Double-sided butyltape
BUTYL
The double-sided butyl tape Eurovent® BUTYL is designed for joining and sealing vapour-barrier foils and roof membranes, roof membranes, foundation films and other construction products based on plastics. Made on the basis of butyl, solvent-free, protected with a layer of foil. It is a friendly product for people and the environment.
Advantages:
- High adhesive strength
- UV resistance
- Water-tightness
Application and Technical Data
The double-sided butyltape Eurovent BUTYL is designed for joining and sealing roofmembranes and foils, construction foils as well as foils applied for foundation and vapourinsulation. Effectively bindsall kinds offoilswith plastics, concrete, brick or metal elements.Recommended for application in finishing works around chimneys and other elementsprotruding above the surface of the roof. When applied with foundation foils, thetapeensures that the overlaps are tightly sealed and protected against the penetration of groundwater.

System products
To ensure maximum performance of BUTYL, it is recommended to use it as part of a complete roofing system together with:
- Eurovent® roof membranes (roof underlays / underdeck membranes), which create a stable substrate for durable and flexible sealing with BUTYL,
- Eurovent® vapour control membranes (vapour barriers), where BUTYL ensures airtight and ageing-resistant sealing of detailing areas and service penetrations,
- Eurovent® sealing and adhesive tapes, complementing the performance of BUTYL in areas requiring additional reinforcement and enhanced airtightness,
- Eurovent® metal flashing elements, where BUTYL performs as a flexible, high-adhesion seal between metal components and adjacent roofing layers.
The use of complete Eurovent® system solutions guarantees durable sealing, effective protection against moisture ingress and long-term reliability of the entire roof structure.
GOOD TO KNOW
Where is double-sided BUTYL tape useful?
For connecting roof membranes, vapour control layers, foundation films and other insulation materials to concrete, brick, metal or plastics.
Why does butyl work well for sealing?
It remains permanently pliable, adheres very well to the substrate and creates a watertight joint without solvents.
Can BUTYL be used around foundations?
Yes. The tape is suitable for sealing overlaps in foundation films and areas exposed to moisture and groundwater.
Is it useful for chimney flashing?
Yes. It can form a tight connection between films or flashing components and other building surfaces.
Does BUTYL remain visible after installation?
It usually works between the layers being joined, so it primarily acts as a concealed sealing component.
