Is it easy to transport given its large volume?

Very easy. We use vacuum-compressed packaging for shipping, which saves a huge amount of space and freight costs. Once unpacked at the construction site, the glass wool will quickly rebound to its original thickness without affecting its performance.

Key features

Superior Thermal Insulation: With ultra-low thermal conductivity, glass wool significantly reduces heat transfer, effectively cutting energy consumption for buildings and equipment.

Eliminate Noise Hassles: The porous sound-absorbing structure reduces noise pollution in equipment rooms, walls and pipelines without the need for extra soundproof materials.

Class A Fire Safety: As a non-combustible material with Class A1 fire performance, it releases no toxic smoke when exposed to fire, greatly enhancing building fire safety.

All-scenario Insulation: Lightweight, flexible and easy to cut, it can be quickly installed and adapted for industrial pipelines, HVAC systems, cold storage and external wall insulation.

Durable & Moisture-Resistant: Compared with traditional insulation materials, glass wool has stable chemical properties, resists moisture and mildew, extending its service life by over 30%.

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and ODM capabilities, reports new product development within the past year, and operates two production lines with stated inventory capability. It has written procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaints. Management-system certifications include ISO9001:2015, ISO45001:2018, and ISO14001. Reported delivery lead times are within 15 working days in both peak and off-season, with access to Guangzhou, Foshan, and Shenzhen ports. However, the supplier began exporting only one year ago, has no valid manufacturing-capacity contract with related subcontractors, and lacks overseas warehouse and showroom capabilities. No collaboration with Fortune 500 companies is reported. The available financial information is incomplete and inconsistent in detail, so financial credibility cannot be conclusively assessed.

Supplier typeThe supplier is presented as a manufacturer with a technical team, hundreds of production and sales personnel, two production lines, and in-stock capability. However, it reports no valid contract with related subcontractors, so the precise manufacturing structure and capacity governance are not fully established.

CertificationsThe supplier explicitly reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. Product compliance certification and raw-material quality reporting are listed only as “Others,” without specific certification names.

After-Sales capabilityWritten procedures and followed records are reported for service-capability assessment, corrective and preventive actions, and customer complaints. Service terms include multiple quotation and payment options, while stated peak- and off-season lead times are within 15 working days; overseas warehouse and showroom services are unavailable.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and a technical team developed through continuous improvement. These statements provide explicit evidence of product-development capability.

Production capacityThe supplier reports two production lines, inventory capability, and lead times within 15 working days in both peak and off-season, with access to three nearby ports. However, it has no valid contract governing manufacturing capacity with related subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full customization, minor customization, and flexible customization. It also provides ODM services, indicating broad support for customer-specific product development.

Client casesThe supplier explicitly reports no collaboration with Fortune 500 companies. No other named customer cases or verified customer references are provided in the slices.

Product Q&A

Q:What is the fire rating of your glass wool?

Our glass wool is an inorganic fiber with an A1 non-combustible rating. It does not support combustion or release toxic fumes when exposed to high heat or open flames, ensuring maximum safety.

Q:Is your glass wool eco-friendly and safe?

Absolutely. We use advanced manufacturing processes to ensure our products are formaldehyde-free and asbestos-free. While we recommend wearing masks and gloves during installation to prevent skin irritation, it is completely harmless to humans once installed and sealed.

Q:Is glass wool resistant to moisture?

Yes. Our high-quality glass wool has a water repellency rate of over 98%, meaning it resists water absorption well. Its performance remains stable even if it gets damp and dries out. For extremely humid environments, we recommend using it with a vapor barrier.

Q:How is the soundproofing performance?

It offers excellent sound insulation. The porous fiber structure effectively absorbs sound waves, making it especially great at absorbing medium to high-frequency noises (like human voices or equipment hum) and significantly reducing indoor reverberation.

Q:Do you support custom sizes and facings?

Yes, we do. We can customize any density, thickness, and dimensions to meet your needs. We also offer various facing options, including Aluminum Foil, PVC, Fiberglass Mesh, and Kraft Paper, to suit different application scenarios.
