Ancon 25/14 Restraint System

Product datasheets are available to aid specification of the Ancon 25/14 system.

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.

This system is also suitable for use with timber and concrete frames, contact Ancon for details.

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.

Ancon recommends 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.
