Aluminum Windows & Doors

Light yet strong, aluminum frame windows and patio doors can be configured into a wide variety of combinations. The narrowness of the frame places the focus on the glass and subsequently, the view it offers. Multi-panel glass walls are often made with aluminum frames to facilitate indoor/outdoor living. Capitol Door & Window aluminum frames are available in anodized or baked-on finishes for long lasting color. Sealed, mechanically joined corners stay square and true over years of use.

Because aluminum conducts heat and cold well, Capitol Door & Window offers a Thermally Improved Aluminum frame in select regions. Thermally Improved Aluminum windows and patio doors are equipped with thermal breaks to separate the interior and exterior surfaces and reduce heat transfer.
