BDA Certification
Our Spray Foam Insulation System has successfully passed strenuous testing by the BDA 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 BDA testing facility. In addition to conclusive hygrothermal and condensation risk analysis testing. Following this was a rigorous in-house re-training of all accredited contractors. Our spray foam passed the above tests because of lower water absorption, higher vapour resistance and certified breathability.
