Spray foam insulation can occasionally contract. However, there is a chance that the insulation in this product will start to shrink over time, which will lessen its insulating capabilities.

Spray foam insulation has an estimated life expectancy that varies from 80 up to 100 years. And that can be achieved with little to no maintenance at all. The material is strong and it can last for as long as your building can. Different from cellulose and fiberglass, spray foam does not deteriorate, sag, or settle.

The manufacturing costs of spray foam insulation are higher than those of other insulation products. The raw chemical materials are more expensive than recycled cellulose or glass fibers. Chemical processing facilities are more expensive to build and maintain, with stricter safety protocols and testing protocols.

The finished product of spray foam insulation is safe if it was installed correctly. The only hazards or risks it can pose are during the application process when the chemical reaction happens. The residents are not there during that process, and the contractors wear personal protective equipment for safety.
