ROFLEX 30
Sealing grommets for pipes, Ø 30-50 mm (1 3/16”-2"), for interior and exterior use
Advantages
- Keeps building components dry: quick and simple sealing
- Reliable joints thanks to TESCON VANA or TESCON INVIS with water-resistant SOLID adhesive
- Reliable even in hot environments: stable at temperatures up to 150 °C
- Practical handling: pipes can be pushed and pulled through the grommet – the joint remains sealed
- Extremely flexible and elastic, no protruding sleeve
- Construction in adherence with standards: for airtight sealing in accordance with DIN 4108-7, SIA 180 and RE 2020
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
Areas of application
For quick, permanently sealed feedthroughs of pipes through the airtightness layer. Also for exterior use, e.g. for underlays or refurbishment vapour checks. Tape with TESCON VANA or TESCON INVIS.
Installation instructions
Installation steps
General conditions
The bonds should not be subjected to tensile strain. Rub the adhesive tapes firmly to secure the adhesive bonds. Ensure that there is sufficient resistance pressure.
Windproof, airtight or rainproof sealing can only be achieved on vapour checks, roofing underlays or breather (WRB) membranes that have been laid without folds or creases. Ventilate continuously and systematically to prevent build-up of excessive humidity; use a dryer if necessary.
Substrate
Clean subsurfaces before sticking. Adhesion to frozen surfaces is not possible. There must be no water-repellent substances (e.g. grease or silicone) on surfaces where adhesives are to be applied. Subsurfaces must be sufficiently dry and stable.
Permanent adhesion is achieved on all pro clima interior and exterior membranes, other vapour check and airtight membranes (e.g. those made of PE, PA, PP and aluminium) as well as other roof and breather (WRB) membranes (e.g. those made of PP and PET).
Adhesive bonds are possible on planed and painted wood, hard plastics and metal (e.g. pipes, windows etc.), hard wood-based panels (chipboard, OSB, plywood, MDF and wood-fibre underlay panels). Pre-treatment with TESCON PRIMER is required in the case of adhesion to wood-fibre underlay panels and smooth mineral subsurfaces. Concrete or plaster subsurfaces must not be sandy or crumbling.
The best results in terms of structural stability are achieved on high-quality subsurfaces. It is your responsibility to check the suitability of the subsurface; adhesion tests are recommended in certain cases. Pre-treatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient stability.
