Installation

Over rafter: Roll out SFNC SuperFOIL over rafters. Staple at least 500mm or as conditions dictate and cover joints with SuperFOIL reinforced tape, overlap widths 75mm (min 50mm, max 100mm).

At the eaves cut SuperFOIL around the rafters and seal to cavity wall insulation or wall plate to create airtight envelope.

Fix battens parallel with the rafters and apply breathable roof underlay according to manufacture guidelines.

Fix roofing battens and tiles according to manufacturers guidelines.

Under rafter : Roll out SuperFOIL, starting along the top of the roof. Batten horizontally over rafters. Staple at least 500mm or as conditions dictate and cover joints with SuperFOIL reinforced tape, overlap widths 75mm (min 50mm, max 100mm).

At the bottom of the roof pitch, staple the SFNC SuperFOIL directly onto the timber wall plate to create airtight envelope. Fix battens across the rafters and ensure air gap between SuperFOIL and the plasterboard.
