Weather Defence® Rigid Plasterboard

Siniat Weather Defence® is an award-winning, rigid air barrier which is used behind facade cladding systems to regulate indoor environment.

Weather Defence® is suitable for enclosing a building to provide a solid weathertight barrier that forms part of the external facade system. Due to the high vapour permeability of weather defence, moisture can escape from the wall cavity when used with a vented or ventilated facade system, this controls the risk
of condensation build-up causing damage within wall spaces.
