also limited in their ability to customize their designs, which leaves them depending on European suppliers. Our new thermally broken profile patent allows us to fully customize our own designs and not have to depend on outside suppliers. As a result, we’re able to offer Austin customers steel windows and doors with the narrowest frames and sightlines on the market, perfect for Austin’s luxury residential, boutique commercial applications or historical projects.
