Twin wall insulated flue: Ideally used if you don’t have a chimney, or going through a wall or ceiling. Twin wall is a layer of stainless steel pipe with 25mm of insulation and another layer of pipe. All solid fuel, wood burning and oil appliances will need twin wall flue if you are planning to use a stove in an area with no existing masonry chimney. We would highly recommend that you contact one of our staff who would gladly talk you through the options available.
