Glass Options For Doors
High Performance LoDz 272/Argon
Double insulated glass with a dual coating of LoĒ on one glass surface
Thermo-Tech patio doors come standard with double-pane insulated LoDz 272 glass featuring two panes of double-strength glass with an argon gas filled airspace for superior insulation. This option improves heating efficiency by nearly doubling the insulating power over ordinary clear glass, and blocks enough solar heat that cooling loads can be cut by 25% or more. Fading of furniture, floors, and drapes is reduced by filtering out 84% of the Sun’s harmful ultraviolet rays.
Premium High Performance Lodz 366/Argon
Double insulated glass with a triple coating of LoĒ on one glass surface
Our double-pane insulated Lodz 366 heat-reflecting glass adds even more insulating power for premium thermal performance. Double-strength heat-reflecting glass with an argon filled airspace delivers a balance of solar control, thermal performance, and high visibility to optimize home energy savings and comfort. Plus, this option provides additional fade protection by blocking 95% of the Sun’s harmful ultraviolet rays.
Ultimate High Performance Lodz 366/Argon/i89
Double insulated glass with a triple coating of LoĒ on one glass surface, and one coating of i89 on the interior surface
Thermo-Tech’s Ultimate High Performance glass delivers a “twin punch”. It offers all the benefits of our Premium High Performance glass while maximizing thermal and visibility benefits, compared to other double-pane options, by adding a LoĒ i89 coating on the interior glass surface. Together this combination ensures the greatest thermal performance in all dual-pane applications. Blocks more than 95% of the Sun’s harmful ultraviolet rays.
Energy Guard Triple Insulated Glass Energy Star Most Efficient
Triple insulated glass with a triple coating of LoĒ on two glass surfaces
Get the maximum energy savings, comfort, ultraviolet protection, and the superior sound proofing of Thermo-Tech’s Energy Guard glass. Energy Guard doors incorporate three layers of double-strength glass with Lodz 366 on two glass surfaces, and two half-inch argon gas filled insulated air spaces. Designed for environments with high exposure to the Sun.
Energy Guard PLUS Triple Insulated Glass Energy Star Most Efficient
Triple insulated glass with a double coating of high performance LoĒ on two glass surface
Energy Guard PLUS triple-pane glass is specifically designed for tough Northern climates. Get maximum energy savings, comfort, ultraviolet protection, and sound proofing PLUS the added solar heat-gain necessary to optimize home heating during frigid Northern winter months. Energy Guard PLUS utilizes three layers of double-strength glass with LoDz 272 on two glass surfaces, and two half-inch argon gas filled insulated air spaces.
Super Guard Triple Insulated Glass Energy Star Most Efficient
Triple insulated glass with one coating of high performance LoĒ on two glass surfaces, and one coating of i89 on the interior surface
Super Guard triple-pane glass harnesses the Sun to help with heating your home. Ideal for climates with more heating days than cooliing days, especially in homes utilizing a passive solar design. Super Guard optimizes desirable radiant energy needed for solar heating applications, yet reflects radiant wavelengths when cooling the home during warm Summer months. Super Guard is composed of three layers of double-strength glass with LoĒ 180 on two glass surfaces, two half-inch argon gas filled insulated air spaces, and one coating of LoĒ i89 on the interior glass surface.
