Insulating an Attic

Why install insulation in an attic?  A significant amount of heat is lost through the roof, which makes the attic an important area to insulate. Attic insulation works like a cap – it traps the heat inside, increasing comfort and efficiency and serving as the first line of defense when protecting against outdoor weather and temperatures.

Before beginning an attic installation job, it’s important to check your current insulation. When checking insulation in a previously insulated space, use a yardstick to check the depth. The average home needs up to 19 inches of fiberglass insulation in the attic for maximum energy efficiency.

If the space requires additional insulation, an easy fix is to place insulation batts or rolls in the attic’s floor joists, on top of any existing insulation. For specific instructions on how to install batts and rolls in the attic, check out this video.

If the attic is unfinished or doesn’t have existing insulation, installing blow-in insulation, like Attic Protector®, offers installation efficiencies in that it’s typically easier and less time-consuming than laying batts or rolls. Blow-in insulation can also be added on top of existing insulation to get the R-value you desire. Rent this equipment from a nearby retailer that that you buy your insulation from.
