Should I use cellulose or fiberglass insulation?

Cellulose insulation is safe. In fact, many professionals consider cellulose to be more fire-safe than fiberglass. This claim rests on the fact that cellulose fibers are more tightly packed, effectively choking wall cavities of combustion air, preventing the spread of fire through framing cavities.

What type of home insulation is best?

foam insulation
Overall, if you are looking for the best long-term solution, foam insulation products will create the air seal in your home that will make it more comfortable while saving you money on your monthly energy bills. Foam insulation doesn’t settle or sag and it fills all the nooks and crannies where it is installed.

Which is better foam insulation or fiberglass insulation?

Fiberglass insulation packs in more R-value per cubic inch than rigid foam insulation does. If conserving energy is your main goal and there are no other influencing factors such as moisture, fiberglass insulation should be your first choice.

How long does cellulose insulation last?

20 to 30 years
Because it is made primarily of recycled materials, however, cellulose insulation does degrade over time. The typical lifespan is 20 to 30 years, with degradation beginning as early as 15 years after installation. As with other types of insulation, severe weather or outside interference can reduce the lifespan.

How much does cellulose insulation cost?

Blown-in cellulose is often more expensive than fiberglass and costs about $1.20 per square foot. The cellulose insulation cost per bag is typically around $30 to $40….Cellulose Insulation Cost.

Material	Cost per Square Foot	Project Sustainability
Wet-Spray Cellulose	$0.60 – $1.80	New construction

Is cellulose insulation safe?

Cellulose insulation is safe. It is made of paper, but the chemical treatment provides it with permanent fire resistance. In fact, many professionals consider cellulose to be more fire-safe than fiberglass.

What is cheaper foam insulation or fiberglass?

On the whole, spray foam insulation costs two to three times as much as fiberglass insulation. Fiberglass insulation costs around $0.40 per square foot. Spray foam can be significantly more expensive, but can lead to bigger savings on heating and cooling costs.

What type of insulation is the most energy efficient?

Spray foam insulation
Spray foam insulation is the most energy-efficient insulation to create an air barrier in the attic. Certain spray foams can expand up to 100 times its original size, so it fills all of the nooks and crannies in the attic.

Does cellulose need a vapor barrier?

With Modern’s Cellulose insulation, a vapor barrier is not recommended except in very cold weather or high moisture areas such as spas or pool buildings. However, many building codes do require an Air barrier or Vapor retarder to be installed. Cellulose insulation has a high density compared to fiberglass.
