The safety and flammability of polyurethane foam — expert opinions on the product.

Polyurethane foam — safety

The most-common material selected for insulation is PUR foam. This foam’s safety is a significant factor in that choice — this quality is important, both during the application itself and in a later period. Experts agree that it is worth choosing a reliable team with experience and knowledge of the OHS guidelines applicable to performing polyurethane-foam insulation using the spray method. The safety of the foam use is high (foam fire-behaviour class E or F). The product is self-extinguishing.  This means that after cutting off the heat source, the foam extinguishes itself. Thanks to its physical properties, depending on the type, it can be used both indoors and outdoors.

Polyurethane foam — flammability

The flammability of polyurethane foam is not a factor that discourages the use of such material as insulation. Apart from the foam-flammability factor, its non-toxicity is also important. Polyurethane foam does not constitute a hazard in toxicological terms — the foam is odourless and non-toxic, so is widely used.

 The foam combines with materials of different physical and chemical properties. Although we encounter polyurethane foam in our daily lives, we often forget about that fact. The versatility of polyurethane foam is hard to underestimate. No wonder it is used for insulation, and, in the case of the most-complex designs, PUR foam is used with the spray method.
