For semi-rigid/flexible insulations, we recommend compression sleeves are used which correspond to the thickness of the insulation specified. The tubes are designed to ensure that the compressive strength and stability of the channel tie system are both achieved and maintained by preventing the channel deflecting into and compressing the insulation during installation, and whilst under normal load.
25/14 Brick Tie channel System is available in lengths of 2700mm and 3000mm. It 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. The channel has a 16mm opening to easily accommodate a drive socket and washer for the fixing screws.
Wall ties are available in various lengths to suit open cavities from 35mm to 259mm (see selection table). They are located in the channel by rotating through 90 and can be easily moved to the required position where they are built into the masonry bed joint. See tables for correct tie references and fixing centres.
