Steel water and central heating pipes are generally placed and concreted in grooves cut into the walls. However, we should insulate them with special lagging made of polyurethane foam. This way we will avoid excessive heat losses, especially then, when the installation is carried out in unheated rooms. In the case of cold water pipes, we protect ourselves against condensation in places on the wall, inside which pipes run. It is also worth insulating installations made of other materials with insulation.
