Durability Performance

The SIPCO BBA certificates states that structural insulated panels have a durability comparable to that of OSB/3 to BS EN 300:2006.  Therefore, provided the installation remains weathertight, a life of at least 60 years may be expected for SIPS. 

Additional information can be found within the Structural Timber Association SIPS Technical Bulletin 5 and SIPS Pocket Guide.  The SIPCO BBA Certificate provides further information on protection of the building and long-term maintenance and repair requirements.
