When choosing the right windows and doors for your home, glass performance matters. At RAM Windows & Doors, we prioritize quality, energy efficiency, and comfort—which is why we use Cardinal LoĒ-366® glass in our products. This advanced low-emissivity (LoĒ) glass delivers exceptional performance, keeping your home cooler in the summer, warmer in the winter, and protected from harmful UV rays.
What Makes Cardinal LoĒ-366® Glass Stand Out?
Optimal Solar Control & High Visible Light Transmission
LoĒ-366® glass provides an ideal balance of allowing natural light in while reducing heat gain. This means your home stays bright without the added heat from the sun.
Energy Efficiency for Every Season
Designed to be placed on surface #2 of a double- or triple-pane unit, LoĒ-366® glass acts as a barrier against outdoor temperatures, helping to lower energy bills and maintain indoor comfort.
Blocks 95% of Harmful UV Rays
UV rays can cause fading and damage to flooring, furniture, and artwork. With LoĒ-366® glass, you get long-term protection against sun damage while still enjoying natural light.
Superior Insulation & Comfort
Unlike standard glass, LoĒ-366® minimizes heat transfer, keeping indoor temperatures stable and reducing the strain on HVAC systems.
Why It Matters for Your Home
Whether you’re building a modern home or upgrading existing windows, the right glass choice makes all the difference. With Cardinal LoĒ-366®, you get a year-round performance boost—cooler summers, warmer winters, and greater energy savings. At RAM Windows & Doors, we trust this glass technology to deliver the best in durability, clarity, and efficiency. Plus, with RAM’s 20-year warranty on glass, you can enjoy peace of mind for decades to come.
