The short answer is that the upfront cost of foam insulation is more expensive than fiberglass and cellulose insulation. However, due to fiberglass and cellulose’s inefficiencies and the wear tear on HVAC units over time, they are the more expensive options for home insulation.
Foam insulation is an entirely different way to seal a home and keep “bought air” inside the house and the outside temperatures out. It is a lot different than fiberglass insulation and cellulose insulation. Neither fiberglass nor cellulose insulations seal up the wall or joist cavities, and air and heat can more easily permeate the fiberglass and cellulose. When air and heat permeate, your money is leaving the house – or as my marketing guys say, “Your house is leaking money.”
Our foams are specialized chemicals that mix at the end of our tools’ nozzles and fill in all of the spaces and voids that the fiberglass and cellulose can’t fill. In other words, we can pack more insulating material into the same area as the other insulations, so indeed, there is a higher upfront cost than fiberglass and cellulose insulation.
Some comparisons show injection foam and spray foam can be about two times higher than blown-in cellulose and fiberglass, but remember – we are packing more product into the same cavity.
