Design Considerations

When selecting a connector to use there are many factors which should be considered, these include timbers, loadings, masonry leaf width, cavity size, height of building, type of building and geographical location. It is the responsibility of the Building Designer to ensure the correct product is used for each application.

There are numerous standards and documents which offer guidance on wall tie usage and these should be considered before making a decision, these include:
