Introduction
Insulated Glass Units (IGUs), also known as double glazing, are a key solution for improving energy efficiency, reducing noise, and enhancing comfort in modern architecture. At China Dowin Glass Tech Co., Ltd., we manufacture IGCC-certified insulated glass units tailored for residential, commercial, and industrial applications.
What is an Insulated Glass Unit?
An Insulated Glass Unit consists of two or more panes of glass separated by a spacer and sealed to create an air or gas-filled cavity. This structure significantly improves thermal insulation compared to single-pane glass.
Types of IGU
1. Standard Double Glazing
Two panes of clear glass with an air gap for improved insulation.
2. Low-E Coated IGU
Includes a low-emissivity coating to reduce heat transfer and improve energy performance.
3. Argon/Krypton Gas-Filled IGU
The air cavity is filled with inert gas for better thermal insulation.
4. Triple Glazing IGU
Three panes of glass for maximum thermal and sound insulation.
Benefits of Using IGU
• Energy Efficiency – Lower heating and cooling costs.
• Sound Insulation – Reduced noise from outside environments.
• Condensation Control – Less moisture on glass surfaces.
• Safety & Security – Can be combined with laminated or tempered glass for extra strength.
Applications of IGU
• Residential windows and doors
• Commercial curtain walls
• Skylights and atriums
• Soundproof office partitions
