Vertical DPC
The vertical DPC should be wrapped around the
cavity batten or closer, then across the outside face
of the SureCav panel . Ensure the additional frame-
tie is fixed within 225mm of the opening (see below
regarding additional wall-ties). The solid timber-
frame allows the ties to be fixed in any position.

Cavity batten
Trim the SureCav sheet up to, or overlapping the
cavity batten by 10mm or so, if desired. The
trimmed sheet can be fixed to the cavity batten, but 225mm max.
it is not essential. The SureCav joining strip must be
trimmed to meet the cavity batten to ensure the Silicon in
overlapping part of the sheet does not interfere with
corners
the external masonry.

Addition wall ties

This procedure will prevent slots having to be made in the SureCav sheet on each course of
block-work when building away from a doorway or window reveal.

It is recommended that an additional wall-tie is included within 225mm of the opening on each
board coarse level to satisfy the structural requirements.
The ties should then be fitted every 450mm vertically coinciding with the joint in the SureCav
sheet.
