The recommended material for use as Sarking is a Reflective Foil Laminate, which provides weatherproofing as well as insulation. It has a high reflection and low emission factors for low temperature radiation found within buildings. The Reflective Foil Laminate is a flexible sheet material, which is supplied as a roll. It is installed over the rafters, under the tile battens and has many benefits to offer when used under the roof covering. Sarking reflective foil insulation material should be a double sided. Using reflective foil laminate as a Sarking material is recommended because of its excellent insulating and weatherproofing properties. It has excellent water proofing qualities and when installed properly prevents damage occurring to ceiling materials and interior fixtures and fittings. Sarking eliminates dust intrusion and reduces sound penetration. It also helps prevent fire, from an outside source, igniting inside the roof space. Its use is highly recommended in buildings, which are located in high-risk bush fire areas. When wind gusts occur, Sarking reduces the impact of uplift forces on the roof tiles.

Valleys:

When working on a Sarked roof, it is important to note that the Sarking material must not be laid into the valley gutter. A tile batten should be fixed along each side of the valley board around 15 mm away from the board. The Sarking membrane should then be turned over around the batten. When there is a change of pitch between two roofs, Sarking should be fixed to the lower roof if it has a pitch of less than the minimum requirements. Under these circumstances the Sarking under the lower roof must extend at least 350 mm into the higher pitched main roof. The Sarking should be fixed to the lowest batten of the upper roof section and continue over the whole of the lower section. Where Sarking is also to be fixed on the upper part of the roof, the overlap to the lower roof section should be at least 150 mm.

Anti-flap pads:

During times of high wind, Sarking can move causing increased noise levels. If a roof is likely to be subjected to high winds then consideration should be given to the use of security pads. These pads are made of a light foam rubber material and are fitted when the Sarking is fixed in place. The pads are placed under the tile battens between each rafter, at every Sarking lap joint. In all applications where Sarking is installed, Harmony Roof Tiles includes the use of anti-flap pads.
