Multifunctional Joint Sealing Tape – Ampacoll Komprimax

Ampacoll Komprimax joint sealing tape is:-

  • an airtight, expanding PU foam tape, for sealing window & door frames into openings.
  • ideal for preventing weather penetration around windows and doors.
  • suitable for timber frame, blockwork or stone walls.
  • a permanently flexible, UV stable, weathertight seal.

Product overview

Where is it used?

  • Ampacoll Komprimax M joint sealing tape can be used to seal around all types of window and door frames as well as pipework and other service penetrations.
  • Can be used below ground in conjunction with other sealing tapes such as Ampacoll BK535 butyl tape or Ampacoll Fenax.

How is it used?

  • Ampacoll Komprimax M joint sealing tape is best kept cool prior to use.
  • In hot weather keep it in the fridge or other cool place prior to use.
  • Ensure the surface to be bonded to is clean, dry and free from dust.
  • Allow plenty of overlap in the corners of the frames to ensure the tape fills the whole void around the window/door frame.
  • Ampacoll Komprimax M joint sealing tape will slowly expand over several hours in cool conditions. Heat increases speed of expansion.

How much will you need?

Each roll of Ampacoll Komprimax is 8m long and either 60 or 90mm wide. Ensure that you measure the tight dimensions of the opening (not the frame) when calculating how much you need.

Frequently asked questions

Do I need to tape the joints?

No. The external sealing tape will seal any joints from weather penetration.

How long can I leave it exposed?

This tape is not UV stable in the long term so should be protected from sunlight as soon as is practicable. This is usually achieved by sealing the external face of the frame with the appropriate Ampacoll tape.
