Classic Series Cottage Style Windows for New Construction
Classic Series by Thermo-Tech Single-Hung and Double-Hung windows are now available in Cottage Style. Choose a larger bottom sash to retain the original architecture of your home on retrofit applications. Or use the larger bottom sash to keep the meeting rail from your line of sight in your lake home. These windows have the same great Thermo-Tech quality as our standard Single-Hung and Double-Hung units.
Please specify Thermo-Tech double-hung (TDH) or Thermo-Tech single-hung (TSH) when ordering. Grid configuration will change, depending on type of unit.
Our Standard LoĒ²™ 272/Argon Glass Is Anything But Standard
Thermo-Tech Classic Series Windows come standard with double-pane insulated LoĒ²™ 272/Argon glass featuring two panes of double-strength glass filled with argon gas for superior insulation. LoĒ²™ 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. LoĒ²™ 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 LoĒ²™ is nearly double that of an ordinary non-LoĒ™ insulated glass.
Available Glass Upgrades
High-Performance LoĒ³™ 366/Argon
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.
