You should give careful consideration to windows that feature double pane glazing with double layered Low-E, Argon gas and Super Spacer.
Double Low-E glass is an excellent barrier against outside heat penetration, inside heat loss and ultraviolet rays which fade carpet, furniture, draperies, and even woodwork.
Argon gas is colorless, odorless, nonflammable, nontoxic, and above all, a safe, inert gas that is heavier than air which helps to increase the energy efficiency of a window. Argon gas also helps to make your home quieter as well.
Our windows meet or exceed the energy-saving requirements for all four climate zones set forth by the ENERGY STAR® Window program.
*Optional Triple pane glazing, double layered Low-E, double Krypton gas is available for superior efficiency.
