Manufactured from recyclable co-polymer polypropylene, the stong corrugated board replaces concrete backing bloacks a a rate of 1 sheet of Cav-Form to 9 concrete blocks. Supplied in 2000mm x 450mm sheets, the board is light to handle and easy to install. In fact, unlike 9 concrete blocks, you can lift a sheet of Cav-Form between your finger and thumb. The board is placed in front of the Cavity Forming Spacer in between rows of cavity ties. It protects the cavity from mortar and debris during constuctions and from water ingress after construction.
Stone, brick, concrete block and timber are all absorbent materials and draw moisture (including rainwater and water vapour from the atmosphere) into the outer leaf. It is imperative that this moisture does not travel any further. The cavity is the essential moisture barrier, preventing the inner leaf from becoming damp. Any mortar or debris dropped into the cavity during construction can seriously affect its function by settling on the wall ties or collecting at the base of the cavity, resulting in moisture and cold bridging. The system also provides added protection to properties exposed to driven rain.
