Our Solution to Austin 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, handles all areas of thermal transfer, providing energy-efficient steel doors and windows that will stand up to the hottest summer days in Austin, TX.

This state-of-the-art series features GRP (glass reinforced polyetherimide), a non-conducting material with steel. This design allows for increased durability of the doors and windows while providing 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 manufacture and fully customize our own steel windows and doors and not rely on outside suppliers. 

As a result, we’re able to offer Austin customers steel windows and doors with the sleekest frames and best sightlines on the market, perfect for Austin’s luxury residential, boutique commercial applications, or historical projects.

The Thermal Window Difference

Portella’s thermally broken steel windows with low e-glass are built with recycled material. Best of all, they’re designed to reduce the amount of energy needed for your home and keep it warmer in the winter and cooler in the summer.

With new windows, the heat in an occupied space must travel through the glass. But with thermally broken windows, the heat will be allowed to flow into your home from outside walls. 

Thermal windows also minimize sound bleedthrough by blocking soundwaves, which allows you to enjoy the room with next to no noise from outside.

Custom Steel Doors & Windows

What Sets Us Apart From Other Austin Window & Door Suppliers?

One of the best benefits of custom steel doors is that they keep energy costs low due to their insulation, protecting your space from extreme temperatures. Steel doors also reduce air condensation around windows and panels. 

In addition, steel doors require very little maintenance as they resist corrosion, are extremely durable and will last for years. If your Austin business needs to save time and money while still increasing the value of your building’s interior, then a custom steel door is a perfect choice.

Best of all, our custom steel doors in Austin are stylish and easily blend with modern designs. They’re available in a wide variety of colors to suit your individual taste or match your building’s theme. You’ll be able to create an open and welcoming atmosphere for customers without sacrificing privacy or security.
