Wall ties are important components that link the inner and outer walls of a hollow wall, also known as leaves, or hold a masonry wall to a structural frame. Wall ties have been utilised since the early twentieth century, with considerable changes in form and materials to satisfy current building regulations.
In this blog, we go through the different types of wall ties available.
Types of Wall Ties
Cavity Wall Ties
Cavity wall ties are used in buildings with cavity walls, which have a gap between the inner and outer leaves. These ties help maintain the structural connection and stability between the two leaves.
Cavity wall ties are typically made of metal and are designed to span the gap between the two leaves, providing a secure connection. Common materials include stainless steel, which offers excellent resistance to corrosion, and galvanized steel, which is more cost-effective but less durable in harsh environments.
Veneer Wall Ties
Veneer wall ties are used to attach a brick veneer to a structural backing, such as wood or steel framing. These ties are designed to allow for differential movement between the veneer and the backing, preventing cracks and structural issues.
Corrugated Ties
These are flexible and allow for differential movement between the veneer and backing.
Z-Ties
Z-shaped ties that provide a strong connection while accommodating movement.
Adjustable Ties
These allow for adjustments during installation to ensure a secure fit.
Cavity Wall Ties
Wire Ties
These are simple and cost-effective, made from twisted wires.
Sheet Metal Ties
Flat ties made from sheet metal, provide good strength and stability.
Bar Ties
Strong and durable, these ties are made from metal bars and are used in high-stress applications.
The installation of cavity wall ties involves placing them at regular intervals in the mortar joints of both leaves during construction. Proper placement and spacing are crucial for the ties to function correctly.
