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 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.

Chimney Lining for Wood Burning Stoves

Chimney Lining systems for wood burning stoves and open fires. If you’re looking to install a wood burning stove or a multi fuel stove, due to new regulations it is necessary to have the chimney relined. The Thermocrete liner is there to ensure safe usage of your stove by preventing carbon monoxide leaking into other areas of the property. Another main advantage of lining is to increase the performance and efficiency of the flue and will also prevent the build of tar within the flue which is a potential fire hazard. A wood stove or multi fuel stove can be up to 80% efficient in comparison to open fires which might be as low as 20%. Thermocrete install flue liners suitable for all types of wood burning stoves.
