The CTE sets different parameters to establish both thermal and acoustic insulation, which vary depending on the application and characteristics of the work. IRPEN S.A.U.'s Cellular Polycarbonate Systems meet the requirements required for facades.

An example of this are several buildings built (schools, sports centers, houses, etc.) in which a double polycarbonate skin has been used for their enclosure. In the Energy Saving and Energy Demand Limitation Regulations for enclosures, the CTE sets the Thermal requirements based on:

-Determination of the climate zone from tabulated values or from climate records

-Thermal transmittance, depending on the type of enclosure: if it is in contact with outside air, if it is in contact with the ground, interior partitions in contact with non-habitable spaces, openings and skylights.

-The total thermal resistance of a building element consisting of homogeneous and heterogeneous layers.

-Condensation: Our panels alone have Thermal Transmittance values that can reach up to 0.71 W/m2K (panel R 2560-12). If a double skin is made, we can achieve even lower Thermal Transmittance values, an example of which is our façade at the Colegio de Torrejón de Ardoz, thus meeting the requirements of the CTE with regard to Thermal Transmittance in all areas.
