Expanding tape

COMPRE X

Single-sided expanding tape made of flexible polyurethane foam impregnated with modified acrylic. The pre-compressed tape expands after installation, increasing its thickness up to five times. Its primary applications include sealing joints and gaps, as well as providing thermal and acoustic insulation.

Advantages:

  • Fills joints and gaps
  • Water-resistant
  • Highly flexible
  • Protects against wind, cold and moisture
  • Provides thermal and acoustic insulation

Application and Technical Data

Suitable for sealing gaps in building and roofing structures, particularly in ridge, valley and roof window areas. It effectively seals joints and cavities, including those around roof valleys, providing reliable protection against moisture, wind, rain and cold. The tape adheres excellently and adapts to a variety of substrates, including wood, brick, metal and smooth concrete, ensuring durable and long-lasting sealing performance.

System Products

To achieve maximum performance of Eurovent® COMPRE X, it is recommended to use it as part of a complete system together with:

  • Eurovent® roof membranes, which protect the roof structure against moisture and work in conjunction with the sealing provided by COMPRE X in critical details and flashing areas,
  • Eurovent® vapour control membranes, where COMPRE X improves the airtightness of connections and helps maintain the continuity of the vapour control layer,
  • Eurovent® sealing and adhesive tapes, which complement the performance of COMPRE X in areas requiring enhanced airtightness and additional protection against water ingress,
  • Eurovent® installation accessories, ensuring the stability and correct positioning of roofing components sealed with COMPRE X.

The use of complete Eurovent® system solutions guarantees durable, flexible and weather-resistant sealing, effective protection against moisture penetration, and long-term reliability of the entire roof structure.

FAQ

GOOD TO KNOW

How does COMPRE X work after being unrolled?

The tape is factory-compressed. After installation it gradually expands and fills the gap. Its thickness can increase approximately fivefold.

Where on a roof can COMPRE X be used?

Around valleys, ridges, roof windows and other areas where an irregular gap needs filling.

Does the tape only fill the gap?

No. It also reduces the penetration of wind, rain, moisture and cold air and improves acoustic insulation.

Which substrates can it bond to?

Wood, brick, metal or smooth concrete, after proper surface preparation.

How is the COMPRE X size selected?

According to the width of the gap that the tape must fill after expansion. A version that is too small or too large may not function correctly.
