Unlike traditional blanket insulation, foam completely seals any cracks and gaps in the surface you’ve placed it on. One of the core properties of expanding foam insulation is that it’s capable of getting into every nook and cranny. But what does that mean for its acoustic value? Can Spray Foam Insulation Reduce Noise? Since the material isn’t fibrous, it should be decently resistant to mold growth. Unlike most batt products, hardened foam insulation will never lose its insulating properties or sag. Once the spray insulation sets, it’s there to stay. Just look for insulation that uses HFO compounds as blowing agents - or opt for closed-cell foam instead. Still, if that’s something you’re worried about, you can always use an alternative with a lower climate impact. Since that gas has a high impact on the climate, most “green” construction projects steer clear from that kind of insulation. Notably, open-cell foam insulation has carbon dioxide as the blowing agent, the compound that makes the solution foamy. All these ingredients are necessary to create the reaction that propels the polyurethane, making it foam up, expand, and harden. The “B” side of the mixture contains polyols, which are needed to create PU, as well as a catalyst, blowing agent, flame retardant, and surfactant. One of the components contains isocyanates in the form of MDI and pMDI.

Nowadays, professional spray foam insulation comes to construction sites in two separate containers, allowing the crew to mix it on the spot. Though PU was first synthesized in the late 1930s, it wasn’t used for insulation purposes until the 70s. In essence, spray foam insulation is made of polyurethane (PU, for short), a polymer of several organic compounds.
