    High Performance LoĒ² 272/Argon

    High Performance LoĒ² 272/Argon

    Double insulated glass with LoĒ² 272/Argon on one glass surface

    Thermo-Tech windows come standard with double-pane insulated LoĒ² 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. Thermo-Tech products utilizing this High Performance Glass meet Energy Star guidelines in casements, fixed casements, direct sets, and awnings.

    Our double-pane insulated LoĒ³ 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. Thermo-Tech products utilizing this Premium High Performance Glass meet Energy Star guidelines in casements, fixed casements, direct sets, and awnings.

    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. Thermo-Tech products utilizing this Ultimate High Performance Glass meet Energy Star guidelines in single hungs, double hungs, casements, fixed casements, direct sets, sliding windows, awnings, and patio doors.

    Other Glass Options

Standard for patio door, 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.
