Isolripa for past under roof.

This system Isolripa ® saves economical costs of energy and propitiates a good interior climate of the houses.

The roofing system of ISOLRIPA ® consists of slats and beams in prestressed concrete, mortar and molded expanded polystyrene.
The coefficients of thermal transmission calculation, obtained through the method prescribed in ISO 6946:2007, roofing ISOLRIPA ® are 0.44 W / m ° C and 0.42 W / m ° C, respectively for a heat flow upward or downward, assuming that the materials are dry. To obtain these values should be applied a reinforcing thermally insulating material at the base of the joist when the cover separates spaces working environment outside, to reduce the risk of condensation. This reinforcement consists of applying a sheet of molded polystyrene (EPS60) with 50mm thick and 200mm wide.
If not choose the reinforcement system (only advisable when the space area is not useful), the values of heat transfer calculation will be 0.78 W / m ° C and 0.66 W / m ° C, respectively for a heat flow upward or descending, admitting that the materials are dry.
