Sisalation or Sarking


Sarking is the sheet material which can be put over the roof trusses before the final roof covering is installed.

It’s normally standard on a metal roof as it prevents condensation on the underside of a roof from dropping onto the ceiling below.

In the case of a tiled roof it helps with weatherproofing and keeps dust out of the roof space.

In bushfire zones it is mandatory for a tiled roof to have sarking.

The reflective sarking (installed reflective side facing down) does help in reducing summer heat being radiated into the roof space and can help to keep the house warmer in winter. (See Reflective Finishes for more information)

In addition to plain sarking you can get an insulation blanket with sarking attached. This offering some sound insulation, for rainfall, and extra thermal insulation.
