By 1979, Kornbleet founded Payless Insulation, which specialized in servicing existing homes (attics, walls, and floors). The business grew, and in 1986 Kornbleet became a licensed installer of K-13, a cellulose product applied with a spray adhesive. By 1989, Payless Insulation was offering fireproofing and insulation removal services. The company started distributing Bonded Logic's Ultra Touch cotton insulation products in 1999.
Payless Insulation recently started manufacturing patented cotton insulated semi-flex air ducts called Superior Air Ducts. Bonded Logic makes the cotton in these new ducts only for Payless. Kornbleet described the product as a new generation of environmentally friendly, sturdy, higher-efficiency ductwork.
