chimney sealing systems

What ever form of heating you use an efficient chimney is essential for your health, safety and economy

Thermocrete Sealant is applied by a high pressure rotating spray machine.

The sealant fills all the gaps and cracks leaving a smooth gas tight coating on the inner surface.

The above values are expected to be achieved under laboratory test procedures.
Site results can be expected to vary from these figures. Therefore the above results do not constitute a specification.

Thermocrete Chimney Linings are committed to a program of expansion and development and in the interests of progress we retain the right to alter the above specifications at any time.
