Siniat Weather Defence Building Boards
Siniat Weather Defence is an external sheathing board coated with water-repellent materials to provide excellent weather protection, thermal efficiency and airtightness. Its gypsum core gives the board enhanced resistance to moisture, fire and sound. Perfect for external insulation and finishing systems, Weather Defence is a cost-effective solution that’s dimensionally stable and mould resistant. It’s easy to install and can be cut using the ‘score and snap’ method, producing no dust or flying fragments and generating less waste. Suitable for use with steel infill panels, full light steel framing, timber and concrete structures, Siniat Weather Defence holds double BBA certification and is fully A1 non-combustible, meeting requirements for buildings over 18 metres.
