Abstract
A washer, for use with a fastener for attaching a slab of insulation and a covering mesh to a substrate, has fingers which automatically partially block its entry aperture when the fastener is tightened so that a finish applied over the washer does not fill the cavity of the washer. This reduces the conduction of heat through the insulation by way of the finish material and the fastener. It also provides an undercut surface for improved adhesion of the finish material to the washer.
