DAFA vapor barrier tape 

Used for indoor joins in all PP/PE membrane types, as well as plywood, chipboard, planed wood and metal. Available from DIY stores and timber merchants nationwide.

DAFA vapor barrier tape is included in the Nordic Ecolabellings database of construction products that can be used in Swan-labelled buildings.

BLUE VAPOR BARRIER TAPE
FOR LONGITUDINAL AND TRANSVERSE JOINS

Blue vapor barrier tape is used for longitudinal and transverse joins in vapor barrier foil. The tape adheres to materials such as PP/PE membranes, plywood, planed wood, chipboard and metal. The tape has very strong adhesion, that improves over time, and is resistant to moisture and other climatic changes.

GREEN VAPOR BARRIER TAPE
FOR SEALING AROUND SHAPED ELEMENTS

Green vapor barrier tape is also part of the DAFA AirStop System. The tape is used for sealing around vents, pipe and cable penetrations (where DAFA's universal pipe and cable collars cannot be used), air ducts and corners. Green vapor barrier tape is very flexible and stretchable, allowing movement of the building elements.

Material

The multilayer structure with reinforcing mesh ensures an extremely stretch and tear-resistant vapor barrier foil. The foil must not be exposed to direct contact with wood preservative with added solvents.

Advantages of blue tape

• Ideal for longitudinal and transverse joins in membranes
• Easy to trim without the use of tools
• Highly adhesive

Advantages of green tape

• Ideal for pipe penetrations where DAFA's universal pipe and cable collars cannot be used
• Flexible/stretchable
• Highly adhesive

NB: DAFA vapor barrier tape is a strongly adhesive tape which should only be used in permanent applications, as the tape cannot be removed from the surface again!
