Introducing Next-Gen Brown Glass Wool: Setting a New Standard for Acoustic and Environmental Performance

[Beijing , 2025.12.22]

– Leading insulation manufacturer Beijing Fanryn today unveiled its enhanced line of Brown Glass Wool Board Insulation, redefining expectations for soundproofing materials by seamlessly combining superior acoustic performance with a stronger commitment to sustainability and installer comfort.

Engineered for Superior Performance

The new generation retains all the acclaimed features that made it an industry favorite—exceptional Sound Transmission Class (STC) ratings, a Class A fire rating, and moisture resistance—while introducing key advancements. The refined fiber technology offers a 10% improvement in sound absorption coefficients in critical mid-frequency ranges, making it even more effective at blocking speech and office noise.

Focus on Health & Sustainability

Recognizing the growing demand for healthier buildings, the product now features an enhanced, bio-based binder that further reduces VOCs (Volatile Organic Compounds), supporting optimal indoor air quality for projects targeting WELL or LEED certification. Furthermore, the core material now incorporates a minimum of 60% recycled content, primarily from post-consumer glass, supporting circular economy goals without compromising an iota of performance.

Designed with the Installer in Mind

"[Your Company Name] listens to its users,", Head of Product Development. "Based on extensive contractor feedback, we've improved the board's handling. The new facing has a cleaner cut and generates less dust, while the material is more resistant to tearing during fitting. This means faster, more comfortable installations and less waste on the job site."
