Condensation and the aquatic room

The room or shed in which the pool is located is much more prone to condensation than any other room in the house. Indeed, during the inter-seasons and in winter in particular, the air in the aquatic area is warmer than the outside air. Furthermore, by the very nature of the place, the air is saturated with humidity. All the elements are brought together so that condensation in indoor swimming pools takes hold over the long term. If nothing is done to limit or control the level of humidity in the air, it can quickly become a recurring problem for the structure of the building and the health of bathers.
