Insulation Products

Over the years, insulation materials have transformed. In the past, they included items such as rock wool, vermiculite, mineral-wool and many other kinds of materials. Currently there are two choices for blow in attic insulation, either cellulose or fiberglass. It is important to consider a number of factors when choosing an insulation product such as application efficiency, thermal performance, value and of course SAFETY! Select feels that the best, most cost effective way to protect your home investment from continually rising fuel & energy cost is with fiberglass blow in insulation.

Fiberglass material has been around since the turn of the 20th century, however the first fiberglass insulation product was not offered for sale until the late 1930's. Originally its only competitor was asbestos. However, during the 1960's and 1970's, the public began to understand the carcinogenic potentials that asbestos contained. Since fiberglass insulation offers many of the same insulation qualities without the carcinogenic threat, it quickly grew in popularity.

Fiberglass has a number of inherent qualities which make it a good insulating material. It is made from the same kind of glass as cookware and glassware found in the kitchen. However the fibers are created by filtering small amounts of hot glass through a tiny opening to create a very thin and small glass fiber. These fibers bundled tightly together are excellent at trapping heat. This allows an insulated building to retain a set temperature for a longer period of time as compared to a building that has no insulation. These same traits also prove to be effective in reducing sound transmission. This is especially helpful for homeowners located near a busy airport.

Choosing the Right Product

Fiberglass:

Advantages
    • Does Not Settle thereby maintaining its R-value with age.
  • Fiberglass insulation does not absorb moisture. If it becomes wet, it will dry out quickly.
  • VERY light in weight.
  • Naturally noncombustible and remains so for life!
  • Composed of sand & RECYCLED glass.
  • Clean, vibrant white or pink color.
  • Does not wear out or lose efficiency over time
  • Limits sound transmission
  • Thermal efficiency - which provides energy saving benefits
Disadvantages
  • Rigid glass fibers
  • Will irritate and itch the skin upon contact
  • Susceptible to wind

Cellulose:

Advantages
  • No itching
  • Made of recycled material
  • Limits thermal changes
  • Limits sound transmission
Disadvantages
  • Settling & loss of R-value - May settle as much as 20% which will cause it to lose some of its desired R-value.
  • Water Vapor Absorption - Made of shredded newspaper, it will absorb moisture thereby reducing its energy saving potential.
  • IMPACT of weight � it is a heavier substance, therefore the higher the R-value unfortunately the stronger potential for ceiling drywall to sag
  • Is naturally combustible; therefore it has to be HEAVILY treated with a fire retardant chemical. The question remains: How long this chemical treatment will last??
  • Dirty grey color.
  • Susceptible to wind
