High Performance Windows

The extreme contrast of hot summers and cold winters creates a need for windows to perform at the highest level of energy efficiency. At Alton Windows and Doors, we offer a variety of energy efficient window technologies such as standard clear insulating glass, argon-filled glass, warm edge and energy saving Low-E glass. We also offer double and triple glazed windows. All of these options combined will give you maximum energy efficiency.

Heat Transfer Resistance

U-factor measures the ability of a window to resist the transfer of heat and cold in winter and summer months. The U-factor of Alton windows exceeds the Energy Star guidelines for an energy efficient window. This resistance to heat loss combined with the welded corners of our frames and superior weather-stripping makes Alton windows one of the most energy efficient windows available for your home in Ontario.
