Standard Glass
Our Standard LoDz™ 272/Argon Glass Is Anything But Standard
Thermo-Tech Classic Series Windows come standard with double-pane insulated LoDz™ 272/Argon glass featuring two panes of double-strength glass filled with argon gas for superior insulation. LoDz™ 272/Argon blocks enough solar heat that cooling loads can be cut by 25% or more compared to ordinary low-E and clear glass. The·heat of the sun is composed of visible light and invisible infrared energy. LoDz™ 272/Argon allows the daylight to pass through the glass and filters out solar heat, blocking 84% of the sun’s harmful ultraviolet rays. Plus the insulating value of LoDz™ is nearly double that of an ordinary non-LoĒ™ insulated glass.
Available Glass Upgrades
High-Performance Lodz™ 366/Argon
Upgrade to Lodz™ 366/Argon heat-reflecting glass for even more insulating power and optimal thermal performance. Lodz™ 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, Lodz™ 366/Argon provides excellent fade protection, blocking 11% more ultra violet light than standard LoDz™ 272 glass.
- Lowers energy costs = saving on heating bill
- Blocks 95% of harmful UV rays = reduced fading on carpet, furniture, etc
- Year round comfort = cooler in summer, warmer in winter

- Performance
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.
