When it comes to insulating your home, there are two commonly used materials to do the job, fiberglass and cellulose. Both materials improve the energy efficiency of your home but do so in different ways.
R-values refer to how well an insulation performs at blocking thermal transfer. The higher the R-value, the better the insulation performs.
Fiberglass and cellulose have similar R-values, with ranges depending on how and where they are installed.
Because fiberglass comes in batts or blown-in insulation and both materials can be loosely or densely installed, this can change the ultimate R-value you receive.
Fiberglass insulation comes in two forms, batts and blown-in. Fiberglass blown-in involves using a machine to pump the loose insulation into the wall cavities.
Cellulose insulation is always blown-in.
Cellulose is treated to help prevent rot, decay, and mildew but may still develop these issues if there is prolonged contact with moisture.
Fiberglass does not rot, decay, or promote mildew growth, but it may lose some of its R-value over time if it becomes compressed. Excessive moisture may cause it to compress and lose some of its air pockets, which in turn makes it less effective over time.
