Tested sealing properties over 600 Pa, complies with BG1 requirements in accordance with DIN 18542

Tested air tightness properties (a < 0.1) meet BGR requirements in accordance with DIN 18542

Tested and assured sealing against driving rain

Time-saving application

Resistant to driving rain, heat-insulating and air-tight in a single product

Outwardly permeable to water vapour

The surface waterproofing on one side achieves the required vapour diffusion property of "tighter sealing on the inside than the outside".

Can be installed in any weather

The product provides completely secure sealing in virtually any kind of weather.

No chemical reactions with other materials


The tape is resistant to driving rain, but must also be sealed with butyl tape with laminated foil for standing water (e.g. horizontal and above) or water pressing on the seal, if the joint is not immediately covered following mounting. A second level leading water away (tub-shaped sealing film) must be created in the lower connection area, so that the water is diverted away to the outside in a controlled manner. The expansion speed of VKP Trio SF depends on the temperature. In high temperatures, store the tape in a cool location; in low temperatures, store in a warm location.
