Batt Insulation

Insulation can be bought in four basic and different types: rigid board, batt or blankets, spray, and ridge. Batt insulation is one of the more inexpensive types of insulation but it is also one of the more difficult to install. Batt insulation is made out of mineral fiber. This mineral fiber can be made out of rock wool or processed fiberglass. Fiberglass Batt insulation is the more popular of the two. One can get the best insulation from Batt which are perhaps the most cost-efficient insulation option these days.


Batt insulation like garage door insulation is used to insulate ceilings, floors, and walls. The best type of building type to use with Batt insulation is the standard joist, stud spacing, or rafter with a spacing of around sixteen to twenty five inches. Batt insulation usually comes in fitted widths that will tightly fit in between the wood framing for your necessary job. You can also find Batt insulation such as exterior wall insulation that includes a radiant barrier backing. The fitted pieces are sold in lengths of four to eight feet normally and blanket types come in long rolls that need to be cut for the custom fit. Batt insulation can be purchased with or without facings. Facings are used for attics or exterior walling. The material that makes up the facing is used as a vapor reducer and helps makes installation easier.

You will need to use Batts of R-30 or R-38 when installing insulation. The exterior types will use R-13 to R-21. Interior types are usually suited for soundproofing and control and the R-11 is the most common. After opening the packages by cutting them long ways through the panel on the side you will avoid cutting the batting or the facing that is on it. The product will expand fast and completely in a short amount of time. Push the Batt insulation into the crevices and be sure to pay close attention to the edge and the sides.

You will need to enhance the full expansion of Batt insulation by pulling the insulation to the front and letting it expand after opening the bag. Facing Batts will need to be sure to make the vapor retardant is facing the interior space that was previously conditioned unless the building codes state otherwise. Be sure to be certain that the insulation is secured with fastener “lightning rods” and they are pressed against the subfloor area without squeezing it. When installing Batt insulation you need to cut short spaces to fit it in the correct manner. You can customize Batt insulation to fit correctly. Don’t leave spaces in between in any spot. It will probably take more than one Batt insulation area to fill the complete area in the wall. You will need to make sure the Batt insulation fits securely and properly before finishing the job.
