professional should specify insulation thickness based R-value on the “6.0 R/inch” design guideline associated with the old LTTR test method. Likewise, for jobs that will be permitted in 2014, the design professional should specify insulation thickness based on the “5.7 R/inch” design guideline associated with the new LTTR test method.

How well insulation works is expressed by its R-value, which measures resistance to the flow of heat. The higher the R-value, the better it insulates per inch of thickness. The amount of insulation recommended for your home is dependent on where you live, but here are some general guidelines: Attic ...

Types of Insulation Insulation comes in many different


When insulating your home, you can choose from many types of insulation. To choose the best type of insulation, you should first determine the following: Where you want or need to install/add insulation; The recommended R-values for areas you want to insulate.


R-value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another. As a benchmark, one inch of solid wood has an R-value of 1. In comparison, an inch of blown fiberglass insulation has an R-value of 3.1 - 3.4 and an inch of blown cellulose in an attic has an R-value of 3.2 - 3.7
