Heatproof Mortars & Cements

Vitcas Heatproof Mortars and Cements range consists of superior quality mortars and screed, which are resistant to high temperatures. They act as a protective rendering on fire bricks and are used for making replacement fire bricks in stoves, fireplaces and wood fired ovens.

Heatproof Mortar

Heat resistant mortars are materials that are mainly used for making joints in the construction of fire bricks. They have lower adhesion than traditional mortars, therefore their quality is extremely important as the durability of the structure depends on it. In this category, you will find a wide selection of heatproof mortars that will work in places exposed to high temperatures reaching up to 1860°C. They are perfect for the construction of fireplaces, pizza ovens, barbecues or smokehouses and for the renovation of flues and pipes.

Vitcas refractory mortars can be used in industrial applications to seal ceramic fibre boards and ceramic fibre blankets. The mortars are delivered as ready-made mixtures (just add water and mix well) or ready-mixed mortars with a consistency suitable for trowel or filler application. 

Heat resistant Cement

Vitcas Vermiculite Insulating Cement is made of expanded vermiculite, which gives it refractory properties and also makes it 20% lighter than standard cement. It is used for filling gaps between firebacks and fireplaces, cast iron fireplaces and outdoor bread and pizza ovens. It is supplied as a dry mix that is ready to use after adding water and mixing.
