The Seldek Twin Wall chimney system provides a high quality and robust chimney with high thermal performance. The system consists of straight lengths, bends, support components and fittings which are constructed entirely from stainless steel and a nominal 30mm mineral wool insulated annulus. The chimney system has a polished stainless steel finish as standard but there is also the option of having the system powder coated black, which is becoming more and more popular.
The system is push fit with locking bands to secure each joint. The system may be installed internally or externally. The relatively low external wall temperature permits installation with only a 50mm (2") air gap clearance to combustible materials which is particularly useful in internal installations passing through ceilings.
The liners we use for all our chimney lining work are from the Schiedel TecnoFlex range of flexible flue and chimney liners which have been designed for lining an existing flue or chimney.
TecnoFlex Plus is a twin skin flexible chimney liner designed for gas, oil and multi-fuel, where the maximum flue gas temperature does not exceed 600°C and has a diameter range 80 – 300mm although we only use these liners in multi fuel applications.
