The amount of insulation in your home has a good deal to do with how often and long your furnace runs. Its sole purpose is to slow down heat transfer from the inside out in the winter or the outside in during the summer. Adding more of the best type could be the most cost effective way to cut energy bills.
Fiberglass batts are the most common kind of insulating materials used in new homes since they’re effective and easy to install. You’ll find them in the attics, walls and the ceilings of basements. Recycled denim and mineral wool batts are also available, although less commonly used.
Batts can be used to:
- Increase the amount in attics.
- Add to basement ceilings.
- Replace existing wall insulating materials when removing siding or drywall.
Loose insulating products made from cellulose and fiberglass are used in attics and sometimes walls in new construction. Cellulose is shredded, recycled newspapers treated with chemicals to resist fire, moisture and insects.
Blown-In applications include:
- Improving the insulating values in attics.
- Filling large gaps in walls.
Rigid Foam Boards
These sheets fit between floor joists or wall studs. It provides more insulating value than either blown-in or batt insulation. Foam boards resist water, mold and insects.
Use foam board when you’re:
- Insulating the basement walls, attic hatches and garage doors.
- Increasing the amount in the attic or between wall studs.
Sprayed-on Insulating Foams
These products are almost always applied by a professional because they require specialized equipment. Insulating foams offer the best protection against heat transfer and are also the most expensive to install. They’re durable and also eliminate the need for air sealing, since they swell to conform to the cavity once applied.
Opt for sprayed-on foam when:
- Insulating a roof deck;
- Insulating and sealing tight spaces in attics or walls.
