Answer: keep a minimum safety distance (8 cm to 15 cm).

A quick reminder beforehand: casing must be carried out over the entire length of the duct; it is forbidden to tub only part of the duct. If this conduit crosses a floor, the point to be observed is to keep a minimum safety distance between the external face of the conduit and any combustible material. This distance depends on the thermal resistance of the pipe (there are several categories) and the temperature of the combustion products. As a general rule, it is estimated that the minimum distance between the external face of the duct and the floor should not be less than eight centimeters. But depending on the case, this minimum distance can go up to fifteen centimeters. Be sure to respect these standards in force, at the risk of not being compensated by your insurer in the event of a claim. You too, send us your brico question
