Siniat Weather Defence, External Rigid Air Barrier Board
Siniat Weather Defence is a fire resistant external sheathing board (RAB board) which has transformed building envelope construction and performance. Weather Defence is made from gypsum and uses patented hydrophobic core and water resistant liner. It is a replacement for traditional weather barriers such as fibre cement, galvanised sheeting, or combustible sarking membranes that do not meet the performance provisions.
