FIELD OF USE

VAPORVLIES 85

LAYING INDICATIONSThe VAPORVLIES 85 vapour check membrane is placed parallel to the platform beam for application on roofs or to

the floor for application on walls. The second layer must be overlapped at least 15 centimetres over the first layer.Each layer must be fixed to the support with a mechanical fastening device (i.e. hammer tacker HH735347). Thetransparency of the fabric allows for clear viewing of the underlying substrate on which fastening will be performed.The fabric must be applied on the hot side of the roof or wall. We also recommend overlapping the fabric by at least30 centimetres in the butt joints.Use SEAL BAND (DZ100125/127) sealing band or FLEXI BAND (DZ100110/120) with rough surfaces (like raw OSB) forfurther air or water sealing.

PRODUCT STORAGE AND CARE

Keep the rolls in a dry place, away from heat and direct sunlight. It is also advisable to avoid overlapping of pallets.These actions are necessary to preserve the original features of the product.

NB:For the application of all Rothoblaas products, we recommend reading the installation instructions provided in
