Attic insulation: Typically attics are blown in with loose-fill fiberglass or cellulose if there is enough space for a crew to work within the attic itself. In tight spaced attics batt insulation is common because of the inaccessibility to blow. It is compression fitted between the rafters.
You’ll find that the attic typically has loose-fill or batt insulation installed. More than likely, loose-fill insulation is usually less expensive to install than batt insulation. If installed properly, loose-fill insulation will provide your attic with better coverage.
