Installation instructions for Vapora Vario SD vapor retarder

Step 1: Laying and fixing the vapor barrier
Lay the ALMO Vapora Vario vapor barrier on the rafters and fix it either with a stapler or by masking it with the ALMO TwinTape.

Step 2: Overlapping installation and airtight connection
Lay the second vapor barrier film with an overlap and also fix it in place either with ALMO TwinTape or by stapling. Connect the two vapor retarders with the Versa® Uni Tape 60 Adhesive tape for additional sealing. Use the overlap guide line for an overlap of 10 cm. For airtight bonding, you can use the auxiliary line at 30 mm to ensure optimum sealing with the 60 mm wide Versa® Uni Tape 60.

Step 3: Airtight bonding of the folds
To ensure an airtight seal, tape the folds of the vapor barrier in a T-shape with the Versa® Uni Tape 60 .

Step 4a: Transverse counter battens and protective cladding
Attach counter battens across the structure to support the weight of the insulation material. Then install the interior cladding to protect the vapor barrier from mechanical influences.

Step 4b: Longitudinal installation for heavy insulation materials
For wide rafter bays or heavy insulation material, we recommend laying the Vapora Vario SD in the direction of the rafters and installing the counter battens lengthways.

Step 5: Terminating and sealing penetrations
For penetrations such as pipes, make a star-shaped cut and seal the pipe with small pieces of the Versa® Uni Tape 60 off. Alternatively, a flange can be inserted and securely bonded with Versa® Uni Tape 60.
