How To Insulate Your Home
Perhaps the most important area of a home to properly insulate is the attic floor. Since warm air rises, the attic is where most of the home's heat is lost (resulting in higher utility bills). But what type of insulation should be used to keep warm and cool air from escaping? There are lots of choices. The types of insulation most likely to be sold in Do it Best stores are loose fill, blanket, batt, or reflective foil. Each of these can be used for a variety of insulation purposes, including attic floors. The main difference is in their installation.

Fiberglass blanket insulation is the most commonly used for do-it-yourself projects because of its easy roll on installation. Batt insulation also rolls on like blanket insulation, but batt insulation is pre-cut or perforated into shorter lengths. Loose fill insulation is installed by pouring it into place and then spreading it evenly with a board or rake. Loose fill insulation is most often used in walls and between joists on the attic floor. Reflective foil insulation comes in long rolls of various widths. It's installed easily with glue, reflective tape or a staple gun.

Now, no matter which insulation material is used, the important part to remember is that any insulation's effectiveness is measured in R-values. "R" stands for resistance. The higher the R-value, the greater the insulation's effectiveness.

An important thing to remember about R-values is that they can be added together. For example, if two R-19 fiberglass blankets are stacked on each other, they will provide R-38 insulation. So, how do you know when you need more insulation? One rule of thumb is that if the attic floor has less than 6 inches of insulation, it's a good idea to add more.
