Design and Installation

Cavities up to 100mm wide require wall ties at maximum 900mm horizontal centres and 450mm vertical centres, with additional ties around openings and at corners. Cavities wider than 100mm may require ties at reduced centres. Wall ties must slope down from the inner leaf in order to shed water into the cavity.
