Expansion Tape

EXPANSION TAPE is a compressed swelling tape for storm-resistant sealing, with a polymer impregnation for long-term stability. The BG1 classification of EXPANSION TAPE guarantees complete wind and water tightness (driving rain) up to wind force 11 at a building height of 100 metres. In addition, EXPANSION TAPE is almost completely vapour permeable (Sd-value 0.5), which corresponds to current building requirements. Due to its slow expansion, the tape can be applied from the roll. EXPANSION TAPE can be painted or plastered, but is itself UV and weather resistant.

  • 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.

Technical information and packaging
Tape composition: Polyurethane foam
impregnation / polymer dispersion.
Adhesive: synthetic rubber.
Colour: grey.
DIN 18542 class: BG1.
Rain resistance: > 600 Pa (wind force 11).
Water vapour permeability: Sd ≤ 0.5 (= open to
vapour).

Windtightness: windproof according to EN 1026.
Insulation value: λ (lambda) = 0.043 W/mK.
Fire behaviour DIN 4102: B1 (fireproof material).
Temperature resistance: 30°C to +90°C.
Processing temperature: +5°C to +35°C.
Can be painted: yes.
Shelf life: 18 months, stored in cool, dry
conditions in the original packaging.

  • Applications:
  • Sealing of construction joints such as those in windows, doors and facades.
  • Sealing of expansion joints in facades.
  • Windproofing of joints and roof linings.
  • Acoustic and thermal insulation of prefabricated buildings and timber frames.
  • Alternative or supplement to polyurethane foam (the use of the expansion strip during the installation of windows creates a wellfinished edge on the outside, which guarantees watertightness and at the same time forms an effective barrier for the possible application of polyurethane foam as additional insulation).
  • Use:
  • Apply to stable, dry and clean surfaces. Parallel joints will ensure optimum clamping results.
  • Use a tape clamp to prevent the roll from stretching.
  • Remove the protective film and stick the tape into the joint without stretching it. Apply 2-3 mm from the outside of the joint for an aesthetic result. Apply from bottom to top and press with a spatula.
  • Apply in straight lines, without bends.
  • To avoid moisture penetration:
    - In corners: apply the horizontal strip first, then the vertical piece.
    - For cross-connections: first apply the vertical strip along the entire length. Then the horizontal pieces.
