Maximum Heat Control for Winter

LoĒ-i89™ is our energy-saving 4th surface coated glass. It offers excellent visible light transmittance and low reflectance. Yet it delivers a center-of-glass U-factor of just 0.20 when coupled with our LoĒ³ or LoĒ² glass and argon fill in a 2-pane unit.

Even without argon and with or without capillary tubes, the unit still delivers a U-factor of just 0.23 – perfect for high altitudes.

Comfort in Any Kind of Weather

Who says you can’t do anything about the weather? Cardinal’s LoĒ²® coated glass delivers year-round comfort in any weather. In summer, it rejects the sun’s heat and damaging UV rays. In winter, it reflects heat back into the room.

Cardinal’s LoĒ²-272 offers a bit more light transmittance, while LoĒ²-270 gives a little more solar control.
