Single-silver low-E IGU glass features a special metallic coating that reflects infrared (heat) energy while allowing visible light to pass through. This helps to maintain a comfortable indoor temperature by reducing the need for additional heating or cooling. The term "single-silver" refers to the fact that the coating stack includes only one layer of silver.

Double silver low-E IGU glass is a high-performance energy-efficient glass that features two layers of silver film and an insulated design for superior thermal insulation and energy retention. The optimized configuration of the two silver layers effectively reflects heat and blocks UV rays, helping to maintain a stable indoor temperature, reduce energy consumption, and enhance comfort in both residential and work environments.

Triple silver low-E IGU glass is a high-performance energy-efficient glass that utilizes a triple silver film coating and an insulated design. With advanced coating technology and an airtight structure, this glass offers superior thermal insulation, soundproofing, and uv protection, making it one of the most energy-efficient glass solutions available in the market.
