Measures how well the window keeps heat from escaping. In Arizona, you want a low number, but the Solar Heat Gain Coefficient is even more critical.
Tempe’s environment is punishing. UV radiation that degrades vinyl and paint is no match for factory-baked powder coatings on aluminum. Aluminum frames will not warp in the 115°F heat, nor will they crack or become brittle over time like vinyl can. aluminum framed windows tempe, az
There is a trade-off. While a standard vinyl double-hung window might cost $400 to $600 installed, a quality thermally broken aluminum window can run $800 to $1,200 or more. Measures how well the window keeps heat from escaping
However, modern aluminum windows have solved this problem with . A thermal break is a structural barrier—usually made of polyamide—inserted between the interior and exterior parts of the aluminum frame. This significantly reduces thermal conductivity. UV radiation that degrades vinyl and paint is
However, aluminum is often more affordable than high-end fiberglass or wood. For homeowners planning to stay in Tempe for 20+ years, the lifecycle cost of aluminum (which may never need replacement) can beat cheaper vinyl (which may warp or require re-sealing after 15 years).
