is a one-sided adhesive tape, based on expanded polyethylene foam and supplied in rolls.
is an installation accessory for all ventilated roof constructions with or without sarking, using JUTADACH or JUTATOP roofing underlays, where counter battens sealing is required. JUTAFOL TPK seals the nail or screw penetrations of the underlay caused by the installation of counter battens.
is positioned in between the underlay and the counter batten, with all nails or screws going through it.
Using JUTAFOL TPK
prevents local water leakages within rafter areas, and therefore supports the weather-tightness of the complete roof system.
Using of JUTAFOL TPK
is suggested especially with pitched roofs of lower slope and without sarking. The installation of thermal insulation from underneath might cause bulging of underlay and consequently drain the moisture to the counter battens, making it more susceptible to leakages through nail and screw penetrations.
continues sealing for its whole lifetime, due to its elastic expanded foam structure, which creates a long-lasting functional sealing layer.
