EasyFLEX PIB Pre-Fabricated Inward Corners are designed to provide a simple, secure solution for sealing complex or tight junctions in vapor barriers and roofing systems. Suitable for both indoor and outdoor use—on roofs, balconies, terraces, and more—they offer fast, reliable installation without the need for a torch or heat gun.

Each corner is mounted directly onto the vapor barrier or building surface using SabetoFLEX Activator Spray, which displaces moisture and ensures excellent adhesion even on damp or wet substrates—making it ideal for unpredictable weather conditions or humid environments.

Material & Performance

Manufactured from high-performance, UV-resistant polyisobutylene (PIB), each corner piece has a thickness of 1.3 ± 0.2 mm and can stretch up to 100% in all directions. This allows it to maintain flexibility under temperature fluctuations or vibrations. The material is rust-proof, waterproof, and radon-resistant—ensuring long-term durability in demanding construction environments.
