Custom Windows Houston

Windows serve many functions for a home or business. They can bring light into your spaces, provide a wonderful aesthetic piece, and even help protect you from weather and excessive temperatures. At Portella, our custom windows are engineered and designed to give you a beautifully crafted window without sacrificing any of the functionality.

For many projects, the first thing you’ll want to consider are the size and shape of your windows. While there is a wide range of standard window sizes and shapes, there are times where some projects call for more detailed work. Fortunately, Portella is able to offer customized windows designed with particular projects and installations in mind. Thanks to our manufacturing facilities, we’re able to provide our clients with custom windows and designs tailored to their specific needs on any given project.

Custom Windows Details

As with all Portella products, our custom 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 window we produce is of the highest quality. All of our custom windows are designed to elevate your project, while offering energy efficient and temperature resistant qualities to ensure a comfortable home or business long after installation.


Our windows are focused on providing function as well as aesthetics. 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.

We currently manufacture four lines of custom metal windows:

  • Thermally broken – Thermal steel windows offer incredible durability and surpass all current energy efficiency requirements. We design your windows to last even when they’re up against the harshest climatic conditions.
  • Classic – The class style of custom windows is a perfect match for contemporary architecture, bearing sleek lines and minimalist profiles that invite a flood of natural light into your home.
  • Storefront exterior – The storefront exterior line of custom windows gives your storefront a unique steel window look with all the strength and durability needed to support commercial projects.
  • Storefront interior – For the storefront interior custom windows, you can create office and commercial spaces with a distinct, stylish look. With steel custom windows, the glass and steel are an ideal fit for the modern interior environment.
