Why You Should Choose Aluminum Windows by Milgard

Slim, durable, and light. Aluminum windows are perfect for homeowners looking for a surplus of style options with a sleek, modern design. Here at Lake Washington Windows & Doors, we can upgrade or replace your aluminum windows with our trusted partner Milgard Windows—a brand known for exceptional quality with national recognition. Want to know how aluminum windows can benefit your home? Explore our blog to know why having aluminum windows in your home is one of the best contemporary options.

Variety of Options with Aluminum Windows

Aluminum windows are popular for their wide array of combinations. Homeowners typically prefer aluminum windows due to the narrowness of the frames and the view it offers. Plus, the frames come in clear anodized (silver finish) or bronze anodized (black finish) to have long lasting color without fades. They are also available in a wide selection of operating styles as homeowners and architects love the overall modern design that can be achieved with aluminum windows.


Worried about the fragility? Aluminum windows are known for durability. The sealed mechanically joined corners are to stay in their square shape over a long period of use. Please note—we recommend that aluminum windows should not be installed in beach homes. Although made of water resistant material, the salt from the water and air can cause decay and corrosion, which affects overall frame performance and hardware operation.

Thermally Improved Aluminum

While aluminum windows are not as good against heat and cold conduction compared to fiberglass and wood frames, Milgard offers thermally improved aluminum windows in select regions. The thermal barriers in the aluminum frames allow for better insulation. By implementing this polyurethane barrier in between the frame, this creates a thermal bridge that helps reduce thermal flow through the frame.  As a result, the thermal break in thermally improved aluminum windows allows for better energy efficiency.
