How to choose suitable Purios foam?

Depending on location and surface where you want to use Purios fame insulation, a suitable foam type should be chosen. For external insulation of places particularly exposed to humidity use closed-cell foam. However open-cell foam is best for attics. On walls use foam of lower density, while harder foam with higher density is better for floors.
