AbstractUsers of cellulose fibre insulation (CFI) have two basic concerns: whether the insulation will provide the desired thermal resistance over the life of the building, and whether its use will constitute a health hazard or contribute to the deterioration of the building. Thermal resistance is primarily a function of thickness. CFI, however, is prone to settlement so the thickness will depend on the initial or blown density and the settled or design density. This note examines the precision of various methods used to determine design density. This is important in order to assist the contractor in determining the amount of CFI required for an installation and to ensure that the long term R-value of the CFI is as required.
