What Is Glass Wool Board and How It Works

Definition and core performance of glass wool board for insulation

Glass wool board for insulation is a rigid or semi-rigid panel made from spun glass fibers bound into a stable board. It provides thermal insulation by trapping air in microscopic pockets, lowering heat transfer. Typical thermal conductivity ranges from approximately 0.033 to 0.045 W/m·K depending on density and temperature—making it highly effective for energy-saving applications.

Key Specifications You Should Know

Density, thickness and standard board sizes for glass wool board for insulation

Wholesale buyers should consider density (often between 24–160 kg/m³ for various board types), thickness (commonly 25, 50, 75, 100, 150 mm), and sizes (standard sheets like 1200×600 mm and 2400×1200 mm). Higher density boards offer better compressive strength and lower thermal transmittance but may cost more by weight and volume.

Thermal and Fire Performance

Thermal insulation and fire safety of glass wool board for insulation

Glass wool board for insulation typically delivers low thermal conductivity and high thermal stability. Glass fibers have softening/melting points well above 600°C, which contributes to excellent fire performance—many glass wool products are classified as non-combustible under common standards. FUNAS products carry multiple international certifications (CE/ROHS/CPR/UL/FM) and national CCC/CQC approvals, reinforcing compliance for demanding projects.

Acoustic and Mechanical Benefits

Sound absorption and mechanical properties for building applications

Glass wool board for insulation also provides sound absorption (NRC values typically between 0.6–1.0 depending on thickness and facing). Mechanical strength varies by density; board products designed for ductwork, chiller enclosures, or partition panels can include facing (foil, glass tissue) for added durability and vapor control.

Sustainability and Environmental Considerations

Recycled content and lifecycle advantages of glass wool board for insulation

Glass wool boards often contain a significant proportion of recycled glass (commonly 40–70% depending on the formula), reducing raw-material demand and embodied energy. FUNAS has ISO 14001 environmental system certification, underlining its commitment to sustainable manufacturing. Glass wool insulation helps reduce operational energy use in buildings and industrial plants, contributing to lifecycle carbon reductions.

Common Industrial and Commercial Applications

Where to use glass wool board for insulation—industries and systems

Wholesale glass wool board for insulation is widely used in petroleum and petrochemical plants, power generation, metallurgy, polysilicon manufacturing, coal chemical facilities, central air-conditioning systems, refrigeration systems and commercial buildings. Its flame resistance and thermal performance make it suitable for pipe insulation, equipment lagging, cold-room panels, HVAC ducts, and plant insulation.

Types and Variants: Faced, Unfaced, and Coated Boards

Select the right facing and coating for your project needs

Glass wool board for insulation comes faced (foil, kraft, glass-fiber tissue) or unfaced. Facings add vapor control, mechanical protection, and aesthetic finish. For outdoor or high-humidity environments, aluminum foil facing or vapor barrier coatings are recommended. FUNAS offers brand customization and a range of facings to match project specifications.

Quality, Certification and Compliance

Certifications that matter when buying wholesale glass wool board for insulation

For bulk procurement, certifications are critical. FUNAS has achieved CCC and CQC compulsory product certifications in China and international CE, ROHS, CPR, UL and FM approvals. The company also passed ISO 9001 and ISO 14001 systems, demonstrating quality management and environmental control—key for international tenders and code-compliant projects.

How to Choose a Wholesale Supplier: Key Commercial Considerations

Factors buyers evaluate when sourcing glass wool board for insulation in bulk

Evaluate manufacturer capacity, lead times, MOQ (minimum order quantity), price per square meter or kilogram, customization capability (branding, packaging, faced/unfaced options), technical support, and logistics. FUNAS maintains a large Guangzhou warehouse for faster fulfillment and offers brand customization services to meet customer-specific requirements.

Pricing Drivers and Cost-Saving Strategies

What influences the price of glass wool board for insulation and how to optimize cost

Key price drivers include density, thickness, facing, recycled content, transport distance, and order volume. Wholesale buyers can reduce unit costs by ordering larger volumes, standardizing board sizes and thicknesses across projects, and choosing common facings. FUNAS supports bulk pricing and tailored logistics to help reduce total landed cost.

Packaging, Shipping and Logistics for Wholesale Orders

Efficient packaging and shipping practices for bulk glass wool board for insulation

Boards are typically compressed and shrink-wrapped onto pallets for sea or land transport. FUNAS’s 10,000 m² Guangzhou storage center allows consolidated shipments, LCL or FCL arrangements, and optimized export documentation. For international buyers, proximity to major ports in Guangdong reduces transit time and freight expense.

Installation Best Practices

Practical tips to ensure performance of glass wool board for insulation

Store boards dry and flat before installation. Use appropriate protective gear (gloves, masks) to avoid fiber irritation. Seal joints and edges with compatible tapes or mastics; in cold applications, add a vapor barrier to prevent condensation. Proper fastening and support minimizes thermal bridging and maintains rated R-values.

Customization and OEM Services

Brand customization and product tailoring for bulk buyers of glass wool board for insulation

FUNAS offers brand customization services including private labeling, tailored facings, specified densities and thicknesses, and custom packaging. This is valuable for distributors, systems integrators and OEMs who require product consistency under their own brand for resale or integrated systems.

Case Studies: Typical Wholesale Use Scenarios

Examples of large-scale applications for glass wool board for insulation

Examples include insulation packages for central HVAC systems in commercial towers, refrigerated warehouse panels for cold-chain logistics, and equipment lagging in petrochemical plants. In each case, buyers prioritized boards with the right density, facing and fire compliance to meet project codes and performance targets.
