Waterproof and breathable
- Provides reliable seal against water from outdoors
- At the same time, the membrane has sufficient diffusion permeability to allow water vapour from indoors to diffuse outdoors, thereby preventing moisture-related damage to buildings
- Thanks to its high-quality and flexible material, the EPDM film remains permanently sealed and compensates particularly well for component movements
- Its high UV and weathering resistance make the EPDM film ideally suited for permanently secure sealing
- Reliable installation is also achieved on slightly uneven construction surfaces, when combined with EPDM sealing tape adhesive
- Good compatibility with bitumen
Not suitable for seals in accordance with the water influence classes W2.2-E (high exposure to pressurised water ≥3 m immersion depth), W3-E (non-pressurised water on ceilings covered with earth) according to DIN 18533, as well as seals against pressurised water according to DIN 18195-6.
Tape cannot be plastered over.
Datasheets(X)
Permanent, reliable sealing of joints outdoors, e.g. for window sills, floor-level windows and balcony doors, for outside door sills, conservatories and in façade area.
- Thickness 1.2 mm: Joints behind perimeter insulating materials
- Corresponds to the following water influence classes from DIN 18533
- W1.1-E: Floor moisture and non-pressurised water for floor panels and walls in contact with the ground
- W1.2-E: Floor moisture and non-pressurised water for floor panels and walls with drainage in contact with the ground
- W2.1-E: Moderate influence from pressurised water ≤ 3 m immersion depth
- W4.E: Spray water on the wall socket as well as capillary water in and under walls in contact with the ground
- The surfaces must be dry, dust- and grease-free and capable of bearing loads.
- Installation: Cut the EPDM tape to the required length. Apply the EPDM sealing tape adhesive to the surface and wipe off with a spatula. Glue the EPDM tape to the surface and press on lightly using a press-on roller, while ensuring tension-free installation.
- On the frame/element, the sealing tape in the version with self-adhesive strips and/or with the sealing of components in contact with the ground must be fixed in place according to DIN18533 with a mechanical assembly.
