The Protect range of Reflective Technology construction
membranes utilises high purity aluminium foil to provide low emissivity, radiant
barriers. When installed facing into an unventilated airspace (as defined in BS
EN ISO 6946), they effectively block infra-red radiation and enhance the
thermal performance of the airspace. This, in turn, improves the overall
thermal resistance of the wall construction, providing design flexibility and
cost savings when achieving these more onerous U-value targets.
