Did you know that the choice of the insulation material can have knock-on effects on the whole building structure?

Taking as an example a building with a steel deck flat roof, the steel structure can be about 15 t lighter in moderate and Mediterranean climates when the PU solution is used rather than the heaviest solution. The difference is 13 t for the cold climate. This gain of about 10 % is due to the fact that the insulation layer of the PU roof weighs only 10.7 t compared to 86.7 t for the heaviest insulation layer (moderate climate).
