Timber frame wall ties

25 August, 2020

Timber frame wall ties are structural connectors designed to join the timber frame of a building to its external masonry or brickwork. The use of wall ties is a critical aspect of timber frame construction, as it helps to prevent structural damage due to differential movement between the timber frame and the masonry or brickwork.

In the United Kingdom, the Building Regulations Approved Document A requires that wall ties be installed in accordance with BS EN 845-1:2013, which provides guidelines for the design and installation of wall ties for use with masonry construction. The standard specifies requirements for the materials, dimensions, and corrosion protection of wall ties, as well as the spacing and orientation of ties along the wall.

The selection of wall ties is dependent on several factors, including the type of masonry or brickwork, the location of the building, and the environmental conditions.

Vista offers three types of timber frame wall ties; the V61 Timber Frame Tie, the Helical Tie and the V62 High Movement Timber Frame Tie. Each of these ties conform to BS5268-6: 1:1996. These wall ties are specifically designed to secure an inner timber frame to an outer brick skin while absorbing substantial vertical movement between the brick and timber, all while performing their structural function.
