Expansion Tape

EXPANSION TAPE is a precompressed, selfadhesive foam tape with a synthetic coating that is impregnated with aluminium oxide. This impregnation ensures that the tape adheres to the joint partition and protects the tape mainly against the weathering and ageing. The tape retains the tensile strength even in cold temperature. The tape meets the Class B1 fire standards. EXPANSION TAPE is a BG1 approved foam tape, making it suitable for sealing joints, seams and flanges, ... as well as offering protection against humidity, dust, heat loss and noise. EXPANSION TAPE is water-resistant and UV-resistant.EXPANSION TAPE remains pressed against both walls in a constant and powerful way.

  • Fills in all uneven gaps.
  • Offers protection against humidity, dust, noise, cold loss and heat loss, ...
  • Has a water-resistant finish.
  • Very good UV protection.
  • Very slow expansion.
  • Does not show any signs of ageing thanks to its synthetic coating.
  • Free of bitumen and does not run.
  • Foam tape is impregnated with fire-resistant aluminium oxide.
  • Suitable for even and uneven surfaces.
  • Meets the BG1 standard and Class B1 fire standard.

  • Expands very slowly, so it can be applied straight from the roll the higher the ambient temperature, the faster the adhesion.
  • Finishing of the most common joints, seams and flanges.
  • Joining of masonry with door frames and window frames, concrete columns, façade and roof elements, dilatation joints.
  • After use, the roll must be fastened with a piece of tape to prevent swelling.
