Planning a reno? ENERGY STAR® windows can cut your annual energy costs by up to 20% while keeping your home cooler in the summer and warmer in the winter.
What makes ENERGY STAR® windows so efficient:
The windows are double paned with an air- or gas-filled space in the middle, which insulate much better than a single pane of glass. If gas-filled, the insulating gas is odourless, colourless and non-toxic, like argon or krypton.
Special coatings reflect infrared light, keeping heat inside in winter and outside in summer.
A variety of durable, low-maintenance framing materials reduce heat transfer and help insulate better.
A spacer keeps a window's glass panes the correct distance apart. Non-metallic and metal/non-metal hybrid spacers also insulate pane edges, reducing heat transfer through the window.
If you're looking to upgrade or install energy-efficient windows, always look for the ENERGY STAR® symbol.
