Grease DuctsGrease ducts are best protected with 8 lb. density insulation proven that offers uncompromised thermal heat resistance over lesser 6 lb. density blankets. (Click here for more density related information.) Single layer compressed joints or double layer with staggered seams CL4FIRE grease duct systems provide additional value and space savings over gypsum shaft installations. CL4FIRE systems are designed and tested to ULC standards to keep internal grease fires from getting out and external fires from getting in. Canadian made and Canadian Tested for increased safety. |
