Abstract:
An attachment implement for attaching an insulation panel to an underlying structural substrate, comprising:a washer plate member, having a predetermined diametrical extent defined around a central axis, for engaging an outer surface portion of an insulation panel to be secured to an underlying structural substrate; and a body portion integrally connected to a substantially axial central region of said washer plate member, wherein said body portion has a substantially inverted, rounded domed-shaped configuration defined by radiused external surface regions circumferentially symmetrical around said central axis for uniformly distributing the compressive forces, attendant the mounting of the insulation panel upon the underlying structural substrate, in a radially outwardly direction, and for engaging the insulation panel so as to be capable of compressing the insulation panel without damaging the same by otherwise axially concentrated forces.
