Defence Adhesive Traspir Evo - Monolithic Breathable Membrane
Verified by manufacturer 2 days ago
A self-adhesive breathable monolithic membrane providing water protection and high breathability with durable adhesive.
Application
Used to protect structural elements during transport and on construction sites while maintaining the hygrothermal behaviour of components by applying a breathable monolithic membrane layer.
Description
A self-adhesive breathable monolithic membrane providing water protection and high breathability with durable adhesive.
Features and benefits:
- The homogeneous and continuous monolithic functional layer provides maximum protection against the passage of water and high breathability.
- The special compound ensures significant weather resistance and durability over time.
- The (polyurethane) PU top layer provides water impermeability, excellent durability and resistance to construction site stresses.
- The acrylic dispersion glue ensures breathability and does not alter the properties of the functional film of the membrane.
- The special glue provides long-term performance, UV stability and water resistance, offering optimal adhesion at both high and low temperatures.

Shear adhesion strength of the joint on DEFENCE ADHESIVE TRASPIR after 24 hours to EN 12316-2, 150 N/ 50 mm. Guidance for specification option: Adhesion strength on (average) on DEFENCE ADHESIVE TRASPIR after 24 hours: minimum required value according to DTU 31.2 P1-2 (France): 15 N/ 50 mm. Shear adhesion strength of the joint on DEFENCE ADHESIVE TRASPIR after 24 hours: minimum required value according to DTU 31.2 P1-2 (France): 40 N/ 50 mm. |
UV stabilization | To 13859-1/ 2, 1000 hours (8 months). Guidance for specification option: Laboratory ageing tests are not able to reproduce the unpredictability of the product's degradation or the stresses to which it will be subjected during its service life. To ensure its integrity, it is recommended to limit the time of exposure to the weather during the construction phase to a maximum of 10 weeks. According to DTU 31.2 P1-2 (France), UV ageing of 1000 hours allows a maximum exposure of 3 months during the construction phase. |
