An Insulated Glass Unit (IGU) is a type of glass assembly that consists of two or more panes of glass separated by a spacer and a gap, typically filled with air or gas. The spacer is usually made of metal or plastic, and the gap is usually around 1/8 inch (3-4 mm) wide. The IGU is designed to reduce heat transfer between the interior and exterior of a building, while also providing acoustic insulation and minimizing condensation.
Where it is used:
IGUs are widely used in various applications where energy efficiency, thermal insulation, and sound reduction are important. Some common examples include:
- Windows: IGUs are commonly used in window manufacturing, particularly in double-hung, casement, and sliding windows.
- Doors: IGUs are used in door manufacturing, including exterior doors, interior doors, and revolving doors.
- Skylights: IGUs are used in skylight manufacturing to provide natural light and insulation.
- Greenhouses: IGUs are used in greenhouse construction to provide insulation and reduce heat loss.
- Mobile homes: IGUs are used in mobile home construction to provide insulation and energy efficiency.
- Commercial buildings: IGUs are used in commercial buildings, such as offices, hospitals, and shopping centers, to provide energy efficiency and acoustic insulation.
- Residential buildings: IGUs are used in residential buildings to provide energy efficiency, thermal insulation, and sound reduction.
The benefits of IGUs include:
- Reduced heat transfer
- Improved sound reduction
- Minimized condensation
- Increased energy efficiency
- Improved durability and lifespan
Overall, IGUs are an essential component in many building applications where energy efficiency, thermal insulation, and sound reduction are important.
