Vermiculite Insulating Cement

Lightweight cement made with exfoliated vermiculite ultra-lightweight aggregate. This material is about 20% of the weight of normal cement mixes and 25 mm of this material is equivalent to 500mm of normal cement in insulation value. Classed as a non-combustible material for the purpose of the building regulations, Vermiculite Insulating Cement is ideal for any area where a low density, high insulation and non-combustible material is required. It is especially useful for filling the space between firebacks and fireplaces or behind Victorian Type cast-iron fireplaces. It can also be used underneath and over the top of outdoor pizza ovens and bread ovens. The material is not for use where abrasion resistance is required. Supplied as a dry mix – just add water and mix for a short time.
