Loose-fill Insulation

Light weight Thermo-floc is less than half the weight of cellulose fibre insulation. Spontaneous ceiling collapse is highly unlikely with Thermo-Floc®

Hydrophobic Thermo-floc® will not attract water or moisture. Cellulose fibre insulation is hygroscopic and will attract and absorb water, adding further weight ontop of your ceiling.
