What Is Insulation?

Insulation is the loose celled material used in various parts of a structure to help slow the transfer of heat into or out of your home.  

It is rated by it's Resistance value or R-value.  The higher the R-value, the more effective the insulation is at stopping the transfer of heat.  The amount of insulation should be determined by it's R-value, not by any amount of inches.

According to Xcel Energy, as much as 70 percent of the energy you pay for is used to heat and cool your home. A properly insulated and air sealed home results in lower heating and cooling bills, can increase the value of your home in a selling market and provide overall comfort by eliminating drafts and deadening loud noises in and outside of the home. 

Let's talk types of insulation...

Batted Insulation

Batt Insulation: 
  ♦ insulation strips made of flexible fiber glass. Most strips are 4 to 8 feet in length and made to fit between joists, beams and studs. Main uses are in the attic, floor, walls and cathedral ceilings.

Blown Fiber Glass Insulation

Loose Fill Insulation:
  ♦ is made with small particles of materials like fiber glass or cellulose. The material is loosely packed in a bag and then blown into cavities with a machine. Main uses are in attics, floors, walls and various hard to reach closed spaces.

Rigid Insulation

Rigid Insulation:
    ♦  is a rigid board made from fibrous material or plastic foams that are cut 24"-28" wide and vary in thickness.  Mainly used under the foundation slab and/or the exterior and interior foundation walls.

Closed - Cell Foam Insulation

Closed-Cell Foam Insulation:
   ♦  Closed-cell  foam has many tiny foam cells closed and packed together. These cells are filled with a gas that helps the foam rise and expand and become a greater insulator.  Mainly used in boxsills, crawlspaces and air sealing.
