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.

60 Years of Durability

This seamless rendered cladding has a 60-year BBA certificate for durability and delivers first-class performance concerning fire, strength, weather tightness and stability.

Rendered rainscreen cladding maintains a healthy air quality as it allows the building to breathe while protecting from the elements.
