Quality Performance

Portella is proud of its products, but not just because they’re beautiful. Our steel and metal windows and doors are also dependable!

When you choose Portella products, you are choosing high quality craftsmanship and certified product development. Our doors and windows are not only third-party tested, but they also have ASTM, NFRC, AAMA, and Florida Building Code certifications. This allows us to ship and provide steel doors and windows for a variety of climates, weather conditions, and stringent building code requirements.

Thermal Challenges are a thing of the past

Luxury residences, boutique commercial storefronts, and historical projects deserve renovation solutions that are as unique as the property. Our Artisan series of steel doors and windows, storefront glass doors, and custom interior doors offer benefits that are both aesthetically pleasing and innovative.

If you’ve been searching for steel window and door options, but are worried about the product being unable to withstand the San Antonio heat, look no further.

Our Artisan Series is not simply a variation of the non-thermally broken European extrusion products or “enhanced” thermally broken profiles. Portella’s Artisan specialty doors utilize a GRP (Glass Reinforced Polyetherimide), which is a non-conducting material with steel, that combines strength and superior thermal performance. This science translates to your cool air staying cool, and your warm air staying warm.
