Thermal Shim
ACS Thermal Shims reduce the effects of thermal bridging through stainless steel masonry support when used with concrete or steel framing, helping to improve the energy efficiency of the building. Thermal Shims are used predominantly with ACS Masonry Support Systems.

Installation and Best Practice
ACS Thermal Shims must be installed so the bracket is fully bearing on the shim, particularly at the heel of the bracket, to maintain the strength of the system and ensure compressive forces are transferred back to the structure while the system remains thermally isolated. The maximum allowable thickness of all shims should not exceed the outside diameter of the fixing, typically 12mm on ACS masonry support systems. Where more than one shim is required, the total number should be kept to a minimum to avoid creating slip planes that could allow settlement or creep under load.
