PropertiesFire protection
Floor/ceiling assemblies using the Hambro system have been tested by independent laboratories. Fire resistance ratings have been issued by Underwriters Laboratories Inc. in the United States (UL), and by Underwriters Laboratories Inc. of Canada (ULC) covering gypsum board, acoustical tile and spray-on protection systems. Reference to these published listings should be made in detailing ceiling construction. Check your UL or ULC directory for the latest updating of these listings. | | | |
