Insulation helps in decreasing the amount of energy used. By doing this, it keeps or home comfortable all year-round. The higher the R-value, the better the material insulates. Both fiberglass and cellulose are used as per the access to the attic. When making a product choice for your insulation, always contact a professional

 

Fiberglass Insulation

It is a mineral fiber that is obtained from recycled sand, glass and other materials. It is available in three types, namely:

  • Batts – fiberglass batts are for placement between flames. It is used during the construction of walls, floors, ceilings, and attics. The batts are denser than blown-in insulation.
  • Rolls – Rolls are pre-cut to fit in between joists and studs. They are great to use on the floor and attics.
  • Blown-in – this is ideal for insulating wall cavities or attics. It ensures maximum coverage. It can also be applied over existing insulation.

 

Pros of Fiberglass Insulation

  • Easy installation for DIY
  • Non-flammable
  • Does not promote mold and mildew
  • Different styles of insulation available

 

Cons of Fiberglass Insulation

  • In extreme cold, it may lose the R-value
  • Not moisture resistant
  • Not an air barrier
  • May lose its R-value if compressed
  • Health concern to installers

 

Cellulose Insulation

This is an alternative for blown-in fiberglass. It is made up of 80-85% recycled paper. Cellulose installation is denser than blown-in fiberglass. It has a better R-value compared to cellulose.

 

Pros of Cellulose Insulation

  • Doesn’t lose its R-value in extreme cold
  • No health concerns
  • Can be dense or loose as needed
  • Does not degrade
  • Environment-friendly
  • Fills cavities well

 

Cons of cellulose Insulation

  • One insulation style
  • Not an air barrier
  • Not moisture resistant

 

Comparison between Cellulose and Fiberglass

  1. Cellulose has an R-value of 3.5-3.7 per inch while fiberglass has an R-value of 2.1-2.7 per inch.
  2. Cellulose is 38% better air infiltration than fiberglass.
  • Cellulose is more efficient at retaining its R-value across different temperatures than fiberglass.
  1. Cellulose insulation is the ideal type where there are cracks present in attics.
  2. Cellulose insulation forms a dense mat. By this, it helps in curbing noise coming from outside.

 

Both cellulose and fiberglass are great choices. However, in making your selections, consider the following:

  • Your target R-value
  • Environmental impact
  • Drawbacks of fiberglass compared to cellulose

If you are thinking of upgrading your attic insulation, you have to choose cellulose. It is a wise decision because of its chicken and egg benefits and properties. You won’t regret this!
