Metal Wall Tie

Description

Several wall ties were recovered from the location of the hostels. These wall ties were made from twisted cast iron, split and flattened at each end. They were approximately 16cm (6.3 inch) in length and the metal itself was 3mm thick. These wall ties would have been used between the cavity of the double course external walls for the purpose of bonding these together. It is known from the architectural records that these external walls were 11 inches thick (Calgarth house plan c.1942). The use of cavity walling within the buildings of the Calgarth estate set them apart from the standard range of prefabricated buildings constructed during the 1940s. Their solid brick construction would have provided additional insulation and comfort to the residents.
