Rendered Rainscreen Cladding

ProWall Rainscreen Cladding is an external envelope system specifically developed to allow a stable rendered finish on timber frame developments. ProWall overcomes the problems of frame movement with a ventilated and drained cavity.

Rendered rainscreen cladding maintains a healthy quality of air as it allows the building to breathe, while providing protection from the elements.
