Calcium Silicate Boards

Calcium silicate board is an asbestos-free thermal insulation product that can withstand continuous high operating temperatures. It is a light weight, low thermal conductive, high strength, easy to install, reliable and durable product. Industrial grade piping and equipment insulation is often fabricated from calcium silicate. It is a white free-flowing powder obtained by reacting calcium oxide and silica. It has a low bulk density and high physical water absorption.

Calcium Silicate Boards are manufactured from a mixture of Portland cement, fine silica, special cellulose fibers and selected fillers to impart durability, toughness and moisture resistance. Calcium Silicate Sheet is then cured by an autoclaving process whereby the ingredients are reacted together under heated steam and high pressure.

The synthetic cement silicate binder provides exceptional dimensional stability and an unrivalled resistance to movement due to effects of moisture or heat. Calcium Silicate Board does not contain any ingredients or free alkali that could be dissolved by moisture or condensation. If exposed to moisture, the board will completely recover on drying out, with no permanent loss of strength.

Calcium silicate boards are used in Europe as a highly successful fireproofing material. High performance calcium silicate boards retain their excellent dimensional stability even in damp and humid conditions and can be installed at an early stage in the construction program, before wet trades are completed and the building is weather-tight. Most Calcium Silicate boards are classified as non-combustible according to EN 13501-1 (2007).

Calcium Silicate boards will not degrade with time and within normal applications, the life of the product is limited only by the durability of the supporting structure and materials used in fastening. Calcium Silicate Board will not rot or support fungal growth and is unaffected by sunlight or steam. Calcium Silicate boards are designed for use in applications, where impact resistance, fireproofing, waterproofing, sound adsorption and heat isolation are required.
