THERMOCRETE is a revolutionary process which allows your existing chimney to be lined without any construction work.
The material used for this is THERMOCRETE B2C a lightweight, but incredibly strong Monolithic Refractory Castable, reinforced with Ceramic Fibres. It will restore your chimney-stack to perfect condition (making it stronger than new), ensuring the flue is correctly sized for the appliance, increasing the flues efficiency, completely curing the existing damage and preventing further deterioration.
THERMOCRETE is impervious to combustion gasses and acid attack and 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 B2c 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.
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.
Benefits of the Thermocrete System
Thermocrete B2C is guaranteed for 25 years.
It is suitable for both class I and II appliances, gas and solid fuel.
Thermocrete B2C allows your chimney to be lined from outside without disturbing the fabric of the building.
It reinforces your chimney and prevents further deterioration.
