Roof Sarking

$95.90

Roof sarking is a protective second skin under your roof, installed when building a house, doing home extensions, a home renovation or roof restoration.

Roof sarking is a pliable laminated membrane that is positioned under your roof during installation by the builder and is rolled out in sections either parallel or perpendicular to the eaves with an overlap between each layer.

Roof sarking will protect the frame of your house from the weather during construction. When your home is completed, sarking will protect your roof cavity from storm driven rain and dust, improve its thermal performance, help it resist bushfire ember attack and reduce the risk of harmful condensation.

Non-Permeable Roof Sarking

Thermoseal reflective foil roof sarking is a non-permeable, vapour barrier product designed to reduce the transmission of moisture into the home and contribute a reflective air gap R-Value to the roof system when positioned to adjacent to an inward or outward facing air cavity.

These products are recommended for use in warmer climates where they provide insulation against radiant heat and reduce the flow of water vapour from the outside environment into the home*

Key product features:

  • Improves the R-Value of the roof system by contributing a reflective air-gap R-Value – this can be up to RT1.8 (summer heat flow down down)
  • Reduces the transmission of water vapour through the building structure*
  • Improves energy efficiency by reducing draughts allowing insulation to work more effectively
  • Protects the building frame from decay by reducing the entry of wind driven rain and dust.

How Thermoseal Roof Sarking Works

Thermoseal Roof Sarking - like a safety blanket for your house

A simple way to understand how reflective foil laminate membranes like Thermoseal work, is to compare them to a survival blanket.
The silver foil blanket helps regulate temperature, whilst at the same time providing protection from hot or cold weather, particularly where additional protection from wind and rain is also required.

Likewise, reflective foil sarking products can shield up to 95% of radiant heat away from the roof cavity space.

Thermoseal works under your roof tiles, like a protective second skin, helping make your home more comfortable and protecting the things you value from the weather.
