Grommet for the windtight sealing of roof lining and sarking membranes and wood fibre boards (in conjunction with TESCON PRIMER) to pipes of vent tiles.
The size of ROFLEX exto makes it easy to bond to the roof sarking or roof lining under the positioned vent tile. If required, the grommet can be cut to flexibly adapt to the respective sealing situation. The adhesive patch is permeable. The impermeable EPDM section is reduced to the necessary extent.
