Sarking is a pliable membrane that sits under your roof sheets, like a protective second skin. It helps insulation work more efficiently, and protects the things you value from storm driven rain and dust, condensation and bush fire ember attack.
It is installed under your roof sheets in sections parallel to the eaves with an overlap between each layer. This helps prevent storm driven rain from getting into your roof space, which if left untreated, can lead to unseen mould growth or even worse, ceiling staining or permanent damage. It also reduces draughts in the roof space, which helps insulation to work better and limits dust entering the home through gaps around down lights and vents.
On one side, Thermoseal has a distinctive green anti-glare surface and on the other side, a reflective silver foil. When the reflective side is installed facing into the roof cavity, it creates an air gap R-Value – a resistance to radiant heat – that slows the transfer of the heat so that your insulation can work more efficiently and your home can feel even more comfortable.
Thermoseal is developed and laminated in Australia using flame retardant adhesives to ensure compliance to BAL bush fire ember attack requirements, in accordance with AS3959.
