Wholesale mineral wool blanket manufacturer and supplier

Introduction: Why Choose a Wholesale Mineral Wool Blanket Manufacturer and Supplier

Choosing the right wholesale mineral wool blanket manufacturer and supplier is critical for projects that demand reliable thermal performance, fire safety, and acoustic control. A mineral wool blanket is a high-performance insulation product commonly used across petroleum, petrochemical, power generation, metallurgy, polysilicon production, central air conditioning, refrigeration and other heavy industries. As an established supplier, FUNAS offers production scale, certifications and customization to meet industrial and commercial needs.

What Is a Mineral Wool Blanket and How It Works

A mineral wool blanket, often called rock wool or glass wool blanket depending on raw material, is made from spun mineral fibers bonded into a flexible mat. Mineral wool traps air in its fibrous structure, reducing heat transfer by conduction and convection. This structure also provides excellent acoustic dampening and non-combustible performance. The term mineral wool blanket covers a range of densities and thicknesses designed for pipe, duct, wall and equipment insulation.

Types of Mineral Wool Blanket Offered by Wholesale Suppliers

Rock Wool Blanket

Rock wool blanket, made from basalt or other natural rock, is typically non-combustible and suited to high-temperature applications. It is widely used in petrochemical, power and metallurgy where fire performance and high-temperature stability are essential.

Glass Wool Blanket

Glass wool blanket, produced from recycled glass and soda ash, offers lower thermal conductivity at moderate temperatures and is often used for HVAC, refrigeration and building insulation where flexibility and cost-effectiveness are priorities.

Specialty Mineral Wool Blankets

Wholesale suppliers also provide specialty options such as high-density blankets for equipment insulation, faced blankets with vapor barriers or foil facings for weather resistance, and acoustic-specific blankets with enhanced sound absorption.

Key Technical Specifications Buyers Should Evaluate

Thermal Conductivity

Thermal conductivity (lambda value) indicates heat transfer. Typical mineral wool blankets have thermal conductivity in the range of approximately 0.032 to 0.045 W/mK, depending on density and temperature. Lower values mean better insulation.

Density and Thickness

Density usually ranges from about 40 to 200 kg/m3 for mineral wool blankets. Lower densities are used in building insulation and HVAC, while higher densities suit industrial pipe and equipment insulation. Thickness selection depends on the required R-value and space constraints.

Temperature Rating and Fire Performance

Rock wool can withstand significantly higher service temperatures than glass wool. Typical rock wool blankets are rated for continuous use up to several hundred degrees Celsius; some specialty stone wool products maintain integrity at even higher temperatures. Importantly, rock wool is classified as non-combustible (often A1 per EN 13501-1), making it ideal for fire protection applications.

Sound Absorption

Mineral wool blankets are effective at absorbing airborne sound; NRC (Noise Reduction Coefficient) values depend on thickness and density. They are commonly used in plant rooms, ducts and partitions to reduce noise transmission.

Certifications and Quality Systems That Matter in a Wholesale Supplier

When sourcing wholesale mineral wool blankets, verify certifications and quality systems. FUNAS has obtained CCC and CQC national compulsory product certification as well as CE, RoHS, CPR, UL and FM approvals where applicable. The company also maintains ISO 9001 quality management and ISO 14001 environmental management systems. These certifications demonstrate product safety, consistent manufacturing processes and environmental compliance—key markers of a reliable manufacturer and supplier.

How Wholesale Ordering Works: Practical Guide for Buyers

Specifying Your Mineral Wool Blanket

Define the application (thermal insulation, acoustic control, fire protection), operating temperature, required R-value, space constraints and any facing or vapor barrier needs. This helps the supplier recommend the appropriate density, thickness and facing material.

Minimum Order Quantities and Lead Times

Wholesale orders are usually priced according to volume. Lead times depend on production schedules and customization—discuss estimated delivery with the supplier early in the procurement process to align with project timelines. FUNAS's storage and production setup is designed to support both stock and custom orders for industrial clients.

Packing, Shipping and Logistics

For bulk supply, mineral wool blankets are typically compressed and wrapped for efficient shipping and storage, then decompress on-site. Confirm packaging for moisture protection and any special labeling or documentation required for international shipments, especially when shipping to regulated sectors.

Quality Assurance, Testing and On-Site Support

Testing and Performance Verification

Reliable suppliers provide test reports for thermal conductivity, density, fire classification and acoustic performance. FUNAS adheres to recognized test standards and can provide documentation to support compliance and specification requirements.

Installation Guidance and After-Sales Service

Proper installation is crucial to achieve expected performance. A professional wholesale supplier will offer installation guidelines, recommended fixings and on-demand technical support to ensure the mineral wool blanket functions as intended throughout its service life.

Sustainability and Environmental Considerations

Many mineral wool products incorporate recycled content, especially glass wool. Mineral wool is inorganic and does not promote biological growth. Environmental certifications, recycling pathways and low-emission binders are increasingly available—discuss environmental specifications with your supplier if sustainability is a procurement priority.

Cost and Value: Why Wholesale Makes Sense

Buying mineral wool blankets wholesale reduces per-unit cost and ensures consistent material quality across a project. For manufacturers and large contractors, wholesale partnerships with a certified supplier like FUNAS streamline procurement, reduce lead-time variability and enable custom branding or specification control.
