Eurovent AKTIVBAND SK Internal Window Sealing Tape 70 mm × 25 m, Sd 10 m

Eurovent AKTIVBAND SK internal window sealing tape is a vapour-resistant window and door installation tape designed for airtight and vapour-resistant sealing of window and door installation joints on the interior side of buildings. It is suitable for warm window installation systems and helps protect installation joints against indoor water vapour and uncontrolled airflow.

Eurovent AKTIVBAND SK is manufactured from a special polypropylene (PP) nonwoven fabric, a vapour barrier film and acrylic dispersion adhesive. The adhesive covers the entire width of the tape, allowing it to be bonded to both the window or door frame and the surrounding wall surface.

With an Sd value of approximately 10 m, the tape helps limit water vapour migration from the interior into window and door installation joints. When correctly installed, it also helps reduce air leakage around building openings.

The material has an area weight of 230 g/m², reaction to fire class E and temperature resistance from −40 °C to +80 °C. The tape is UV-resistant and intended for interior applications.

Each roll measures 70 mm × 25 m. The minimum application temperature is +5 °C.

Applications & Usage

Eurovent AKTIVBAND SK window sealing tape is used for sealing the interior side of window and door installation joints. It forms the internal vapour control layer of the installation joint, helping prevent humid indoor air from entering the joint.

Typical applications include:

• Interior sealing of window installation joints

• Interior sealing of door installation joints

• Warm window installation

• Connecting window and door frames to surrounding wall structures

• Reducing air leakage around building openings

• Protecting installation joints against indoor water vapour

• New window and door installations

• Window and door replacement during renovation

The tape is installed on the interior side of the building, with the adhesive bonded to the window or door frame and the surrounding wall surface. Its full-width adhesive layer makes installation easier.

The minimum application temperature is +5 °C.

A separate version, Eurovent AKTIVBAND SK2, is available to order with an additional 20 mm adhesive strip. This is a different product variant and is not part of the standard AKTIVBAND SK construction.
