Triple-layer Coating of LoĒ³-366
Ultimate Performance Glass for Comfort, Efficiency & Visibility
LoĒ³-366 is a premium glass solution designed to deliver exceptional all-season performance through its advanced triple-layer low-emissivity (low-E) coating. Unlike standard window glass or traditional low-E products, LoĒ³-366 uses three layers of proprietary silver-based coating that work together to control heat transfer, block harmful rays, and maintain high levels of natural light — all while preserving a clear, attractive view.
How the Triple-Layer Coating Works
The three-layer low-E coating of LoĒ³-366 creates a spectrally selective surface that treats different portions of the solar spectrum independently:
Solar Heat Control: Rejects a significant portion of infrared heat, helping keep interiors cool on hot days.
Visible Light Transmittance: Lets in abundant natural light without the glare or darkening effects of tinted glass.
UV Protection: Blocks up to 95 % of damaging ultraviolet (UV) rays, protecting furnishings, flooring, and fabrics from fading.
This means you get a bright, comfortable living space with reduced reliance on cooling and heating systems — leading to energy savings year-round.
LoĒ³-366 glass is engineered for clarity and energy performance. It blocks nearly 75 % of solar heat energy while still allowing over 60 % of natural daylight to enter, helping reduce cooling costs and improving indoor comfort during the summer months.
Year-Round Comfort & Efficiency Benefits
Cooler Summers
The triple coating limits solar heat gain, lowering interior temperatures and stress on air conditioning systems.
Warmer Winters
Enhanced insulation properties help retain interior heat and improve surface glass temperatures on cold days.
Brighter Interiors
Maintains excellent visible light transmission even as it controls heat and UV penetration.
Energy Savings & Reduced Utility Costs
Lower heating and cooling loads often translate into reduced utility bills.
Protection from Fading
Solar control low-E coatings like LoĒ³-366 also block a high percentage of UV rays that can fade carpets, upholstery, and wood floors, protecting your interior finishes.
