What Exactly Is Low-E Glass?
Low-E glass (short for “low emissivity”) uses a nearly invisible metallic coating to reflect heat energy. It keeps warmth inside during cold months and blocks excessive heat from entering during hot weather. The result? Year-round comfort and lower energy bills.
Despite the high-tech coating, Low-E glass remains crystal clear, allowing plenty of natural light to brighten your home while reducing glare.
How It Works
The Low-E coating reflects infrared light while allowing visible light to pass through. In winter, that means heat generated inside your home stays trapped indoors. In summer, the coating bounces solar heat away—reducing the need for air conditioning.
When combined with argon or krypton gas fills and multi-pane designs, Low-E windows can improve thermal performance by up to 40% compared to standard glass.
Benefits Beyond Energy Savings
- UV Protection: Blocks up to 95% of harmful UV rays that cause fading.
- Comfort: Reduces hot and cold spots near windows.
- Sustainability: Lowers your home’s carbon footprint by improving energy use.
- Noise Reduction: Multi-pane Low-E windows provide excellent sound insulation.
Different Types of Low-E Coatings
- Hard-Coat (Pyrolytic): More durable; ideal for cold climates.
- Soft-Coat (Sputtered): Offers superior insulation; better for year-round efficiency.
- Dual Low-E Layers: Maximum protection for homes in mixed climates.
