Sisalation® foil products should be installed in accordance with AS/NZS 4200.2:1994 Pliable building membranes and underlays – Installation Requirements for Metal Roofs, Tile Roofs and Walls.
It should be installed with the antiglare face out and a 150mm overlap between runs. External cladding should be installed without delay. For System R-Value calculations using Sisalation® Tile Roof products go to www.insulation.com.au/fletcherspecpro In roof applications Sisalation® Tile Roof Sarking should also be installed under the battens and maintain a 40mm sag from roof tiles to ensure the durability and function of the product through its lifespan.
Foil products conduct electricity. It is important that safety is followed when installing this foil product. As a minimum have your electrician disconnect the electrical supply prior to installation to ensure that the foil is not ‘LIVE’. Reconnect the electrical supply after installation with a test to confirm that the foil is not conducting electricity.
Under no circumstances should this foil product be applied horizontally in residential ceiling space and under floor. Refer to the Australian / New Zealand Wiring Rules (AS/NZS 3000:2007) for more detailed information.
Important Notes: Prior to and during installation Sisalation® foil products must be kept dry and out of contact with alkaline products, cement and mortar. Sisalation® foil products are not designed to withstand weathering and external cladding should be applied without delay.

Residential buildings: They are suitable for application on both timber and steel framed buildings. Commercial buildings: They are not suitable for and should never be installed under metal roofs.
How Sisalation® Works
With a large surface area exposed to the sun, the roof area is the largest contributor to heat gain. Roofing materials (tiles and metal sheets) are often poor reflectors, potentially emitting 90% of heat gain into the ceiling space. With roof temperatures reaching upwards of 80°C, ceiling space temperatures can reach a whopping 54°C.
Correctly installed Sisalation® can:
• Significantly reduce ceiling space temperatures;
• Reduce heat transfer into the attic space, which reduces heat into living spaces;
• Reduce heat loads on attic ducts and equipment;
• Reduce ceiling temperatures and heat gain.
Radiant surface temperatures of walls and ceilings have a direct influence on interior comfort levels and energy costs. Using the benefits of aluminium foil, Sisalation® reflects 95% of radiant heat and emits only 5%.
A single layer of Sisalation®, combined with an adjacent air-space provides thermal resistance equivalent to a wall 7 bricks thick!
Sisalation® not only insulates your home, but protects it from rain driven water infiltration. Sisalation® also limits dust from entering your building by sealing off draughts in the walls and roof space.
Make sure your family stays cooler and more comfortable at home. Sisalation® reduces heat transfer through the envelope of a building. Where there’s a temperature difference, heat flows naturally from a warmer to a cooler space.
To maintain comfort in colder months, the heat lost must be replaced by the heating system. Sisalation® minimises radiant heat from escaping through the walls and roof by acting as a thermal barrier.
