Roof Sarking is robust, durable and reinforced material designed for use under residential and commercial roofs. It acts as an effective secondary skin for the roof, protects it from wind-driven rain, draughts, condensation and improves the performance of insulation.

Roof sarking boosts the performance and comfort by providing the following benefits:

  • Protects your home from unseen mould growth, ceiling staining or permanent damage.
  • Limits the dust entering the home through gaps around downlights and vents
  • Reduces draughts that blow dust into the roof space
  • Improves thermal performance by reducing heat flow
  • Helps manage the risk of condensation
