  BU369 Fitting tolerances

BU369.jpgAccurate fitting tolerances and construction methods ensure that a building element will always fit into the opening or space it is meant to without compromising the performance.

Often, however, insufficient consideration is given to tolerances during building design, and the builder is usually not provided with enough information on acceptable fitting tolerances for the given project.

This bulletin, written primarily for designers, provides basic guidance on:

  • the function of tolerances
  • how to determine acceptable tolerances
  • avoiding potential problems during design
  • avoiding problems on site.
