Abstract In a channel specially designed to fasten semi-rigid mineral fibre in- sulation to masonry walls, it is known to be constructed from 20 gauge galvanized steel or other suitable material. The channel is designed to have pre-punched holes along its length for fastening of the channel to the masonry wall. The top portion of the channel is knurled to allow easy entry of the drywall screw. The unique feature of the channel are the teeth running along its length which are pressed into the surface of the butted together sections of the insulation providing a strong grip between the two adjacent pieces of insulation. Of prime importance to the success of this system is the recent technological advancements of the mineral fibre itself which allows the teeth of the channel to engage the insulation fully and hold without mechanical support rather than be repelled or pushed back by the inherent nature of the insulation material. After the insulation is secured to the masonry wall by concrete nail fastening systems, the drywall is screwed to the channel.
