We are converting a barn in Normandy and have made it to the living room stage succesfully. Now looking to install a Deville www.deville.fr/) woodburner, following the example of a French neighbour - but now need to install a chimney flue. Have found a number of companies in the UK selling insulated steel flues for about £80 - £100 per metre. My neigbour has the French equivelant but as a contractor fitted it he is not sure where it comes from. Does anyone know a French Manufacturer or retailer? What is the sytem called in French?
