A Solution to Steel Window and Door Thermal Challenges
Portella’s Artisan Series is a solution for New York’s luxury residential, boutique commercial applications or historical projects. Our Artisan Series products have some of the industry’s best thermally broken profiles. Artisan utilizes a GRP (glass reinforced polyetherimide), a non-conducting material with steel, which combines strength and exceptional thermal performance.
Portella sets itself apart from other steel window and door manufacturers by offering only NFRC-rated, thermally broken, laser fusion-welded and cold-rolled option for your steel windows and doors. We invite you to navigate towards our Artisan product pages, where you may peruse through our design guide full of Artisan steel design window and door options.
