Breathable airtightness tape - Ampacoll XT


Ampacoll XT breathable airtightness tape is:-

  • a 60mm wide universal, single sided, tear-resistant, acrylic adhesive tape.
  • suitable for internal and external use, in corners and apexes.
  • highly adhesive and suitable for bonding all types of membranes as well as boards.
  • suitable for winter use down to -5 degrees C.
  • resistant to exposure for up to 4 months.

Where is it used?

  • Ampacoll XT can be used internally or externally and has been optimised to withstand the more challenging conditions found externally.
  • The breathable tape is suitable for taping all types of internal and external breathable membranes and vapour control membranes.
  • Ampacoll XT can be used for taping all types of timber boards such OSB, ply, MDF and wood fibre boards with the use of primer.

How is it used?

  • Surfaces should be clean, dry and free of dust before the tape is applied. 
  • The paper backing needs to be peeled off prior to use and can either be cut to length and then applied or applied straight off of the roll.
  • On lightly textured boards like OSB a roller should be used to firmly press the tape into position. 
  • If you are taping to concrete/masonry or wood fibre boards the UdiSTEAM Primer should be applied and left to dry first. This ensures that the tape will stick properly to these surfaces.

How much will I need?

  • Each roll of Ampacoll XT tape is 60mm wide and 25m long. 
  • For taping OSB boards allow 4-5m per m2 of wall/roof. 
  • For membranes allow 1-2m per m2.

This product can be bought by the 60mm x 25m roll or in boxes of 10 rolls (10% cheaper than single roll cost)
