Product data
Field of application
- for trouble-free seals at penetration points such: rafters, outlet vents, electrical ducts
Advantages
- high elasticity
- a tape for all penetrations
To guarantee air and wind-tightness for the skin of a construction it must have the appropriate foils or panel materials providing a permanent seal at overlaps, gaps, joints and penetration points. BUTYL Dehnflex - Stretch Flex is used particularly as a seal at penetrations points for wind seals, vapour barriers, roof underlays and OSB. Due to its great flexibility the tape can easily be positioned around the openings that require sealing and neatly pressed down. Its extremely good adhesive properties permit work on a variety of substrates mostly without a primer.

Processing guideline
INFO
The materials used must be free from dust and grease and substrates must be dry and supporting.The greater the pressure applied, the better the performance of the adhesive tape.
BUTYL Stretch Flex has the function of sealant and not of a strong connector. Optimum adhesion to the substrate is achieved in combination with BUBI LF Bonding Primer or UNI Primer.
( ! )
Butyl and bitumen tapes have a high inherent weight. The tape must be mechanically secured in case of installation in projecting areas e.g. ceilings, cantilevers and soffit areas, where gravity acts directly on the tape.
