Describes the procedures to be followed for the installation of reflective foil laminate in domestic, commercial or industrial buildings. It covers the use of the material as a sarking membrane under tile, metal deck or corrugated sheet roofs, and as a vapour barrier or thermal insulation (or both) over ceilings, in walls and gables, and under floors. Sarking procedures for roofs of both rafter and purlin construction are described, together with treatment at eaves, ridges, and valleys. The various uses of the material are illustrated.
