Black airtightness tape – Ampacoll UV Flexx – 60mm x 40m

Product overview

Where is it used?

• Ampacoll UV Flexx is used behind open facades for taping joins and around openings in facade membranes such as the Ampatop RF Black membrane.
• Used externally in locations where UV exposure is to be expected.

How is it used?

• If necessary, clean the surfaces to be bonded or the substrate.
• Cut the Ampacoll® UV Flexx to the desired length and ensure the centre of the tape is on the overlap so that an even amount of tape is applied to both pieces of membrane
• Firmly press the adhesive tape, ideally with a pressure roller, to ensure the durability of the bond.
• When sealing around penetrations, such as vent pipes etc. ensure at least 30mm lap of Ampacoll® UV Flexx on to the penetration and to the membrane. Firmly press the tape to ensure good bonding.
• For the adhesive tape to fully function, counter battens are required for securing the membrane to avoid possible loads from working and from weather conditions (e.g. wind suction and pressure).
• We recommend the facade cladding is installed as fast as possible but it can be left for up to 3 months if required.
• The joint width may be up to a maximum of 5 cm so long as the individual strips of cladding are at least 100mm. E.g. ensure the strips/panels are at least twice as wide as the gaps.

How much will you need?

Each roll of Ampacoll UV Flexx is 60mm wide and 40m long. From experience, consumption rates are around 1m of tape per m² of wall although this will increase if there are lots of windows.
