Glazing tapes are used primarily in installing glass panels, particularly in windows, doors, curtain walls, and other glazing systems. Their main functions are:

1. Sealing
Glazing tapes provide an airtight and watertight seal between the glass and the frame. This helps:
  • Prevent air and water infiltration
  • Improve energy efficiency
  • Reduce noise

2. Cushioning
They act as a cushion to absorb shocks and vibrations, which protects the glass from cracking or breaking due to movement or impact.

3. Adhesion
Depending on the application, some glazing tapes (especially double-sided foam tapes) help bond the glass to the frame temporarily or permanently.

4. Spacer Function
Glazing tapes can also serve as spacers to maintain uniform spacing between the glass and the frame for structural or aesthetic reasons.

Common Types of Glazing Tapes:

  • Butyl tapes – known for strong sealing against moisture
  • Foam tapes – typically used for cushioning and bonding
  • PVC or EPDM tapes – durable and weather-resistant, often used in commercial installations

Applications:

  • Residential and commercial windows
  • Storefront glazing
  • Skylights
  • Glass partitions
  • Curtain wall systems
