“One of the most elastic tapes we’ve found, ideal for taping fleece covered membranes and those with no boards behind them” – Chris Brookman

Product overview.

Where is it used?

  • Ampacoll Flexx airtightness tape is designed for external and internal use and is ideally suited to taping laps and joins in membranes, particularly where the membrane is laid directly on to soft insulation.
  • Because of it’s elastic nature, it is great for sealing around pipes and wires and can be used for taping sole plates to slabs/screeds.

How is it used?

  • Surfaces should be clean, dry and free of dust before the tape is applied. 
  • Membranes should not have wrinkles in them, particularly with very stiff membranes and the tape should be gently smoothed out with the Ampack Pressly spreader once in place.
  • On lightly textured boards like OSB a the Ampack Pressure Roller should be used to firmly press the tape into position. 
  • When taping OSB or similar boards do not apply in hot/strong sun as it can cause the tape to wrinkle.

Material in action.

In this image you can see the Ampacoll Flexx tape being used for joining laps in one of the Ampatop breather membranes. The tape will stick tightly to fleecy membranes such as this and its soft, pliable nature means it is easy to work with on membranes laid directly on soft insulation.

Airtightness tapes are designed to be able to move and having wrinkles and creases in a membrane tends to very slowly separate the two layers. This is not the fault of the tape is it needs to be able to move with the building and is not designed to resist any tension between the two layers of membrane.

If you’re unsure of how to instal membranes or how to lap them effectively, please contact us.
