Most homeowners looking for batt insulation in Pittsburgh know that it is made of fiberglass called mineral wool or rock wool. Batt insulation was traditionally manufactured in rolls, but these days it is manufactured and precut into industry-standard sizes. Batt insulation is installed either with facing (kraft-faced batts) or without facing.
The climate in which the home is located determines which type to use. In some climates, it’s helpful that the facing on batts can serve as the vapor barrier. A separate vapor barrier is required in other climates, and in these areas, unfaced batt insulation is installed. Batt insulation is manufactured in many different “R-values.” The R-value required for your building project will depend on your climate, local building codes, and the area of the building you are insulating.
Typically, batt insulation can be used in almost any type of insulation application. It can be used to insulate floors, ceilings, walls, and attics. Even though it can be used anywhere, sometimes other insulation types such as spray foam insulation or blown-in insulation may be better options.
The effectiveness of batt insulation depends significantly on how it is installed. To achieve full R-value, batt insulation should not be compressed or packed into a space. Professional insulation contractors have the experience and skills to install insulation properly to maximize effectiveness.
