The ACS 2000 range wall tie is a multi purpose cavity wall tie designed to exceed the requirements of a type 1 wall tie as specified in BS EN 845-1: 2003. This wall tie is capable of achieving the loads required of a type 1 wall tie due to its high sectional properties and specially designed embedment features at each end of the wall tie.The tie is resistant to water crossing a cavity due to the integrated ‘drip’ features that serves to prevent the transgression of water from the outer leaf to the inner leaf of a building even when installed with an angle of up to 5° in an unfavourable direction. The minimum mortar joint thickness for which this tie is intended for use is 10mm.
Installation & Best Practice
Wall ties should typically be installed at a density of at least 2.5 ties/m2 for walls in which both leaves are thicker than 90mm. This can be achieved by spacing the wall ties at 900mm horizontal centres and 450mm vertical centres, staggered at alternate courses.
Wall ties should be evenly distributed over a wall except around openings or at an un-bonded panel edge where the tie density should be increased to 225mm vertical centres within 225mm of the opening or edge.
The length of the wall tie should be sufficient to allow an embedment of at least 62.5mm meaning that the minimum embedment of 50mm is always achieved after allowing for site tolerances.
