Introduction

Quiet Guard Stone Wool Insulation Batts are premium-grade mineral wool products engineered for the North American residential and light commercial market. Made from natural volcanic rock (basalt) and recycled slag, Quiet Guard batts deliver outstanding thermal resistance, acoustic attenuation, and Class A1 non-combustible fire performance — all in a friction-fit batt that installs without mechanical fasteners.

Quiet Guard AcousBatt™ — Interior Acoustic & Fire Series

Engineered for interior partition walls, floors, and ceilings where noise control is the primary goal. At 3″ or 6″ thick, the high-density stone wool fiber structure absorbs airborne sound and reduces impact noise transfer while providing a non-combustible thermal break.

Quiet Guard ThermaBatt™ — Exterior Thermal & Acoustic Series

Engineered for exterior walls, attics, exposed floors, basements, and crawl spaces where a rated R-value is required. Available from R14 through R32, fitting 2×4 through 2×8 stud cavities with higher density, better fire resistance, and added sound reduction vs. standard fiberglass batts.
