Blown Cellulose Insulation Vs Blown Fiberglass Insulation Attic

Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass.

Blown cellulose insulation vs blown fiberglass insulation attic.

When comparing blown in insulation both fiberglass and cellulose are nearly identical in price both costing around 0 70 to 0 80 per square foot for 6 inches of insulation. How are they similar and how are they different from blown fiberglass vs. Cellulose produces much less static than fiberglass. At 3 5 per inch of material the r value of blown in cellulose is 23 better per inch than fiberglass batts.

The higher the r value the more efficient it is. Cellulose is easier to keep out of bird blocks and air conditioner condensate pans. Assuming your current attic insulation is made from fiberglass and has a value of r 13 you d have to add roughly 10 inches of additional fiberglass to hit r 38. The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass.

Making cellulose a better choice for homes in northern climates. With that said most homeowners agree that blown cellulose is slightly more efficient due to the face that it blocks more air than fiberglass. You can get to the same place with either material. You can find high r value insulation produced in both fiberglass and blown cellulose.

Fiberglass batts however are less expensive costing on average 0 30 to 0 40 a square foot for 6 inches of insulation. Installation costs for blown in insulation costs around 2 a square foot where installation costs for batts is around 1 a square foot. Or 7 inches of cellulose. So what are the advantages and disadvantages of each of these insulation materials.
