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.
