Floor Insulation TN


Floor Insulation TN

The optimal insulation must be equal to or greater than the U value calculated for the insulation of the walls and ceiling of the cell, considering that the ground temperature varies from 12 ° C to 16 ° C according to the areas. Isocold, calculated the optimal thickness for the insulation, divides the thickness in order to lay a single / double staggered path of closed cell polyurethane/extruded or expanded polystyrene insulating sheets, with fire reaction in Euroclass E or better, with CE marking compliant with UNI EN 13164 standard, with Environmental Declaration EPD / LCA and Climate Declaration.

The provision of an effective vapor barrier to the outside of the insulation, finished with properly sealed joints, is of the utmost importance, since the water vapor that penetrates the insulation would compromise its characteristics.
To prevent this type of destruction of the insulation of the cold room, it is necessary to provide a vapor barrier on the warm side of the insulation. This vapor barrier must be complete and cover the entire floor. It should be remembered that water vapor is a gas and is not sufficient only to make the external surface waterproof; overlapping joints must be sealed.

The choice of insulation is very important as it represents a large part of the total construction cost. Insulation material and thickness are also important for the energy consumption rate. In addition to a satisfactory coefficient of thermal conductivity, the insulation material should also be odor-free, anti-rot, pesticide and impermeable to water vapor.

During the reinforcement and casting of the floor, it is necessary to be very careful not to pierce the insulation protection barrier and not to place loads on the insulation in order to deform or damage the floor. In addition, it is necessary to make sure that the barrier is turned over the surface of the panel so as not to let the water from the casting pass through, all these precautions are necessary to avoid any problem of insulation or swelling of the floor.
