What is a Batt insulation
When people think of insulation what commonly comes to mind is batt insulation. Batt insulation is made of fiberglass or mineral wool (also called rock wool). Batt insulation was traditionally manufactured in rolls but is now manufactured and precut into industry standard sizes.
Installation of Batt insulation
Batt insulation is installed with facing (called kraft-faced batts) or without facing. The climate determines which type to use. In some climates the facing on batts can serve as a vapor barrier. Other climates require a separate vapor barrier, in which case unfaced batt insulation is installed. Batt insulation is manufactured in many different R-values. The R-value required for your project depends on your climate, local building codes and the area you are insulating.
The effectiveness of Batt insulation
Batt insulation can be used in nearly any type of insulation application. Batt insulation can be used to insulate floors, walls, ceilings and attics. While it can be used anywhere, oftentimes other insulation types such as blown-in insulation or spray foam insulation may be better options.
The effectiveness of batt insulation depends greatly on how it is installed. To achieve full R-value batt insulation cannot be compressed or packed into a space. A professional insulation contractor has the experience and skill to properly install insulation to maximize effectiveness.
