Where is it used?
Ampacoll INT interior airtightness tape is designed for internal use for taping joints around windows/doors, on OSB or ply, sealing around pipes and wires and can be used for taping sole plates to slabs/screeds.
Due to the special surface on the Ampack vapour control membranes, the Ampacoll INT tape also forms a very strong join between laps in membranes.
