Perfect for homes without a chimney (an increasingly common occurrence). Insulated twinwall is essentially a prefabricated chimney consisting of a pipe within a pipe and insulation between them. You can connect into the twinwall flue pipe using single wall stove pipe from the appliance, or twinwall straight out of the appliance and run either through the wall or straight up through the roof, in which case you will require roof flashing to seal the opening.
We have a selection of different systems available to suit different requirements, and a multitude of different lengths, bends, tees, adapters and supports.
