Fire Tests of Polyurethane Foam Roof Deck Construction on Steel Decks.
Abstract:
Fire tests were conducted on built-up roof assemblies specified by the Navy consisting of spray-applied polyurethane foamed plastic covered with specified elastomeric coatings. The Standard UL 790 entitled Tests for Fire Resistance of Roof Covering Materials, was utilized to measure the resistance to fire originating from sources outside a building on which they may be installed. As a result of these fire tests and comparisons with previous results for other assemblies, three candidate systems are eligible for Underwirters Laboratories Inc.s Classification and Follow-Up Service as Fire Classified Roof Deck Constructions.
