Low-E Glass – Energy-Saving & Thermal Insulating Glass

Low-E Glass (Energy-Saving & Thermal Insulation)

Overview

Low-E (Low-Emissivity) glass is coated with a thin metallic layer that reflects infrared energy while allowing visible light. This reduces heat transfer, improves energy efficiency, and protects interiors from UV damage.

Key Features

  • Energy Efficiency: Reduces heating and cooling costs
  • UV Protection: Minimizes fading of furniture and fabrics
  • Thermal Comfort: Maintains stable indoor temperature
  • Visible Light Transmission: Maximizes natural daylight
  • Durability: Long-lasting coatings

Applications

  • Residential Windows and Doors
  • Commercial Office Buildings
  • High-Rise Curtain Walls
  • Hotels and Resorts
  • Schools and Public Buildings
