Loose Fill Insulation - The Vermiculite Association

Loose Fill Insulation

The enhancement of the fire ratings and acoustic performance of the pores and cavities of masonry construction and hollow blockwork can be achieved by filling it with exfoliated vermiculite treated with a water repellent.

Larger grades of exfoliated vermiculite can be used to insulate lofts and attics. Vermiculite has the benefit of being easy to use with application consisting of pouring it between the joists and then leveling.
