Vapour Control Layer

A vapour control layer lapped and sealed should be used below the insulation Board. When using fully adhered systems, board joints should be taped subject to adhesive system being used.

Bonded Boards

The insulation boards are embedded in a layer of bitumen on a 3G type felt to BS EN 13707: 2013 (Flexible sheets for waterproofing. Reinforced bitumen sheets for roof waterproofing that has been adhered to the deck. Unilin recommend that all systems should have mechanical fixings included or be adhered using other suitable adhesive).
