This was the first time we have completed insulated fabric structure enclosures. This meant considerable R&D within our factory to work out a way to fix the insulation between two PVC membranes, being the outer and liner roofs. Our overall steel frame design also had to be compatible with using conventional ‘insulated’ wall cladding systems like Kingspan panels and double glazed aluminium joinery in order to provide the insulation R value that was requested by the client which presented a challenge in itself.
