A Solution to Steel Window and Door Thermal Challenges
Artisan Series is a solution for luxury residential, boutique commercial applications or historical projects. Our Artisan Series is NOT a variation of existing non-thermally broken European extrusion products or “enhanced” thermally broken profiles. Portella’s Artisan specialty doors utilize a GRP (fiberglass reinforced polyetherimide) which is a non-conducting material with steel, that combines strength and superior thermal performance. Manufacturers offering only insulated glass without addressing the thermal transfer of the frame does to solve the problem. We invite you to view the Artisan design guide on our Artisan product pages.
