When insulating your attic you will need to choose from Batt or roll insulation, and loose fill insulation. So what are the differences between the two? We thought we would spell it out for you so you have a general knowledge of the differences. Contact us to talk about your situation.
Batt or Roll Insulation – The more common type of insulation that comes in the form of a roll that consists of flexible fibers, usually fiberglass. You also can find rolls made from minerals, wool, plastic and natural fibers, such as cotton or sheep’s wool.
Rolls are available in widths of standard spacing of wall studs, and attic or floor joists.They are available with or without facings. Manufacturers often attach a facing to act as a vapor or air barrier. Rolls with special flame-resistant facing are available where the insulation will be left exposed. A facing also helps with fastening during installation. However, it’s recommended that you use unfaced rolls if you’re reinsulating over existing insulation.
Loose Fill Insulation – Loose-fill insulation consists of small particles of fiber, foam, or other material. These particles form an insulation material that conforms to any size or type of space. The ability to conform makes loose-fill insulation well suited for retrofits and for situations where it’s difficult to install other types of insulation.
Most material used for loose-fill insulation include cellulose, fiberglass, and mineral wool. These materials are made using recycled materials. Cellulose is primarily made from recycled newsprint. Most fiberglass contains 20%–30% recycled glass. Mineral wool is usually produced from 75% post-industrial recycled content.
