Abstract
A loosefill insulation installation includes a loosefill insulation material made from fiberglass fibers. The loosefill insulation material unexpectedly has improved thermal performance, even though the amount of mineral oil applied to the fiberglass fibers is reduced. For example, the fiberglass fibers can be coated with a mineral oil in an amount that is between 0.1% and 0.6% of the weight of the fiberglass fibers, such as about 0.375%.
Claims9
A loosefill insulation installation comprising:
- a loosefill insulation material made from fiberglass fibers;
- wherein the loosefill insulation material has an average installed thickness of at least 10.5 inches;
- wherein the average thermal resistance (R) of the installed thickness of the loosefill insulation material is greater than or equal to 30;
- wherein the average density of the loosefill insulation material is less than or equal to 0.485 pounds per cubic foot;
- and
- wherein the fiberglass fibers are coated with a mineral oil in an amount that is between 0.1% and 0.6% of the weight of the fiberglass fibers.
