A chimney in a multi -storey building should be of high quality.
The one who has a fireplace in the apartment of a multi -storey building probably faced a situation when smoke does not go outside, but creeps around the room. This situation is associated with the formation of reverse traction in the fireplace, which can occur for various reasons, for example, in the absence of wind or during the rain. But it can be caused by the technical malfunctions of the chimney itself. Therefore, it is especially important that the chimney in the multi -storey building is fulfilled in strict accordance with all the requirements of the norms and standards.
