Surface Fixed Channels
Plain-backed channels can be surface-fixed to steel, concrete and in some instances, masonry.
The Ancon channels suitable for surface fixing are 36/8, 25/14, 28/15, 38/17, 41/27, 40/25, 49/30 and 54/33.
25/14 Restraint System
The Ancon 25/14 restraint system is designed to tie masonry to steel, timber or concrete frames through a layer of insulation.
25/14 Channel is supplied in lengths of 2700 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.
Once the channel is installed, Ancon _ _25 wall ties, typically SD25, can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork.
See technical literature for product references and fixing centres for both ties and screws. Contact us for information when fixing to timber.
Concrete Fixing Screws
Screws are available to accommodate a combined backing board and insulation thickness of up to 267mm. A 6mm pilot hole is required. An Ancon Stainless Steel Compression Sleeve, the same depth as the insulation, is required. More information, including wall tie and screw spacings, is available in Ancon’s 25/14 Restraint System datasheet.
