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.
