Twin Wall Systems UK, 316/904 Grade Stainless Steel | Yorkshire-Chimneys

This type of flue would be can be used used as a liner or to form a new chimney in a property that has no chimney. Effectively we would build a Chimney either on the inside or outside of your Property. This is made up of two layers of 316/904 Grade stainless steel with a 25mm void filled with Rockwool or insulation. This is a HETAS approved Chimney product and is manufactured under ISO9001 and has been tested to BSEN 1856 – 1: 2003


Fitting a twin wall insulated flue can mean we can install a stove pretty much anywhere in your home, even in a conservatory or by adding an electric fan, even in areas where running a flue is not possible.

We have many testimonials and before and after pictures to provide on request of these sort of installations.
