I'm waiting for information on the cellulose blown-in insulation. Meanwhile, if this space has to be sprinklered, would it be practical as it is packed with insulation?

Mineral Wool, i.e. thermafiber and roxul are common non combustible. Watch the details the code requires non combustible not fire retardent. Cellulose Blown-In Insulation is a wood fiber based fire-retardant but not non combustible. Also some fiberglass insulation, i.e. no kraft facing and no plastic reinforcement stranding is also non combustible. Had a project a few years back that used the infill technique to avoid suppression in concealed combustible spaces. The inspection included selected borings through the sub floor to assure proper fill. Hope that helps John Drucker Jr CET Fire Protection Subcode Official Fire/Building/Electrical Inspector Borough of Red Bank, NJ -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of A.P.Silva Sent: Wednesday, April 21, 2010 1:11 PM To: [email protected] Subject: Cellulose Fibre Insulation I have a 14" deep open web wood truss floor space filled with "blown Cellufibre sound attenuation insulation". Anyone know whether this insulation is "non-combustible" complying with a combustible concealed space permitted by NFPA to be unsprinklered? They claim the insulation is fire retardant. But I'm not sure.
