| THERMAL CONDUCTIVITY vs COEFFICIENT OF THERMAL TRANSMITION: STRUCT-CRYO of density 35 Kg/m3 has a thermal conductivity of 0.024 W/mK (watt per meter and per temperature's grade), whereas for the polystyrene conductivity goes from 0.035 to 0.045 W/mK, depending on polystyrene type. Those values are different from the Coefficient ofThermal Transmitting Point (watt per square meter and per temperature grade). The Coefficient refers just to the final construction, not to the foam. HOW TO REACH THE SAME COEFFICIENT OF THERMAL TRANSMITION: Example: ifa customeruses: Styropor: - conductivity: 0.040 W/mK - thickness: 80 mm - coefficient ofthermal transmition: 0.35 W/m2K Using STRUCT-CRYO you would need less thickness to reach the same coefficient thermal transmitting point. HOW TO CALCULATE THE CORRECT STRUCT-CRYO THICKNESS REQUIRED Example: to substitute Styropor for STRUCT-CRYO 35, we would need a thickness of: 80 x (0.024/0.040) = 48 mm Then is enough use 48 mm ofSTRUCT-CRYO 35 Kg/m3 to obtain the same coefficient ofthermal transmition when using 80 mm of Styropor. |
