Abstract
A fastener for joining insulation blocks to a wall of a refrigerator or cold storage chamber. The fastener is provided with a central flat back which is fastened by means of nails or the like to a concrete or other rigid wall. The fastener is also provided with a plurality of thin in-line spikes at each side of the central flat back and projecting outwardly therefrom in two parallel lines. The spikes are then preferably covered with an adhesive and an insulation block pressed onto the adhesive covered spikes. The adhesive seals the spike opening into the insulation block resulting in maximum insulation and a perfect and secure holding of the insulation block to the rigid wall. The elongated thin spikes are preferably undercut at their inner ends to act as barbs in the more secure holding of the spikes within the insulation block.
