May 30, 20233 yr 1 hour ago, ETC said: https://nhbc-standards.co.uk/2020/6-superstructure-excluding-roofs/6-1-external-masonry-walls/6-1-18-wall-ties/ That NHBC guidance is incorrect as it does not include Note 3 from Table 5 of Approved Document A, which refers to cavities of over 175mm (of which this is) and a requirement for 125mm or 62.5mm embedment in each wall. Ancon have an easier to read version here and the full version is here on Page 23.
