All windows can have different glass options. Choose the LoE ultraviolet light protection that suits your needs. Double glazed sealed units or triple glazed sealed units are available for all styles. Every sealed unit is filled with argon gas and uses a triple sealed composite spacer for better insulating properties.
Double glazed windows have 2 panes of glass sealed together. We use an advanced triple sealed composite spacer in-between the panes for better insulating properties. The double glazed window is a very popular option and offers great efficiency. For additional safety and security the glass can be tempered or laminated.
Triple glazed windows have 3 panes of glass sealed together. We use an advanced triple sealed composite spacer in-between the panes for better insulating properties. The triple glazed window offers the best thermal break, with the best insulating properties. For additional safety and security the glass can be tempered or laminated.
Cardinal LoĒ-180 delivers outstanding cold weather performance – its insulation value is excellent with a low 0.26 U-Factor. And with an SHGC of 0.69, it lets the winter sun’s heat pass into the home. It also blocks 71 percent of the sun’s harmful UV rays. While blocking out the cold and UV rays, it lets the daylight stream in – more light than ordinary low-e glass.
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.
LoĒ³-366 is a clear coating that blocks even more solar gain, reflects heat, and lets the light stream in. It even outperforms the tinted glass often used in warm climates.
LoĒ³-366 provides exceptional fading protection. It blocks 95% of the sun’s damaging ultraviolet rays, protecting your furniture, carpets, curtains and wall coverings for years to come.
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.
