Twin Wall Rigid

Twin Wall Insulated Flue System

If you don't have a chimney, we can create one for you. The simplest, most cost effective solution is to install an insulated twin wall chimney system, (subject to survey).

Twin wall insulated flue pipe is a double skinned flue that is approved by HETAS and is suitable for constructing internal flue systems suitable for wood burning and multifuel stoves.

Twinwall can be installed internally, rising up through the building and out of the roof. A false chimney breast can be constructed to conceal some of the flue pipe if you would rather not see too much of it internally. Flue pipe in upstairs rooms can be boxed in to conceal.

Another important use for Twinwall flue is in Thatched properties where it can be dangerous to use a flexible liner. Flexible liners can rest against chimney bends causing possible "hotspots" and if this happens to be near the thatch, it can be a fire risk. Rigid liner installations ensure that the flue pipe is straight and will not cause heat transference to any part of the chimney brickwork or roofing material.

The chimney system must be installed to comply with Document J of the Building Regulations in England and Wales, as well as to the flue manufacturer’s installation instructions.
