High-end commercial windows with Weather Shield will create a modern, environmentally friendly, and visually appealing look for your building. Our commercial windows are perfect for updating the look of restaurants, office buildings, retail establishments, apartment buildings, and more.

When you hire our team to design and install your commercial windows, you’ll enjoy many positive benefits that more than offset the installation cost, including:

  • Enhanced curb appeal: New windows offer a thriving ambiance that can effectively attract new customers and opportunities.
  • Improved energy efficiency & comfort: New, energy-efficient windows reduce drafts and minimize heat transfer. This will shrink your eco-footprint, lower energy bills, and improve the comfort of your employees and customers.
  • Reduced maintenance: Tilt-in sashes, self-cleaning glass, and other features reduce your annual window maintenance needs.


Commercial buildings in the DC metro area vary in shape and size, which means there’s no one-size-fits-all solution. Our customized window shapes and sizes allow you to select the ideal combination for your needs.

To achieve optimal results, we offer these types of windows:

  • Aluminum: Aluminum is the most popular commercial window option. It’s well-suited for curtain walls, storefronts, and more due to its durability and remarkable strength-to-weight ratio.
  • Fiberglass: Fiber-reinforced fiberglass windows feature a strong, thin, solid color frame that facilitates an unobstructed view of your commercial building’s exterior.
  • Vinyl: This popular, affordable window option is a cost-effective choice for apartment buildings, offices, retirement centers, and many other applications.
  • Wood: Wood windows help maintain your building’s historic appearance. Wood windows can be customized to perfectly match windows that were manufactured 50, 100, or even 200 years ago.
  • Wood-clad: Wood-clad windows give you the best of all worlds. These windows feature durable aluminum, fiberglass, or vinyl exteriors coupled with a warm, welcoming wood finish.

Window Styles

As important as the material selection is, style selection is vital to creating your desired appearance. We offer a variety of styles to suit your needs and goals:
