Premier Steel Windows in Dallas

Windows serve many functions for a home or business. They bring light into the space, provide architectural interest, and offer protection from weather and excessive temperature fluctuations. At Portella, our custom windows are engineered and designed to give you the highest-quality, beautifully-crafted window without sacrificing any functionality.

While there are standard window sizes, specialized windows can come in a nearly unlimited number of size and shape configurations. Fortunately, Portella is able to offer customized steel windows based on your project’s specialized requirements. Thanks to our manufacturing facilities, we’re able to create almost any type of window from your exact specifications.

Custom Steel Windows Details

Portella’s custom steel windows provide both superior function and gorgeous aesthetics to your home or business. All of our custom steel windows are designed to elevate your design, while offering energy efficient and temperature resistant qualities to ensure a comfortable home or business for many years to come.

As with all Portella products, our custom steel windows are built with style and functionality at the core. We put our products through a rigorous testing and development cycle to ensure that every steel window we produce is of the highest quality. For example, NFRC rated, thermally broken, laser fusion welded, and cold-rolled options allow windows to maintain and control erratic temperature fluctuation. Maintaining a consistent temperature and not losing or gaining heat along the metal components also helps make our windows energy-efficient, which can reduce energy costs. Whatever your needs are for design and functionality, it’s our goal at Portella to give you the best custom steel window.
