BBA certificates for the VMZINC ‘Compact roof using cellular glass insulation’ and ‘Structural roof using PIR or mineral board insulation’ have been updated and extended. The compact roof utilises Foamglas® cellular glass insulation to prevent the passage of water vapour and is therefore ideal for buildings with a high vapour drive such as swimming pools. Both systems are installed without mechanical fixings penetrating the insulation, thus greatly reducing scope for thermal bridging. VMZINC remains the only zinc manufacturer to have such accreditation and can additionally offer a BRE Green Guide A+ rating for the structural roof system.
