25/14 Restraint System (PDF, 3.73 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, stainless steel Ancon SD25 or basalt fibre Teplo-BF-CT 25 wall ties can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork.
These fixings are available for a combined backing board and insulation thickness of up to 220mm. They can be installed directly through the insulation when using any thickness of rigid insulation or when using ROCKWOOL Rainscreen Duo Slab®, Isover Polterm Max Plus, Kingspan Facades K-Roc Rainscreen Slab, Knauf Insulation Rocksilk® Rainscreen Slab, Xtratherm Stonewool and ROCKWOOL Nyrock® Rainscreen 032 with a maximum thickness of 180mm. When using more flexible insulation materials up to 220mm thick, an Ancon Compression Sleeve is required around the fixing screws.

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 us 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 UKCA and CE marked.
