Thermoseal Roof Sarking

What is Roof Sarking?

Thermoseal™ roof sarking is A Protective Second Skin™ installed under tiles to minimise weather-related water damage such as wind-driven rain entering the roof cavity. If rain enters the roof it can wet insulation, making it less effective, and cause ceiling staining in plasterboard. It also reflects up to 97% of radiant heat making your home more comfortable during summer and winter.
