Performance
A Solution to Steel Window and Door Thermal Challenges
Other steel door and window manufacturers often feature only insulated glass, failing to address the problem of thermal transfer to the metal frame. We differentiate ourselves by addressing all areas of thermal transfer, providing energy-efficient steel doors and windows that will stand up to the hottest Houston days.
Other manufacturers are also limited in their ability to customize design. Our new thermally broken profile patent allows us to fully customize our own designs instead of depending on European suppliers. As a result, we’re able to offer Houston customers steel windows and doors with the narrowest frames and sightlines on the market.
Portella Difference
Since 1999, Portella has understood what architects want from steel doors and windows. Now, we’re proud to bring the Portella difference to Houston. Here are just a few ways Portella stands out:
With our thermally broken profile patent, we’re able to provide our trademark narrow-profile sightlines, something our competition just can’t do.
Factory-installed glass with Low-E options allows for maximum energy efficiency.
We provide NRFC-rated, thermally broken, laser fusion-welded and cold-rolled steel options.
Our designs are engineered and third-party tested.
Our wet-glazed glass glazing system eliminates moisture penetration, the perfect solution for Houston humidity.
One point communication with Portella project managers means you’ll always speak to a real person who understands you and your project.
