Installation

Note:hardboard cladding should be kept dry and clean before installation.

Flashing material should be fixed to the frame before the hardboard cladding is fixed. This should be done in accordance with best industry practice.

Sheet hardboard is fixed in the same manner as plywood cladding. Internal corners can be detailed using a timber stop, or the planks can be cut and scribed to match the splay of the plank on the adjacent wall. External corners can be detailed using either a timber stop or a manufacturer's pre-formed metal corner.

Fixings should be in accordance with manufacturers' recommendations and to best industry practice.

Five diagrams showing hardboard fixings to studs. Four of these show fixings at internal and external corners, using scribed cuts, timber stops or pre-formed metal corners. In each case flashing or sarking is used between the corner and the stud. The fifth diagram shows the plank nailed to the stud and the plank below in a lap minimum 20 mm.
