Double-sided butyl tape
BUTYL PRO
The double-sided butyl tape Eurovent® BUTYL PRO is designed for joining and sealing roof membranes, wind-barrier membranes, vapour–barrier and roof foils as well as for sealing roof and building structures. It is made on the basis of butyl, solvent-free and protected with a layer of foil. It is a friendly product for people and the environment.
Advantages:
- High adhesive strength
- Wide adhesive area
- UV resistance
- Watertightness
Application and Technical Data
Eurovent® BUTYL PRO double-sided butyl tape is used primarily beneath counter-battens to seal the points where nails and roofing staples penetrate the roof membrane. It is also used for joining and sealing vapour control films and roofing films to plastics, concrete, wood, brick and metal components. It is suitable for bonding and sealing housewrap membranes in timber-frame construction.

System products
To ensure maximum performance of BUTYL PRO, it is recommended to use it as part of a complete roofing system together with:
- Eurovent® roof membranes (roof underlays / underdeck membranes), which provide a stable and airtight substrate, enabling durable, flexible and weather-resistant sealing with BUTYL PRO,
- Eurovent® vapour control membranes (vapour barriers), where BUTYL PRO guarantees secure and ageing-resistant bonding of overlaps and connections between the membrane and structural elements,
- Eurovent® sealing and adhesive tapes, complementing the performance of BUTYL PRO in areas requiring additional reinforcement and enhanced airtightness,
- Eurovent® metal flashing elements, where BUTYL PRO performs as an exceptionally durable and flexible seal between metal components and adjacent roofing layers.
The use of complete Eurovent® system solutions guarantees maximum sealing durability, effective protection against moisture ingress and reliable long-term performance of the entire roof structure.
GOOD TO KNOW
Why does BUTYL PRO work well beneath counter-battens?
It has a wide bonding surface and remains pliable, allowing it to effectively seal the areas where nails or screws penetrate the membrane.
How does it differ from standard BUTYL tape?
BUTYL PRO is designed particularly for wide structural seals, including beneath counter-battens, whereas BUTYL has a more universal role in joining different insulation materials.
Is BUTYL PRO suitable for timber-frame construction?
Yes. It can also be used to seal and join housewrap membranes in framed structures.
Can it connect a membrane to wood or concrete?
Yes. Butyl bonds films and membranes well to wood, concrete, brick, metal and many plastics.
Is the tape water-resistant?
Yes. It is watertight and intended for durable sealing applications.
