Austin, Texas – January 8, 2019 – Portella, the leading manufacturer of thermally broken steel doors and windows is pleased to announce its new Thermally Broken Profile patent. As architects continue to seek doors and windows with narrower frames and sight lines, thermally broken profiles will become an increasingly popular option.  This doesn’t make sense. They want narrower frames and sight lines with superior energy performance values. This requires thermally broken.

“Our new system design has the narrowest sight lines of any steel D&W system available. This is the beauty of steel and what all architects want. Very narrow frames and sightlines while with superior energy performance. We have the ability to customize sight lines as small as 3/4″. Our new system is fully tested with NFRC ratings that exceed current code requirements”, says Portella owner, Marti Brunn.

The Portella Difference

Rather than purchasing profiles from European suppliers– as all other Steel W&D manufactures are doing, Portella’s new thermally broken system offers outstanding narrow sight lines. While other steel D&W manufacturers are restricted to offering only what is supplied by the European profile manufacturers, Portella has the capacity to customize frames and muntin bars to meet the most rigorous architectural designs.

Portella is also the only steel door and window manufacturer to use thermally bonded zinc galvanizing on each unit. While competing manufacturers offer this as a large upgrade for coastal environments, Portella offers this as a standard service on all products.

A Solution to Steel Window and Door Thermal Challenges

Portella’s Artisan Series is a solution for luxury residential, boutique commercial applications or historical projects. Artisan utilizes a GRP (glass reinforced polyetherimide) a non–conducting material with steel, combining strength and superior thermal performance.
