The roof of the distillery building is like a sandwich with a lower liner sheet, a vapour control layer (VCL), high performance insulation and finally an anodised aluminium cladding. The lower liner sheet works and VCL are already well underway.

Kalzip who are supplying the cladding have already formed all of the sheets, each uniquely curved to match the geometry of the roof. The Kalzip system uses 96% recycled aluminium in it cladding system sheeting and recycled glass bottles in its insulation, and what is installed can be recycled at the end of its design life.
