Table 23 (’Properties of roof underlays and building wraps‘). Install the wall underlay directly over the framing. Install the cavity battens directly over the wall underlay as described in Cavity battens on page 9. No additional wall underlay is needed between the wall cladding and the cavity battens except in the following situations.
