Insulating Glass (IGU)

Where Soundproofing Meets Energy Savings

Insulating Glass Units (IGUs) consist of two or more glass panes separated by a spacer and sealed to create an airtight unit. Typically filled with inert gases such as argon, IGUs provide excellent thermal and sound insulation, making them ideal for a variety of commercial and residential applications.

  • Heat Insulation – Reduces heat transfer for energy savings.
  • Temperature Management – Minimises temperature fluctuations between indoor and outdoor environments.
  • Sound Insulation – Effective in reducing noise transmission.
  • Energy Efficiency – Helps to lower energy bills by improving building insulation.
  • Condensation Prevention – Prevents interior glass fogging and mold growth.
  • Gas Filling – Enhances thermal insulation with argon gas.

Types of Spacer

The spacer plays a crucial role in the performance of IGUs by maintaining a consistent gap between the glass panes and improving insulation. We offer two types of spacers:
