Most existing homes and other structures are filled with fiberglass insulation that is very inexpensive, so it keeps the initial building costs down. It actually ends up costing the owner more money, because fiberglass rarely stops air leaks efficiently. Additionally, the material has a low R value and absorb moisture so it is prone to unhealthy mold and mildew. Spray foam insulation will stop the air leaks which will save you money on your utility bills. It also has a very high R value of eight for each inch. Fiberglass only has a R value of one for each inch.
