Cellulose Versus Fiberglass Attic Insulation

Or 7 inches of cellulose.

Cellulose versus fiberglass attic insulation.

Cellulose insulation blown in attic r 3 6 r3 7. Cellulose insulation blown in wall r 3 8 r3 9. Fiberglass insulation is the easiest insulation product on the market to install and if installed correctly the most effective product on the market for home attic insulation. The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass.

If paired with a vapor barrier in a high moisture environment like your basement it can be problematic. Fiberglass batts however are less expensive costing on average 0 30 to 0 40 a square foot for 6 inches of insulation. So what are the advantages and disadvantages of each of these. You can get to the same place with either material.

When using cellulose blown in dry insulation it requires a machine to achieve its purpose and a training session from wherever you rent the blower from. Cellulose and fiberglass are fibrous insulation which can easily trap moisture. Both fiberglass and cellulose insulation can be installed to completely fill the space inside of wall floor or ceiling cavity. So it seems to me the real debate.

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. Lastly when blown onto the floor of an attic with vented soffits both loose fill cellulose and fiberglass are susceptible to wind.
