We use many types of insulation, but primarily fiberglass. When installed properly fiberglass is the most cost-effective option and doesn’t have any of the problems (noxious chemicals, settling, etc) associated with spray foam, cellulose, or rock-wool. The fiberglass we use is not like the fiberglass of 10 years ago; it does not contain formaldehyde and therefore doesn’t itch or have any odor.
What kind of insulation do you use?
