Fiberglass insulation expands when you take it out of the packaging. For ease of transport, as well as storage, do not open the package of insulation until you are ready to use it. Fit the insulation around windows and doors to fill gaps between the frame and the opening. While the entire gap should be filled for best results, packing the filling tightly will result in loss of insulation value. Fill firmly but don't over do it.

When you install insulation around a wire, split the insulation where it crosses the wire to surround the wire with insulation. This will help to keep air spaces from forming behind the wires. Always install the vapor barrier toward the living space. If your batt type insulation has an aluminum facing then allow about an inch of space between the facing and the wall board. To do this just staple the insulation to the inside of the stud rather than attaching it to the edge of it.

Leave insulation in its natural state. Don’t try to compress it and don’t try to fluff it up. This will interfere with the R values of the insulation and result in poor performance. Foam board insulation is great for basement applications because it does not absorb water or moisture. A vapor barrier should always be installed on basement walls first with the framing added later. This will lessen the amount of moisture that comes through the foundation walls.

Blown in insulation
Blown in insulation is loose fill-insulation, often made with cellulose. It is one of the easiest types of insulation to install for a do-it-yourself type person. When done properly the cellulose molds around pipes and fits into unusually shaped spaces often found in old homes.

In order to add blown in insulation to your home you will need to rent an insulation blowing machine. Once you do that, it is only a matter of blowing the insulation into the space.

Fiberglass Batt insulation
One of the least expensive ways to insulate walls is to fill the stud spaces with fiberglass batt insulation. It does not take any special skills, other than a lot of patience. When you are remodeling fiberglass batt is one of the simplest ways to upgrade your wall insulation. Do a thorough job, though; gaps can reduce overall efficiency by as much as 25 percent.

Blanket and roll insulation is useful for insulating long runs in homes. Any area that needs insulation that is longer than eight feet is a good candidate for this type of insulation.

Insulation keeps your home quiet and energy efficient. By upgrading or installing insulation yourself you can obtain these benefits for far less money than if you hired someone to do it for you, and you can make sure that the insulation is properly installed to give you the most benefit.
