The dangers of a faulty chimney

Whatever form of heating you use - coal, gas, oil, log-burning, etc. an efficient chimney flue is essential to you for both economy and health. Inadequate insulation causes condensation, which combines with the fumes to produce sulphuric acid. This attacks the brickwork, eating into the mortar resulting in dangerous joint leakage, eventually leading to the total collapse of the chimney stack.

Thermocrete is the answer

Thermocrete is a revolutionary process which allows your existing chimney to be re-lined without any constructional work. The material used for this is Thermocrete 82 a lightweight but incredibly strong monolithic refractory castable. It will restore your chimney stack to perfect condition (making it stronger than new), completely curing existing damage and preventing further deterioration. Thermocrete is impervious to flue gases and acid attack; it also has excellent insulation properties.

How the Thermocrete chimney lining system works

The basic concept of the system is simple but extremely effective. A rubber former is inserted precisely in position through the entire length of the flue. Special techniques are used to keep the former centralised, even if the flue has a 45° bend. Thermocrete 82 material is pumped into the flue from the top of the chimney stack filling all voids, cracks and damaged joints. When the Thermocrete has hardened, the former is deflated and removed leaving a perfectly smooth cylindrical flue.

Each flue is isolated

The Thermocrete System allows each appliance to operate with its own correct sized flue within one chimney stack. This is essential in instances where appliances use different types of fuel.

Industrial applications

Industrial flues serving boilers up to 1.5 million BTU have been lined with Thermocrete. The principal is exactly the same, with the pouring process being repeated in stages until the full height of the chimney is reached.

All Thermocrete linings are installed to:
European standard BS EN 1443 1999 and B.S. 6461 complying to the building regulations 1985 England and Wales and the building standards for Scotland 1981 to 1984.
