Fairview announces the official launch of Siniat Weather Defence – a fully non-combustible Euroclass A1 rated sheathing board designed to suit most building facades.
Siniat Weather Defence is a lightweight external gypsum sheathing board with condensation management properties for building envelope construction. The product is deemed non-combustible in accordance with C1.9e (i) and (iii) and can be installed on frame for up to 12 months’ construction exposure.
Compared to cement particle boards of the same thickness, Siniat is 30% lighter. Resistant to mould, rain and moisture, Siniat Weather Defence acts as a breather membrane, while also making the building watertight for internal trades.
