Batt insulation comes in pre-cut panels and is used to insulate floors, walls, and ceilings. This type of insulation is generally made of fiberglass or rock and slag wool, although there are also natural cotton varieties available for thermal and acoustic installation. Fiberglass batt insulation is one of the most popular forms, as it tends to be fairly inexpensive and easy to install. If installed properly, this insulation can be effective, energy efficient, and long lasting.
For this insulation to be entirely effective, it is important for a homeowner to choose a suitable variety for the job. Pre-cut rolls may not fit a non-standard job area, so it may be necessary to purchase several extra and cut down the size of the insulation to fit the area. Flame resistant panels may be necessary in areas such as attics or basements where insulation may remain exposed.
If panels of insulation are cut to a customized fitting, it is important for homeowners to make sure the panels all still fit tightly together with no gaps after trimming. Gaps may cause issues with effectively heating and cooling the home.
When installing insulation inside exterior walls, it is important for homeowners to find panels that are thick enough to cover any gaps between the insulation and the drywall. If batt insulation is being installed in humid climates, it is generally best to use unfaced insulation, which comes without a vapor barrier and is conducive to reducing moisture retention problems. Mold and decay may also become a problem if faced insulation is used in warm and humid climates.
To maximize the effects of insulation, it may be necessary to provide additional sealants during installation. This is especially true of older homes that may have more cracks or gaps in the structure or design. Caulk and foil-faced hardboard are generally effective methods of covering any areas that could let in outside air drafts.
Batt insulation is generally considered to be straightforward and easy to install, but there are instances where it may require professional help. If the job is too large or covers areas that are hard to get to, it may be best for the homeowner to contact a service worker to assist in the trickier areas. Properly installed insulation can save money in energy costs over time, so hiring an insulation professional may be an investment for long-term savings.
