Behind the Wall, Where Performance Actually Lives
The facade gets noticed. What’s inside the wall determines whether the building actually performs, fire separation, acoustic comfort, moisture management and how fast the building can close in during construction. CSP Architectural’s plasterboard range covers both ends of that story: the rigid air barrier that closes a building in before external cladding is finished, and the complete internal plasterboard and framing system that finishes the job from the inside out.
Both product lines come from Siniat, an Etex Group brand and one of Australia’s leading manufacturers of interior and exterior drywall systems.
Siniat Weather Defence™

Rigid Air Barrier vs Internal Lining - Different Jobs, Same Wall
Siniat Weather Defence™
Outside the frame
Fixed to the exterior face of the structural frame, behind the external cladding. Its job is to make the building weathertight during construction and to contribute to the fire and thermal performance of the completed wall assembly. It is not visible in the finished building and is not painted or decorated.
CSP Plasterboard - Siniat
Inside the frame
The internal lining and framing system on the room side of the wall — what gets painted, what carries fire and acoustic ratings between rooms and tenancies, and what supports fixtures, fittings and finishes inside the building.
