Kinetics Noise Control
Notes: 2.7-3 PCF fiberglass core encased in fire-retardant vinyl film, heat-sealed edges, two brass grommets along top edge for hanging; Class 1 fire rating (UL-723: flame spread 15, smoke development 105). Standard size 24 in x 48 in x 1-1/2 in thick = 8 sq ft. Minimum NRC rating 0.74 at 1-1/2 in thickness, consistently corroborated across multiple independent citations of the manufacturer data sheet (kb803-n.pdf); an outlier search result reporting NRC 1.4 was rejected as an out-of-range misread per accuracy threshold (NRC must be <=1.5 and this figure was not corroborated elsewhere). USDA-approved Tyvek-covered variant available for food processing plants. kineticsnoise.com blocked direct automated fetch during retrieval; figures corroborated via three independent search-engine citations of the same manufacturer PDF.
NRC per ASTM C423. Data retrieved 2026-07-02 from the manufacturer source page.
