Vented insulation for nail based applications

Abstract

A vented insulator for use in nail based construction. A sheet insulator includes a base having integrally formed thereon a plurality of upwardly extending nodes of uniform size. The nodes are uniformly distributed across the length and width of the base forming a plurality of air ventilation channels.
