There is a material which helps maintain our buildings warm in the winter and cool in the summer; from stadiums to hospitals, from cold stores to residential houses, from floor to ceiling, it can be found everywhere. And in our battle against climate change, it is one of our most important weapons! Nowadays, PIR thermal insulation is the most efficient generally used insulation material. It is light, easy to manage and install, and its low thermal conductivity property means that, in comparison with other insulation materials, a much thinner layer of it is sufficient to achieve the same energy efficiency. PIR is extremely versatile, applicable almost everywhere, as thermal insulation of roofs, terraces, floors and window frames, or even as retrofit insulation for residential houses.
