The natural brown color reflects an eco-friendly manufacturing process with reduced formaldehyde emissions and improved indoor air quality.
ISOKING R19 unfaced brown fiberglass batt insulation is manufactured from premium molten glass fibers using advanced centrifugal processing technology. The product forms a soft, durable, and highly efficient insulation blanket with excellent thermal and acoustic performance.
ISOKING brown fiberglass batts use fructose-based binder technology and are formaldehyde-free, reducing the use of artificial dyes and helping improve indoor environmental quality. Compared with traditional insulation materials, brown fiberglass batts provide reliable thermal resistance while supporting green building standards and sustainable construction practices.
Our factory operates under ISO 9001:2000 quality management standards. We support OEM manufacturing, customized packaging, and private label services for distributors and construction material suppliers worldwide.
