Sheffield Vermiculite Insulation 100l

This loose-fill insulation is supplied in a 100-litre bag containing ultra-lightweight vermiculite granules. It is suitable for use in lofts, cavity walls, and chimney flue linings, where its free-flowing nature helps achieve full coverage over irregular surfaces and hard-to-reach spaces without the need for cutting or shaping.

Typically, it is poured directly over loft floors or between joists to form a continuous thermal barrier. The material is also used to insulate around pipes, electrical cables, or within voids and cavities, helping to enhance energy efficiency and reduce unwanted air movement on site.
