Insulated Glass Unit (IGU) is the leading energy-saving solution for high-rise buildings and commercial projects. With a special structure consisting of multiple glass layers and an air/inert gas space, IGUs offer superior thermal insulation capabilities.
Structure of Insulated Glass
- 2-3 glass layers: Can be annealed, tempered, or Low-E glass
- Spacer bar: Creates a gap between glass layers (usually 6-16mm)
- Inert gas: Argon or Krypton is filled into the cavity
- Desiccant: Absorbs moisture, preventing condensation
- Double sealant: Butyl and Silicone/Polysulfide
Cost Savings
Insulated glass can reduce air conditioning costs by 30-50% compared to single glazing, especially effective in hot climates like Vietnam.
Superior Features
- Thermal Insulation: Reduces heat transfer, keeping interiors cool in summer and warm in winter
- Sound Insulation: Reduces external noise by up to 35dB
- UV Protection: Combined with Low-E to block up to 99% of harmful UV rays
- Condensation Resistance: minimize condensation on the glass surface due to temperature differences
Suitable Applications
- Curtain walls for high-rise buildings
- Windows and doors for villas and townhouses
- Glass roofs and skylights
- Meeting rooms and offices requiring soundproofing
