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. There are also natural cotton varieties available for thermal and acoustic installation. Fiberglass batt insulation is one of the most popular forms of insulation, as it tends to be fairly inexpensive and easy to install. If installed properly, batt insulation can be effective, energy efficient and long lasting.
For batt insulation to be entirely effective, it is important 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 feet 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 to make sure the panels all still fit tightly together with no gaps after trimming. Gaps in insulation may cause issues with effectively heating and cooling the home.
