Industrial-grade Class A1 Fire-resistant Rock Wool Insulation Rolls

Product Overview

This industrial-grade A1 fire-resistant rock wool insulation blanket is manufactured using selected natural ores (such as basalt and dolomite) as base materials. These are melted at temperatures exceeding 1450°C and spun into continuous inorganic fibers via high-speed centrifugal technology, followed by precise binder application, hydrophobic modification, and pressurized curing. The finished product comes in a flexible roll format, facilitating on-site cutting and installation around irregular shapes.

Regarding fire safety, the product meets the national A1 non-combustible standard, with a melting point exceeding 1000°C. It does not melt, shrink, or drip when exposed to open flames, nor does it emit toxic smoke; it effectively delays fire penetration, buying critical time to protect building structures and equipment. In terms of thermal insulation and energy efficiency, the three-dimensional network structure formed by the interlaced fibers traps layers of still air, effectively blocking heat transfer and helping to reduce heat loss in industrial pipelines or the operating loads of building heating and cooling systems. Regarding noise reduction, the open fiber structure dissipates sound wave energy and offers significant absorption of mid-to-high frequency noise, making it ideal for use in mechanical rooms, power workshops, and areas requiring reverberation control.

This industrial-grade A1 fire-resistant rock wool insulation blanket is highly versatile; it is suitable for applications ranging from internal insulation for building exterior walls and fire-resistant cladding for steel structures to thermal insulation and soundproofing for industrial kilns, thermal pipelines, and marine bulkheads. It is a comprehensive insulation material that balances safety, energy efficiency, and environmental comfort.

Product Features

FAQ

Q1: What are the primary methods for securing rock wool blankets during installation?

A1: Rock wool blankets offer flexible installation options depending on the specific application. Common methods include: the pin-and-washer method (using specialized insulation pins and retaining plates, suitable for large flat surfaces or steel structures), the adhesive bonding method (using specialized adhesives, suitable for lightweight walls or ceilings), and the framing/infill method (fitting the blanket into a light-gauge steel keel framework). We can provide the most suitable installation plan and technical guidance based on your specific site conditions.

Q2: Will the thermal insulation performance of rock wool blankets degrade significantly over time?

A2: No. Rock wool blankets are inorganic materials with stable chemical properties; they do not suffer from the aging or decomposition issues common to organic insulation materials. Provided they are installed correctly and remain free from physical damage or prolonged water infiltration, their thermal conductivity remains virtually constant throughout their designed service life. Our stable fiber structure ensures consistent thermal insulation performance over the product's entire lifecycle.

Q3: What does the surface of the installed rock wool blanket look like? Is an additional protective layer required?

A3: After standard installation, the surface of the rock wool blanket presents a smooth, fibrous texture with uniform coloration. It can be used directly in non-exposed areas (such as above suspended ceilings or inside pipe shafts). However, for areas subject to potential human contact or requiring cleanliness and aesthetic appeal (such as HVAC plant rooms or cleanrooms), we strongly recommend adding a protective layer-such as metal cladding or fire-resistant boards-over the rock wool blanket. This enhances impact resistance and facilitates future cleaning and maintenance.
