The reflective aluminium surface should face an internal air cavity where possible to maximise radiant heat reflection. All joints should be overlapped and sealed using appropriate vapour control tapes to maintain airtightness. Service penetrations should also be sealed. Note – this VCL is not self adhesive and requires mechanically fixing.
