• What is the cost of attic insulation?

  Attic insulation is sold by the square foot, so the cost of attic insulation depends on the amount that is installed (inches) and the square footage of the area to be insulated.  Mills installs insulation at different levels ranging from 5″ up to 22″.  Mills will make Department of Energy recommendations based on the information we gather about your home.  You can adjust the amount of insulation to be installed to suit your needs, and you’ll be able to see the exact cost of attic insulation before the service is performed.

• What is R-Value?

  “R” stands for resistance to heat flow. The higher the R-value, the greater the insulating power. R-value is measured through a series of industry standard  tests.  Manufacturers of insulation products print the R-value of their products on either bags or on labels attached to plain bags. In most cases, R-value is also printed on the facings of batts and rolls. On unfaced insulation, R-value may be printed on the product or indicated by stripe coding. R-value is a representation of the amount of energy (or heat) that can pass through a material (the insulation) over a certain area (the size of your attic) in a certain amount of time.

• Does Fiberglass contain any recycled material?

  Yes. Today’s fiber glass insulation contains typically 20-40% recycled glass, depending upon the manufacturing facility and product type. source

  In the last decade, manufacturers of fiber glass and slag wool insulation have diverted more than 20 billion pounds of glass and blast furnace slag from America’s solid waste stream. Fiber glass insulation manufacturers recycle more material by weight than any other type of insulation used in the building and construction sector. In the last ten years for which data is available, nearly 9.5 billion pounds of recycled glass and nearly 11 billion pounds of recycled blast furnace slag have been used in the manufacture of fiber glass and slag wool insulation. Fiber glass uses a high percentage of recycled material which helps the environment by diverting materials from the solid waste stream. Fiber glass insulation manufacturers are the 2nd largest user of post-consumer recycled glass in the US.  source

• Fiberglass Insulation vs Cellulose Insulation?

  There are three important differences between fiber glass and cellulose:

  Fire Resistance

  Fiber glass is made mostly of inorganic materials and therefore is naturally non-combustible and has a low flame spread rating. It will maintain its fire resistance over its lifetime. On the other hand, cellulose is made up of newspaper, which is organic and naturally flammable. Therefore, approximately 20% of the finished cellulose product is comprised of fire retardant chemicals (80% newspaper / 20% fire retardant chemicals). These fire retardant chemicals may not be applied consistently and may deteriorate over time. Smoldering and re-kindling of fires have been reported with this product.

  Moisture Absorption

  Fiber glass is installed dry and does not absorb or retain moisture. Cellulose is often installed damp and needs to fully dry after installation. Even after drying, cellulose can absorb moisture, which can lower the R-value of the product and may promote fungal growth.

  Settling

  Fiber glass has nearly no settling (1-3%). Therefore, the R-value is stable over time. However, fiber glass must be installed correctly to achieve the desired R-value. Cellulose can settle or shrink causing the R-value to deteriorate over time. Unless 20% or more extra thickness is installed, you can’t be sure of achieving the desired R-value.
