Low-Emissivity Glass

Product Introduction

Low-Emissivity Glass, commonly known as Low-E Glass, is a high-performance glass engineered to improve the energy efficiency and comfort of buildings. It is coated with an ultra-thin metallic layer that reflects infrared and ultraviolet rays while allowing visible light to pass through. This advanced coating significantly reduces heat transfer, keeping interiors cooler in summer and warmer in winter. Low-E Glass is widely used in modern architecture for residential, commercial, and industrial applications.

Product Features

Energy Efficiency: Reflects interior heat back into the room during winter and keeps out unwanted solar heat in summer.

UV Protection: Blocks up to 99% of harmful UV rays that can fade fabrics, flooring, and furnishings.

High Visible Light Transmission: Maintains natural lighting without compromising on thermal insulation.

Condensation Reduction: Helps prevent condensation buildup on the interior side of windows.

Multiple Coating Options: Available in hard-coat (pyrolytic) and soft-coat (sputtered) versions for different climates and applications.

FAQ

Q1: How does Low-E glass work?

A: Low-E glass has a thin, invisible metallic coating that reflects infrared energy (heat) while letting in natural light. It helps keep heat inside in winter and blocks it in summer.

Q2: Is Low-E glass clear or tinted?

A: It is typically clear but may have a slight tint depending on the coating type. It maintains high visibility and natural lighting.

Q3: Can Low-E glass be used in double-glazed units?

A: Yes, it is commonly used in insulated glass units (IGUs) for maximum energy efficiency.

Q4: Is Low-E glass more expensive than regular glass?

A: Yes, but the energy savings and long-term benefits usually offset the higher initial cost.

Q5: Can I use Low-E glass in hot or cold climates?

A: Absolutely. Different types of Low-E coatings are designed for specific climate needs – some reflect more heat, while others let more heat in during winter.
