U-Factor – measures how well a product can keep heat from escaping from the inside of a room (want low number)

VT (Visible Transmittance) – measures how well a product is designed to effectively light your home with daylight (higher number)

SHGC (Solar Heat Gain Coefficient) – measures how well a product can resist can resist unwanted heat gain (lower number)

R Value – measures the thermal efficiency, how effective the glass is for blocking air flow (higher number)

Air leakage – measures how much air will enter a room through a products. (low number <.3)

Solarban® 60 Solar Control Low-E Glass

"Solarban® 60 solar control, low-e glass by Vitro Architectural Glass (formerly PPG Glass) was engineered to control solar heat gain, which is essential to minimizing cooling costs.

With a very good Solar Heat Gain Coefficient (SHGC) of 0.39, Solarban® 60 glass blocks 66 percent of the total solar energy while allowing 70 percent of the visible light to pass through. This combination produces an excellent Light to Solar Gain (LSG) ratio of 1.79, along with exceptional insulating performance, as evidenced by its 0.29 winter nighttime U-value"

Quanex Super Spacer® Products

"Quanex’s Super Spacer® Standard, featuring polymer EPDM (Ethylene-propylene-diene-monomer) construction, dependably delivers high performance for insulating glass (IG) units, including excellent resistance to ozone, weathering, water and aging, while maintaining its flexibility through wide changes in temperature and barometric pressure. It’s an ideal spacer solution for residential IG construction.

Super Spacer is a pioneering technology that has set the standard for IG spacers for decades and has helped window and door manufacturers everywhere deliver outstanding performance with every unit."
