BBA Certification

The Icynene Spray Foam Insulation System has successfully passed strenuous testing by the BBA for direct application to breathable roof membranes with a single tiling/slating batten.
This process involved practical applications to a variety of roof structures at the BBA testing facility in Watford in addition to conclusive hygrothermal and condensation risk analysis testing. Following this was a rigorous in-house re-training of all accredited Icynene contractors. Icynene passed the above tests because of lower water absorption, higher vapour resistance and certified breathability.

Icynene is fully tested and approved by BBA for use in construction
