Resistance® Glass Systems Performance Properties

Standard Insulating Glass Unit with clear glass, conventional aluminum spacer, and air fill Resistance® Glass System
Resistance® Glass System glass keeps you warmer in the winter

The overall U-Value (insulating value) of windows with Resistance® Glass Systems is about 39% better than standard clear insulating glass. (Lower U-values mean higher insulating performance.)

Resistance® Glass System glass keeps you cooler in the summer

Resistance® Glass System transmits about 48% less solar energy than standard clear insulating glass.* Solar Heat Gain Coefficient (SHGC) is a measure of how much solar heat is transmitted through the glass. (Lower numbers mean less summer heat.)

Resistance® Glass System reduces U.V. Energy and allows visible light transmittance

Resistance® Glass System is about 72% more effective at reducing fabric-fading ultraviolet (U.V.) energy, yet still allows about 88% as much visible light in as standard clear insulating glass.*

*Comparisons are based on center of glass measurements of 3/4″ insulating glass units; two 1/8″ (3mm) glass panes and a 1/2″ (12mm) air space. Actual glass performance may differ silghtly due to glass thickness, gas fill, and glass to frame ratio.

Resistance® Glass System Features and Benefits

Resistance® Glass System Features

• Improves window U-value as compared to standard glass.
• Allows the inner pane to stay warmer in winter.
• Reduces room side condensation of the window.
• Reduces the transmission of ultraviolet light.
• Has a natural appearance, both when viewed from the outside and inside.
• Carries a lifetime waranty against failure. We have sold more than 100 million sq. ft. of glasses since 1984 without a single documented failure.
• Created by a leader in flat glass manufacturing with extensive quality assurance and technical services groups and one of the worlds largest glass research and development centers.

Resistance® Glass System Benefits

• Customers save on both heating and cooling costs with energy efficient windows.
• Comfort is enhanced by reducing drafts around windows and allowing higher room humidity without condensation
• Builder callbacks and potential window deterioration due to excessive condensation are reduced.
• Fading of interior furnishings, such as carpets, drapes, and furniture may be reduced.
• The exterior of the home maintains a pleasing appearance and interior colors remain true.
• Customers can be assured that the glass in their windows is backed by the strength and experience of a leader in the glass industry and a Fortune 300 company.
• Customers enjoy outstanding technical support and access to the most advanced products in the window and door industry.
