Best way to insulate an attic.
Attic insulation cellulose vs spray foam.
Cellulose insulation is the oldest material used in home.
The big disadvantage with spray foam is cost.
Cellulose vs fiberglass vs spray foam.
It s generally 3 to 4 times what you ll pay for blown cellulose or fiberglass.
It is the most expensive option with costs running as high as two or three times as much as fiberglass batts or cellulose loose fill.
That s why whenever cellulose is blown into a sealed framing bay stud rafter joist etc it should be dense packed.
Dense packed cellulose will not settle.
While cellulose insulation costs less closed cell spray foam provides a superior seal will save you more energy in less time.
As part of our ongoing mission to educate our customers we are here to discuss the best insulation for attics and the pros and cons that go along with each insulation type.
Depending on the region and market spray foam insulation can sell for 1 30 to 3 50 per square foot.
Cellulose insulation is probably the safest among all the other kinds of insulation there is including spray foam insulation.
Cellulose insulation is also one of the most affordable and energy efficient insulation technologies on the market.
Other than the fact that it s an insulator cellulose can also reduce the noise heard between rooms.
Cellulose for attic insulation.
Spray foam insulation drawbacks.
In most home markets this type of insulation is considered an added home value that will pay.
If you don t have hvac and ducts in the attic spray foam on the roofline isn t really necessary.
Cellulose averages up to 32 savings over fiberglass and it is cheap to produce and transport.
Spray foam provides the highest r value while open cell spray foam has about an r value of 2 2 to 3 5 per inch closed cell spray foam has about 6 7 per inch.
If the hvac equipment and air ducts are in your attic it is better to install spray foam insulation specifically with open cell spray foam to protect the equipment and ducts.
You won t have any problem with it being accidentally exposed as it s not harmful at all.
Foam does not provide for complete insulation needs and does not address heat loss gain via convention through framing members.
Spray foam if you were to look at a pie chart showing what you spend every year on home energy use your heating and cooling system would take up nearly half of the pie.
But with properly installed insulation you can cut down on your energy demand leading to a lower heating and cooling bill and creating a more comfortable.
Pro noise reduction.

I d blow insulation on the attic floor after air sealing of course.
