Window tape – Internal
AKTIVBAND SK2
The Eurovent® AKTIVBAND SK2 window vapour control tape is designed for the internal sealing of installation joints around windows, blinds and doors in the so-called “warm installation” system. It is made of a special nonwoven fabric combined with a vapour control film and is coated on one side across its entire width with a high-adhesion adhesive layer, facilitating application to the window frame or wall. The tape is additionally integrated with a 20 mm adhesive strip on the opposite side, which enables easy bonding to the window frame.
Advantages:
- Very low emission of hazardous substances – EMICODE® EC1 Plus
- Integrated additional adhesive strip
- Vapour-tight
- Eliminates thermal bridges
- Provides acoustic insulation and reduces energy consumption costs
- Protects against moisture, mould and fungal growth
