Cover is 72sqm per 60 metre roll

Sisalation roofing foil consists of outer layers of aluminium foil bonded to weave, bonded together with a heavy coating of flame retardant adhesive. It is installed under metal roofs, it reflects radiant heat and provides a barrier to prevent condensation on the underside of the roof sheet.

 Alumimium reflective foil insulation is also referred to as "sarking"


Flame retardant Sisalation is suitable for use in buildings in bushfire prone areas. Provides an effective barrier against moisture, vapours, wind, heat and dust penetration when overlapped.


When used in conjunction with an airspace, Sisalation is an effective thermal insulation material because of the high reflectivity and low emissivity of its aluminum foil surfaces. Complies with the requirements of AS/NZS4859.1. The contribution of this product to Total R-value depends on installation and environmental conditions which include the effect of dust.



Installation Sisalation should be installed in accordance with AS/NZS4200.2:1994 for the installation requirements for "Pliable Building Membranes". External cladding should be installed without delay. Reflective foil in roofs must be installed with a sag or drape down of approximately 40mm - 75mm between the rafters or battens.  This is to allow a vapour barrier to occur between the reflective foil and the metal roof sheeting. To achieve the stated total R-Values, a mimimum air space of 40mm is required adjacent to each reflective foil face.


Condensation : How it occurs!

The underside of a roof often provides conditions under which condensation of water vapour will occur. In cooler weather, roofs can become several degrees cooler than the outside air temparature. As a result, the air in the roof space may be cooled by contact with the roof. This depression of temparature is often sufficent to cause condensation as air is cooled, it's ability to hold water vapour dimishes. The amount of condensation will depend on the amount of water vapour in the air and this varies with climatic conditions.  Flat roofs are more prone to condensation than steep or pitched roofs. Roofing foil insulation provides a heat and vapour barrier and also provides a separation membrain to reduce friction between the roof sheets and the supports, due to expansion and contraction of the roofing material.
