Foam insulation whether it s in the form of foam board sheets or spray on insulation requires a smaller amount of material to achieve the same amount of insulation.
Which insulation is better fiberglass or foam.
Building pros of course know better.
Fiberglass insulation vs spray foam insulation comparison.
Fiberglass insulation is significantly cheaper than spray foam insulation but it is also less effective especially in extremely cold conditions.
Few construction topics bore homebuyers more than insulation.
Fiberglass installation labor cost is about 1 00 to 2 75 per square foot based on the amount of insulation and the location.
Fiberglass is the less expensive choice for wall insulation and is the simplest to install which makes it an ideal choice for homes in four season climates.
Comparing fiberglass to foam.
You re well aware that heating and cooling account for roughly half of the energy used in the average home.
And you also know that properly insulating a home helps homeowners save money and makes houses more comfortable.
For example insulating a 10 square foot wall area to r 15 costs about 3 40 to 4 00 with fiberglass insulation while a comparable r value for rigid foam costs roughly 10.
Spray foam insulation for both types starts at about 1 50 per square foot and can cost more than 5 00 per square foot when a thick application is applied.
A thicker application of fiberglass however can prove to be a bit more efficient.
