Butylver Series

Butylver, Premium PIB-Based Primary Sealant for High-Quality Insulation Glass Units

Butylver is a primary sealant that serves as the first barrier for internal insulation (Butyl) in insulating glass systems. Made from polyisobutylene (PIB), it is a single-component, solvent-free solution designed to seal spacer edges effectively, preventing moisture ingress and gas escape. Renowned for its high stability, extensive compatibility, and versatility across various IGU configurations, Butylver also holds CEKAL certification.

The Butylver series offers various versions tailored to different applications:

Butylver Standard: designed for use with rigid spacers and is available in black or grey.
Butylver SS: specifically formulated for use with flexible spacers.
