ABSTRACT:
The invention is concerned with a retainer for holding a sheet of insulation against a metal plate and with the method of seating a sheet of insulation against a metallic plate. The retainer comprises a linearly extending member made of a hard but deformable material and having a flange extending outwardly adjacent a first end thereof to sit against a first side of a metal plate with the remainder of the member extending through a hole in the plate and a bore extending longitudinally in the member from the first end thereof towards a second end thereof, the bore terminating at a chamber of larger orthogonal dimension than the bore itself, the chamber terminating short of the second end of the member. Also part of the retainer is a rod fitting within and extending outwardly from the bore and having at a first end thereof a head of larger orthogonal dimension than the bore, the head fitting within the chamber. Generally the rod includes a weak portion which is easily breakable. Also a part of the retainer is a stud projecting longitudinally from the member. A cap also generally forms a part of the retainer, the cap binding to the stud after the insulation is pushed over the stud to hold the insulation in place.
