Our Fiberglass Wool Blanket is a high-performance thermal and acoustic insulation solution engineered for commercial, industrial and residential building projects worldwide. As a professional Chinese manufacturer, we craft Fire Resistant Fiberglass Wool Roll products that meet international building standards, delivering exceptional energy efficiency and safety for your construction and HVAC projects. All our Glass Wool Rolls are customizable in size, density and facing options, with full CE and ISO certifications to ensure compliance with European and global industry norms. Whether you need bulk orders for large-scale roofing projects or tailored solutions for industrial duct insulation, our Roofing Insulation Materials offer a cost-effective and durable answer to your insulation needs—submit an inquiry today for a free quote and OEM service.
Our Glass Wool Rolls stand out in the B2B insulation market by addressing the core pain points of construction and engineering projects: high energy consumption, fire hazards, excessive noise and complex installation. Each advantage is designed to boost project efficiency and reduce long-term operational costs:
Euroclass A1 Fire Resistance: Our Fire Resistant Fiberglass Wool Roll releases no toxic gas at high temperatures, minimizing fire risk for industrial workshops, commercial buildings and roofing systems—critical for meeting global fire safety codes.
Superior Thermal & Acoustic Performance: With a thermal conductivity of 0.036-0.038 W/(m·K) and R4.0 insulation value, our Glass Wool Rolls cut energy loss by 30%+ and dampen airborne and structural noise, ideal for noise-sensitive spaces like office buildings and HVAC systems.
Lightweight & Easy to Install: The flexible, lightweight design of our Fiberglass Wool Blanket speeds up on-site installation, reducing labor costs for your construction team—no special tools required for cutting and fitting.
Water & Moisture Resistance: Treated with a hydrophobic coating, our Roofing Insulation Materials resist moisture absorption, preventing mold growth and maintaining insulation performance in humid and outdoor environments.

As a core Roofing Insulation Materials option, our Fiberglass Wool Blanket is widely used for flat and sloped roofing, as well as exterior wall insulation of commercial malls, residential communities and industrial factories. It forms a tight thermal barrier to reduce air conditioning and heating costs, with weather resistance to withstand outdoor exposure.
Our Fire Resistant Fiberglass Wool Roll is the ideal choice for HVAC ducts, ventilation pipelines and industrial equipment insulation. It minimizes heat gain/loss during air distribution, improving HVAC system efficiency while reducing operational noise for commercial and industrial spaces.
For prefabricated and modular building projects. Our lightweight Glass Wool Rolls fit perfectly with prefab construction’s fast installation requirements, providing consistent thermal and acoustic insulation without adding excessive weight to the building structure.
We prioritize B2B clients’ unique needs with full Custom Glass Wool Rolls for Building Projects services: customize size, density, facing materials, packaging with your brand logo, and even adjust insulation performance for special project requirements. Our customization process is streamlined—demand submission → free design → sample production → bulk manufacturing—to save your project time.
All our Glass Wool Rolls are certified with CE, ISO 9001 (quality management), ISO 14001 (environmental management) and Euroclass A1 (fire rating), meeting LEED green building standards. Each batch of Fiberglass Wool Blanket undergoes strict factory testing to ensure consistent quality for your bulk orders.
We provide comprehensive after-sales service to support your project from procurement to installation: flexible MOQ for small and large orders, bulk order discounts for long-term partners, online technical guidance and onsite installation support for large-scale projects, 1-year official warranty and long-term follow-up maintenance. We also offer international shipping solutions, with professional logistics support to deliver Roofing Insulation Materials to your global project sites on time.
As a reliable manufacturer of Glass Wool Rolls and Roofing Insulation Materials, we are committed to delivering high-quality, cost-effective Fiberglass Wool Blanket solutions for global B2B construction, industrial and HVAC projects. Inquire now to share your project requirements, and we will provide a tailored insulation plan and competitive quote for you!
