Mineral & synthetic insulation
Description
Le Flocon 3 is a loose-fill stone wool intended for hand spreading with a rake in unoccupied loft spaces. It is aimed at small or hard-to-reach jobs where using a blowing machine is not an option: the loose wool is spread by hand and then levelled to the target thickness. The declared thermal conductivity λ is 0.037 W/(m·K), for a density of 50 kg/m³. The material is non-combustible, Euroclass A1 for reaction to fire, and carries an A indoor air emissions rating. It is packaged in 15 kg bags, eighteen bags per pallet. The ROCKWOOL installation guide for hand spreading sets out the thicknesses to be achieved and the depth markers to be fitted before the work is handed over.
