Stamisol Extreme BI

Thermal protection for concrete against summer overheating & winter frost

Effectively protect your concrete structures with Stamisol Extreme BI, a dual-function insulating mat designed to optimize the curing phase: it reduces thermal expansion in summer and frost risk in winter, while preserving the moisture required for proper hardening.

Lightweight and flexible, it is easy to handle on site. Its insulating performance (U-value improved by 65% compared to standard mats) ensures optimal thermal and moisture regulation.

Insulation, mechanical strength & durability

Stamisol Extreme BI is made of a PVC-coated polyester support (1,500 g/m²) with a thickness of 7.5 mm.

It offers high tensile strength (2,500/1,500 N/5 cm) and excellent tear resistance (1,300/900 N/5 cm). Its lightweight structure provides effective thermal insulation (λ = 0.045 W/m·K, R = 0.154 m²·K/W) during curing, in both summer and winter.

The right balance between performance and on-site practicality

Choose long-lasting performance with a solution that delivers excellent climate protection and strong mechanical stability, while remaining easy to handle for installation teams.

Reusable, it reduces waste, simplifies handling, and complies with SIA 262 requirements for continuous concrete casting.
