The residential wing has been built to CSH Level 4 and the non-residential area to a BREEAM ‘Very Good’ rating. Phil Goffin of Brown Smith Baker explained, “We wanted an air barrier/VCL to meet a minimum vapour resistance of 250 MN/sg provided by Wallint 50. It was installed on the warm side of rafters behind plaster stops in conjunction with Klober’s Pasto Sealant and Permo TR Tape. Pipe work penetrations were sealed using the Solar-Line Sealing Collar.
