Expanding Foam Tape for Reliable Joint Sealing

Xpanda 600 is a pre-compressed, expanding joint sealing tape manufactured from soft polyurethane foam, modified with stabilised acrylics. Once installed, it expands gradually to fill the joint, forming a durable seal against rain while allowing the joint to breathe.

The self-adhesive scrim backing makes positioning simple and accurate, particularly around window and door frames where neat installation matters.

How it Works

After installation, the tape slowly expands to match the joint width. Its permanent elasticity allows it to accommodate ongoing expansion and contraction caused by temperature changes or structural movement.

This flexibility helps maintain:

  • Consistent weather resistance
  • Long-term thermal insulation
  • Sound insulation
  • A tight seal, even against uneven substrates
  • Performance You Can Rely On

    Xpanda 600 is tested to resist driving rain up to 600 Pascals at 25% decompression, making it suitable for exposed elevations and challenging UK weather conditions.

    Additional performance benefits include:

  • High UV resistance
  • Stable ageing without cracking or splitting
  • Vapour permeability to reduce condensation risk
  • Resistance to mould and mildew build-up
  • These characteristics make it particularly effective in environments where seasonal movement and temperature variation are expected.

    A Cleaner Alternative to Aerosol Foam

    As an Expanding Foam Tape, Xpanda offers a more controlled and environmentally responsible approach compared to traditional canister foams.

    Key advantages include:

  • No empty canisters or chemical propellants
  • No release of CFCs (chlorofluorocarbons)
  • Reduced fire risk during installation
  • No overspray or post-installation cleaning
  • No need for applicator guns or solvents
  • Minimal site waste
  • Because the tape expands only within the joint space, installation is predictable and efficient.

    It is compatible with most standard sealants and can be overpainted with water-based acrylic or latex coatings once in position.
