For closed-cavity applications, blown-in-wall systems can wrap a home in a seamless, custom-designed, thermally efficient, sound-reducing blanket that leaves no space unsealed. It is uniform in application without settling, quick to clean up, and immediately ready for drywall. Sometimes called blown-in-blanket, blown-in-wall insulation provides much better coverage than traditional fiberglass batt insulation filling around boxes and securing small spaces. With its ability to form to small gaps and oddly sized obstructions, you’ll experience outstanding thermal performance and excellent sound control.
