Our rock wool roll is manufactured from premium basalt rock. The raw material is molten at 1450℃ and drawn into fine inorganic mineral fibers, then formed into flexible rolled blankets. It is certified A1 non-combustible, the highest fire safety standard, with long-term working temperature up to 650℃. Thanks to its porous fiber structure, it maintains low thermal conductivity to reduce energy loss, while effectively absorbing noise to achieve reliable soundproofing.
This inorganic fiber material resists corrosion, moisture and aging, so it will not rot or mildew even in harsh industrial environments. The soft roll is lightweight and easy to cut on site, perfectly wrapping round pipelines and equipment. Three types are available: plain rock wool roll, aluminum foil faced roll and wire mesh stitched roll. Custom thickness, width and length are supported for heating pipes, boilers, tanks, HVAC ducts and steel structure fire insulation.

The rock wool roll is a high-temperature fireproof insulation material for construction and heavy industry, with core applications including:
High-Temperature Pipeline Insulation: Wrapped on steam pipelines, heating pipes and chemical ducts, it cuts heat loss effectively and prevents scalding, suitable for long-term high-temperature working conditions up to 650℃.
Industrial Boiler & Tank Insulation: Applied on boilers, storage tanks and reaction vessels in power plants, chemical and metallurgical factories, stabilizing surface temperature and reducing energy consumption.
Steel Structure Fire Protection: Used as fire barrier material for steel beams and columns, meeting Euroclass A1 non-combustible standard to delay structural collapse in fire accidents.
Mechanical Room Noise Reduction: Wrapped around ventilation ducts and industrial equipment to absorb mechanical noise, improving the working environment of factories and central machine rooms.
Building External Wall Insulation: Serves as exterior wall thermal insulation and fire isolation belt for high-rise buildings, hospitals and commercial real estate, satisfying strict building fire codes.
Energy-Saving Industrial Projects: Essential material for thermal preservation in thermal power, petrochemical and central heating projects, lowering long-term operation costs of industrial facilities.
We provide one-stop customization service for rock wool roll tailored to industrial pipeline and construction project characteristics:
Size Customization: Custom length, width and thickness (25–150mm) according to construction drawings and on-site installation requirements;
Performance Customization: Adjust density and fiber structure for projects with special high-temperature thermal insulation or sound reduction needs;
Facing Customization: Optional aluminum foil, kraft paper, galvanized wire mesh stitching facing for enhanced moisture resistance, fire resistance and mechanical strength;
OEM /ODM Service: Support brand printing, packaging customization and bulk order parameter optimization for building material distributors and engineering contractors.
We keep stable stock for regular distributors, shorten production lead time and offer preferential prices for repeated bulk orders.
A: The tangled porous basalt fiber structure traps sound energy effectively. Its sound absorption coefficient (αw) reaches 0.75–0.95 at 1000–4000Hz. It greatly cuts industrial airborne noise and reduces reverberation in mechanical rooms and workshops.
A: Width is fixed at 600mm, while length, thickness (25–150mm) can be freely customized. Density ranges from 60–120kg/m³. We also offer aluminum foil, kraft paper and wire mesh reinforced facings.
A: It passes Euroclass A1 non-combustible standard according to EN 13501-1. The basalt fiber melts above 1450℃, without burning or releasing toxic smoke, ideal for high-temperature fireproof projects.
A: The long-term continuous service temperature is up to 650℃, and the short-term peak temperature can reach 750℃, perfectly suitable for steam pipelines, boilers and high-temperature industrial equipment.
