VENTED CAVITY SYSTEMS
Vented cavity systems
Thin coat render system onto render board on vented cavity system
The BRE recommend a drained and ventilated cavity. A drained and ventilated cavity offers a second line of defence against driving rain penetrating through cracks in the render. The top hat sections and other associated products will create a cavity behind a render system thus allowing air to circulate horizontally and vertically. The wall will then be able to breathe and remove any build up of moisture. A two part vented corner post and base rail are optional extras that are available for finishing around the edges of the system. These sections are manufactured from galvanized steel and are available in two standard widths.
