Cellulose

Anderson Insulation is New England’s expert when it comes to cellulose installation.

Cellulose Blown-In insulation is one of the most commonly used and seen insulation in homes across New England. This insulation is made up of wood fiber and newspaper waste, and is very fire resistant. This is because the insulation is coated in borate which gives the insulation its fire resistant trait.

Anderson Insulation uses cellulose Nu-Wool® insulation to insulate homes that previously had no insulation to save homeowners and companies money for heating and cooling costs. Decades later, we stillfind homes with little to no insulation. Cellulose is a key way to insulate a home without having to do extensive renovations. It can be blown in from either the inside or outside. Today, many new construction homes are using cellulose insulation it their attics to meet the current building code standards.

Why Cellulose?

  • Lightweight – Cellulose has a density of 1.6 pounds per cubic foot area. This allows the insulation to be layered on for multiple protection along without fear of being too heavy.
  • Long, Flexible Fibers – Since the individual fibers of the cellulose insulation are long and flexible, they can be blown into any part of the house. No matter if it is the basement or attic, this insulation can be placed in the smallest of places even as small as 5/8 of an inch.
  • High R-Value – R-value measures the thermal resistance of insulation and how quickly the insulation will lose heat. The higher the value, the better the insulation. Cellulose has a higher R-Value than most insulation, 3.7. This means there is a less chance a house would lose heat during the winter.
  • Non-Corrosive – Since this type of insulation is non-corrosive, it will not affect other building material of the house overtime.
  • Moisture – Cellulose has millions of microscopic air cells that help evaporate moisture before it can collect and damage plaster, paint, framing members, etc.
  • Settlement – This type of insulation is great for houses as it won’t settle inside the walls.

If you are environmentally conscious, then you do not have to worry with cellulose insulation. The insulation is made up of 85% recycled products, as well as being treated with fire retardant chemicals to keep you safe. It is becoming a favorite among the LEED (Leadership in Energy & Environment Design) certified builders.

When it comes to new construction, cellulose can be damp-sprayed applied. NuWool cellulose insulation is mixed with water and a glue like substance, that allows the cellulose to adhere to plywood sheathing, roofing and walls much like foam. This is done when semi-transparent mesh netting is stretched tightly across the surface of the wall, slope and stapled in place. Holes are then made in the netting and the cellulose is blown into the bay.
