Installing Interior Wall Insulation
Properly installed insulation will provide your home with the most efficient use of energy and will help to control noise levels as well. It is also one of the easiest, although not the funnest, home repair/remodeling jobs you can do yourself.
Before working with insulation, make sure your skin is well covered. If any insulation gets in contact with your skin it will get irritated and itch. Also, many old houses contain harmful levels of asbestos which has been linked to mesothelioma. To protect yourself as best as possible, wear pants, long sleeve shirt and/or jacket, a hat, gloves, eye protection and a dust mask.
- To begin installation, first unwrap the insulation and unroll it. Make sure that by now you are wearing a dust mask because once you open the roll the little fiberglass particles will get everywhere and you do not want to breathe these in - trust me I know!
- Beginning at the top of the opening between the studs, simply press the insulation in place with the vapor barrier side facing you. This is the side with the paper and writing on it. Continue stuffing in the insulation until you reach the bottom of the opening.
- Once you have reached the bottom, using a sharp utility knife, cut off the insulation just a few inches longer than the opening. It is best to use compression on the insulation by pressing down on it while cutting to give you the cleanest cut. Cutting the insulation against a hard surface will help this as well.
- Stuff the bottom of the insulation into the opening. At this point, the insulation should hold itself in pretty well if it is a good tight fit.
- Most brands of insulation should have some flaps on both sides of the paper that you can unfold to use to staple it in place. To do this, after you have unfolded the flaps, use a staple gun to staple it to the inside of the studs. Stapling every foot or so should be good.
Insulating Small Openings
While the width the insulation comes in fits most standard sized openings, you may find you have a lot of smaller sized openings you will need to insulate as well. For this, you will need to cut the insulation using the same method described earlier, but instead going down the length of the roll. A good method for helping you get the right width for the space is to press one side of the insulation into the small opening and cutting down while pressing against the adjacent stud.
