According to his analyzes, one can exclude a concern for infiltration. It is therefore a condensation problem. And it is due to the very structure of the building, poorly isolated: “We end up with concrete sails (vertical concrete walls, editor’s note). There may be a small insulation in it, but hey, these are sails that are 10 to 15 cm. And which give directly inward, explains the expert. So we can quite imagine that when it is cold, the concrete surfaces that are inside are frozen. And so here it is, it’s like when you rub your glasses and blows, it makes fog. It’s exactly the same phenomenon: hot air on a cold surface, it condenses. ” It is a classic phenomenon, called thermal bridges.
Often, they tell us that they are at five, ten minutes a day. But that is not enough.
These thermal bridges, Dynamic Immo does not deny their existence. The agency is both trustee of the building and manager of part of the rooms. Because in Louvain-la-Neuve, we buy by room. In a community at the Walloons Tour, there can therefore be up to eight different owners or managers. Including Dynamic Immo, therefore, which manages around fifty rooms. So we wanted to discuss with them the condition of the rooms we had visited.
Thibaut Koenigsfeld, manager, recognizes that there are thermal bridges and tells us that, if the student warns in time, cleaning costs are almost never imputed to him. But according to him, the phenomenon of condensation could be reduced if the students are more so: “Often, they tell us that they are at five, ten minutes a day and that is enough. Unfortunately, in this type of accommodation in addition with new chassis, that is not enough, it is necessary to ventilate much more. “ An observation which is not completely shared by Jean Simonis. According to him, ventilating is not enough: “With thermal bridges like that, even if we have a rate constant interior humidity of 50%, we will have condensation phenomena.”
