    Energy Efficient Coated Glass


    Cardinal LoE3-366® - Dual Pane

    Cardinal LoE3-366® glass is the ultimate performance glass that delivers the ideal balance of solar control and high visibility. Along with providing the highest levels of year-round comfort and energy savings, LoE3-366 provides exceptional fading protection as well. It blocks 95% of the sun's damaging ultraviolet rays (a leading cause of fading), so it will help your furniture, carpets, curtains and wall coverings stay beautiful for years to come.


    LoE3-340 - Dual Pane

    The solar performance of LoE3-340 glass is unprecedented in a double-pane unit - no room-darkening tint required with great glare control. Then when cold weather rolls around, its low U-Factor reduces indoor heat loss. Less heat gain when it's hot, less heat loss when it's cold, more comfort year-round, and the best glare control under the sun.


    LoE3-366® with LoE-180™- Triple Pane

    High performance triple pane glass is also available in the form of LoE3-366® with LoE-180™ included! Ask your sales representative for more information on this energy efficient combination!



    Adding LoE-i89 to windows already with LoE3-366®, or LoE3-340, takes your energy efficiency to the next level. Rather than absorbing internal heat, LoE-i89 reflects it back into the room, making your living space feel warmer and more comfortable. LoE-i89 provides triple pane performance from dual pane glass.


    Neat® - Naturally Clean Glass

    Neat®, naturally clean glass, harnesses the sun's UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless. This nearly invisible protection layer is applied to the exterior of your glass allowing your windows to stay cleaner longer.

    Obscure Glass

    Oftentimes used in bathrooms, mud rooms, and utility areas, specialty glass provides different levels of privacy while still allowing light into a room.

    PetScreen is tear and puncture-resistant to prevent damage by dogs and cats and is ideal for use in high-traffic areas. Additionally, PetScreen includes Microban antimicrobial product protection to stay clean longer and Water Shed TechnologyTM.
