25/14 Restraint System (PDF, 1.28 MB)
The Ancon 25/14 system is designed to tie brickwork to steel, including SFS studwork.
Self-drilling high-thread screws fix through the channel and the insulation, into the steel. Once the channel is installed, Ancon SD25 wall ties can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork.
This system is suitable for use with a maximum combined insulation and backing board thickness of 220mm. When using rigid insulation board up to a depth of 220mm and Isover Polterm Max Plus, Kingspan Facades K-Roc Rainscreen Slab, Knauf Insulation Earthwool RainScreen Slab and ROCKWOOL Rainscreen Duo Slab up to 180mm, Ancon high-thread fixing screws can be used without a Compression Sleeve. When using other thicknesses of these insulations or other semi-rigid/flexible insulations, an Ancon Compression Sleeve (the same depth as the insulation) should be used around the fixing screws to provide the necessary support.
25/14 channel is supplied in lengths of 2700mm and 3000mm, and features pre-punched holes at close centres to ensure a fixing position is always located near the end, even when it is cut on site.
See technical literature for wall tie/screw references and vertical fixing centres.
The channel has a 16mm opening to easily accommodate a drive socket and washer for the fixing screws. This system has been independently tested and is CE marked.
We recommend SD25 wall ties are designed to achieve an embedment of 55mm in the outer leaf of brickwork. They are available in lengths from 100mm to 300mm to suit open cavities up to 259mm.

From January 1st 2021, the UK will recognise both the EU CE marking approvals, for a time limited period, and the new UK based approval system, which will be known as the UKCA mark. The EU will only recognise CE marking by EU notified bodies as proof of efficacy moving forwards. Leviat has been working closely with both EU notified and UK approved bodies to ensure compliance is achieved at the earliest possible opportunity and we can confirm that we have obtained all relevant certification.
