Description
Durable closed cell polyethylene foam used beneath sealants to set joint depth and prevent three-sided adhesion. Enhances movement capability, reduces sealant use, and supports clean tooling. Suitable for polyurethane, hybrid, and silicone sealants in façades, precast, and pavement joints. Non-absorbent, compressible, and easy to handle on site. The 20mm x 60m roll suits larger joints and expansion interfaces for internal and external projects, improving seal longevity and overall system performance in demanding construction environments.
