Roof Sarking (Sisalation)

Roof Sarking is a key component of any roof space. It is manufactured in 4 specific grading’s, light, medium, heavy duty and extra heavy duty. Roof Sarking is often referred to as Sisalation which is a Fletcher branded product range. The job specification will determine the duty because some difficult jobs may require a more durable foil. The reflective properties of each duty are exactly the same.

Eureka can specifically cut to length to suit your precise job requirements. This means that there is no wastage, nor the additional costs that go with standard rolls.

Roof Sarking (Sisalation) Insulation Benefits

Typically used under metal roofs and bonded to an insulation blanket for commercial and retail applications, Roof Sarking is also widely found under tiled roofs in residential applications. The benefits are very broad including:

  • Waterproofing under both tiled and metal roofs.
  • Prevents dust, dirt and leaves entering the roof space.
  • Prevents drafts that may occur in tiled roofs.
  • Assist with energy efficiency in keeping heat out and warmth in.
