    Tempered safety glass is standard with all Thermo-Tech Patio and Garden Doors. Tempered safety glass is extremely strong and often used for its safety characteristics. If tempered saftey glass does break, it breaks into small pellet-like pieces without sharp edges. Standard for patio door, tempered safety glass is also often the standard glass for side lights and even bathroom shower and tub enclosures. Tempered safety glass is ideal for reducing the likelihood of injury in the event of breakage.

    Choose our standard double-pane insulated LoĒ²™ 272/Argon glass or upgrade to LoĒ³™ 366/Argon heat-reflecting glass for even more insulating power and optimal thermal performance. LoĒ³™ 366/Argon heat-reflecting glass delivers the ideal balance of solar control, thermal performance, high visibility and the highest levels of energy saving in a double-pane insulated glass unit. Plus, LoĒ³™ 366/Argon provides excellent fade protection, blocking 11% more ultra violet light than standard LoĒ²™ 272 glass.

  • Energy and Structural Performance Data

    Thermo-Tech Premium Windows and Doors are thoroughly tested for structural and thermal performance according to the most widely recognized national standards, including the American Architectural Manufacturers Association (AAMA) window specifications. The numbers tell the story: every Thermo-Tech product is built for a lifetime of reliable, energy-saving performance.

    When you're shopping, compare structural and thermal performance ratings. Look for the performance grade (PG), which measures the window’s resistance to wind and rain. The higher the PG rating, the better. And check out the National Fenestration Rating Council (NFRC) label for an accurate method to evaluate a product’s energy performance and to ensure the windows are Energy Star® compliant in your area. Thermo-Tech windows are Energy Star® rated in both the U.S. and Canada.
