Quiet Quilt™ Indoor Soundproof Blanket

No. The 2 inch measurement describes the fiberglass thickness before assembly. It compresses when sewn behind the vinyl face and again when quilted to the MLV, which is standard practice for reaching the rated STC and NRC numbers. Cut the panel open and the fiberglass fluffs back to its full 2 inches.

The 2 inch blanket is standard and blocks more sound: STC 32 versus STC 27 for the 1 inch, with an R-8 thermal value versus R-4. Choose the 1 inch version only where space is tight and the higher rating isn't needed.

The 2 lb version uses a heavier mass loaded vinyl barrier: 2.2 lbs per square foot versus 1.4, raising the rating from STC 32 to STC 36 at 2 inches thick. Absorption stays the same at NRC 0.85. The 2 lb blanket is the choice for lower-frequency noise or a stricter blocking target.

The quilted vinyl facing gives off a light vinyl scent. An estimated 9 in 10 people don't notice it, and it fades over time. A smaller room makes any scent more noticeable, so residential customers sensitive to vinyl smell should request a sample before ordering.

Yes, on any Quiet Quilt blanket. Punch the new hole at least 1-1/2 inches from the edge, then set the grommet with a rubber mallet on a firm, hard surface, striking hard enough to fully pinch the material and brass together. For larger commercial jobs, a heavy-duty grommet kit with a punch and die set is available.

Not completely. Water can get into the small stitched holes where the quilted facing is sewn on, but the panels dry out with no lasting effects.
