Tesa® Vapour Barrier Tape User Guide

1. Overlapping Joints

Overlap air and vapour barrier substrates by at least 10 cm.
Centre and fix the tape on top of the overlap.
Press the tape firmly against the barrier substrate, working carefully to avoid wrinkles and air entrapment in the joint.
Do not overstretch the tape during application.

2. Pipe penetrations

Pre-fold the tape in half.
Overlap the individual pieces of tape at a slight angle with an overlap of approximately 30 % to completely surround the penetration.
Press each piece of tape by hand with firm pressure.
For added protection, overlap the pieces of tape adhered to the pipe with an additional piece of tape and use small pieces of tape to secure the tape adhered to the barrier substrate.

3. Cable penetrations

For small cable entries at least two pieces of sealing tape with a width of at least 110 mm are required.
Cut each of the ribbons in half in the middle position.
Place the first piece of tape around the bottom of the cable, positioning the groove position around the penetration with firm pressure.
Then, place the second piece of tape on top, overlapping the first piece of tape with firm pressure to ensure a watertight connection.

Attachment with wooden rafters

Cut the air and vapour barrier substrates around each of the wood joists. Each cut should be made sparingly so that there is a small overlap of the air and vapour barrier and the wood joist.
Cut carefully at the corners to achieve a perfectly positioned air and vapour barrier on the wooden beam without wrinkles and stresses.
Apply tape at each of the overlapping positions between the air and vapour barrier and the wood joist. Fold the tape inwards at the corners to ensure a watertight connection. Press the tape down firmly.

5. Repairing tears

Smaller tears, less than 40 mm in diameter, can be repaired with two pieces of sealing tape.
Overlap the tape by approximately 30 % of the width. Larger holes should be repaired with a patching system.
Cut a patch larger than the hole or tear with an overlap of at least 30 mm on each side.
Secure the patch with a piece of tape on each side.
Press firmly to obtain an airtight connection with no air channels present.
