This means that you can cover walls and ceilings more efficiently without doing too much work.
Is spray foam insulation better.
The four most important factors when choosing an insulation material for your home are r value soundproofing safety and cost.
The attic roofline is typically insulated with 5 nominal fill foam resulting in an r value close to 20.
Even though it was far more expensive they noted that it performs much better.
And because it can insulate a house more effectively you won t have to spend as much on.
Unlike other kinds of insulation like cellulose spray foam provides better insulation because its fluid nature allows for it to go through tiny crevices.
Spray foam insulation vs.
A spray insulation is referred to open cell or closed cell because of the difference between the small bubbles cells that make up the foam.
Any spaces and gaps that aren t filled can equate to the size of a basketball with enough air leakage everyday to fill two air blimps.
However if your attic doesn t have any hvac equipment or air ducts you.
Closed cell spray foam insulation has the lowest noise deadening ratings.
Spray foam insulation has less market share but is increasing in popularity.
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.
Fiberglass traditional insulation comes in primarily two forms.
It s hard to perfectly install fiberglass and cellulose.
Open cell polyurethane spray foam performs better with noise reduction and comparable to fiberglass batten insulation.
Spray foam is the better choice when it comes to long term cost and thermal resistance.
This makes the foam a softer more flexable material.
Spray foam expands up to 100 times its original size to fill every corner of your home s envelope for thermal insulation and air sealing.
As you can see from the comparison table spray foam is not the best material for sound insulation.
Cellulose for attic insulation.
