Thermal barriers separate the interior and exterior of the aluminum frames, dramatically reducing the transfer of heat and cold. Double weatherstripping and deep interlocks stop wind and water leaks. Double-paned glass insulates and provides optimum energy efficiency. Optional Low-E coatings and Argon gas boost R-values even more.
Thermal windows are maintenance-free, made from strong, precision-engineered aluminum, with a durable powder coat finish that never needs painting. The tilt-in sash makes cleaning from inside your home quick and easy.
Strong cam locks and hidden locks provide exceptional security. Additional security is available with optional ThermalSafe glass.
Our Thermal Barrier aluminum windows feature a durable, maintenance-free powder coat finish in your choice of five Standard colors (below, left). Custom colors and anodized finishes (below, right) are available for an additional charge*.
