The ACS Double Leaf System consists of four horizontal wires with welded cross wires. The design of the DL System allows for use in cavity walls. The DL system ensures correct positioning of ties at 450mm centres. In addition, it complies with BS 5628: Part 2: for reinforcement masonry. In walls consisting of two parallel leaves with up to a 75mm cavity, the DL system provides structural reinforcement.
It provides the same benefits as the DLC system as it also eliminates the need to use and lift heavy blocks.
