	FOAM-IN-PLACE CAVITY WALL INSULATION
	** NOTE TO SPECIFIER ** NCFI Polyurethanes; Foamed-In-Place Building Insulating, Roofing Systems and Specialty Insulation products. This section is based on the products of NCFI Polyurethanes, which is located at: Mount Airy Industrial Park P. O. Box 1528 Mount Airy, NC 27030-1528 Toll Free Tel: 800-346-8229 Tel: 336-789-9161 Email: emillie.lee@ncfi.net Web: www.insulquiet.com [ Click Here ] for additional information. NCFI formulates and manufactures foam-in-place polyurethane foam systems. NCFI nationally sells and services foam mixing and dispensing equipment providing end-users with one source for their foam needs. NCFI was organized in 1964 by Dr. H.W. Bradley, a research chemist, and Barnhardt Manufacturing Company, a leading manufacturer of fiber cushioning materials whose founding dates back to 1900. Soon after its organization, NCFI had earned a reputation as a quality manufacturer of flexible polyurethane foam for the bedding and furniture industry. In 1967, NCFI began formulating foam-in-place systems for insulating cold storage buildings. NCFI expanded the product line with development of highly successful systems for roofing applications, multiple types of commercial and residential insulation, taxidermy, specialty moldings, and marine applications. NCFI provides equipment and application training, engineering expertise for specifications and designs, and a professionally trained contractor base for spray foam applications. NCFI's R&D center, with full development and testing capabilities, is unique among spray polyurethane foam systems suppliers in the United States. This specification includes our continuous InsulBloc® seamless spray polyurethane foam insulation (SPF) system which is a highly versatile, closed-cell, spray-in-place foam insulation with outstanding air barrier and moisture barrier qualities that is ideal for masonry walls like the ones found in educational institutions. And since it's seamless, InsulBloc is an excellent barrier to dust, drafts, pollen, and noise pollution.
