Brief Description:Sound-absorbing rock wool board is A1 non-combustible basalt fibre insulation for equipment rooms, fan rooms, power distribution rooms and pump rooms. It provides efficient full-spectrum noise absorption, with optional hydrophobic treatment and sturdy structure for long-term service. Custom sizes and factory direct supply are available.

Haochen Sound‑Absorbing Rock‑wool Board is produced using premium natural basalt ore as the primary raw material. Under high‑temperature melting, high‑speed fibre spinning and high‑pressure curing, a continuous, uniform three‑dimensional porous fibre structure forms inside the board. Combining Class A1 fire resistance, high‑efficiency sound absorption and noise reduction, plus constant‑temperature thermal insulation, it acts as a specialist fire‑resistant acoustic infill panel for industrial equipment rooms, fan rooms, power distribution rooms, air‑conditioning rooms and pump rooms. It is widely used in integrated noise control, fire protection and energy‑saving thermal insulation projects across diverse industrial buildings.

Industrial equipment rooms, fan rooms and power distribution rooms host continuously operating machinery with high noise emissions, and represent critical fire safety zones within buildings. Conventional insulation boards commonly suffer from low sound absorption efficiency, poor flame retardancy, moisture‑related performance failure and loose fibre structure, failing to satisfy the dual requirements of equipment noise reduction and fire safety compliance. Haochen specialist sound‑absorbing rock‑wool board for equipment rooms utilises its 3D interlaced porous fibre damping structure to dissipate sound wave energy efficiently. It absorbs medium‑to‑high frequency noise and mechanical vibration noise generated by running equipment, preventing outward noise propagation. The board achieves Class A1 non‑combustible classification: it will not burn under direct flame exposure, creates no molten droplets and emits no toxic smoke. It performs reliably under the harsh operating conditions of power rooms, fan rooms and chiller rooms, resolving core engineering pain points such as excessive noise and non‑compliant fire safety in industrial plant rooms.

1. Core Advantages by Application Scenario

1.1 Acoustic Rock‑wool for Industrial Equipment Rooms

Pump rooms, chiller rooms and power rooms contain continuously running plant that generates persistent vibration and airborne noise. Haochen sound‑absorbing rock‑wool board can be used for cavity filling in partition walls, acoustic ceiling layers and noise‑reduction wrapping around equipment enclosures, attenuating airborne and structure‑borne vibration noise on multiple levels. Hydrophobic treatment is available as an optional upgrade. Hydrophobic‑grade boards resist erosion from pipeline condensate and humid air within plant rooms; they resist water absorption, pulverisation and mould growth, retaining stable acoustic performance over long‑term service. Ideal for the long‑term, high‑load, high‑humidity operating environment of equipment rooms.

1.2 Sound‑Absorbing Rock‑wool for Fan Rooms

Centrifugal and axial fans produce high‑intensity aerodynamic wind noise and mechanical resonance during operation. Enclosed fan rooms easily suffer from reverberation and overlapping echo. This product features fine, evenly distributed fibres and a high sound absorption coefficient. When fitted to fan room walls and within ceiling cavities, it efficiently absorbs high‑frequency wind and turbulence noise from fans and significantly reduces internal reverberation. Easy to cut and flexible to install, it integrates seamlessly with light‑gauge steel acoustic stud systems, ensuring full, tight fitting and substantially improving the room’s acoustic environment.

1.3 Fire‑resistant Acoustic Rock‑wool for Power Distribution Rooms

Transformers, distribution cabinets and other electrical plant emit continuous low‑frequency steady‑state noise during operation. Power distribution rooms are classified as primary fire safety zones in buildings, with mandatory material fire rating requirements. Haochen specialist fire‑resistant acoustic rock‑wool for power rooms delivers noise reduction and fire separation in one product. As an infill substrate for partition walls and ceilings, it blocks transmission of low‑frequency electrical noise while forming a continuous, intact fire barrier to slow flame spread. It fully meets fire safety design standards and final acceptance criteria for electrical equipment rooms.

2. Core Product Performance Features

Class A1 Fire Resistance, Compliant with Strict Plant Room Fire Safety Standards

Made from pure inorganic basalt ore, the board achieves the Class A1 non‑combustible building material rating. It is non‑combustible, produces no burning droplets and releases no toxic smoke when exposed to fire, with robust fire stability. Suitable for high‑grade fire safety zones including power distribution rooms, fan rooms and equipment rooms, it readily passes fire inspections for all types of industrial projects.

Three‑Dimensional Porous Structure, Broad‑Band High‑Efficiency Sound Absorption & Noise Reduction

The interlaced, interconnected 3D fibre pores create a natural acoustic damping structure. It targets full‑spectrum industrial noise, including low‑frequency equipment vibration, mid‑frequency operational noise and high‑frequency wind noise. It effectively reduces room echo, reverberation and cross‑transmitted noise, delivering consistent, long‑term noise reduction performance.

Optional Hydrophobic & Moisture‑Resistant Treatment for Condensation & Humid Environments

Standard boards are general grade; hydrophobic, moisture‑resistant and anti‑condensation treatment is available as a custom process. Hydrophobic‑grade boards block condensate vapour and humid air ingress in plant rooms, eliminating risks of water uptake, degraded acoustic performance, pulverisation and deformation. Sound absorption, fire resistance and thermal insulation properties remain stable year‑round.

Consistent Board Formation, Fast & Convenient Site Installation

High‑pressure curing creates flat boards with a compact structure. Cutting produces minimal loose fibres and little slag shedding. Panels can be precision cut and jointed to meet on‑site construction requirements. Fully compatible with light‑gauge steel acoustic partition walls and ceiling cavity filling methods for clean, standardised installation and improved work efficiency.

Combined Thermal Insulation & Noise Reduction for Energy Savings

While delivering powerful noise reduction, it also blocks conductive heat transfer, cutting equipment energy consumption and temperature fluctuations inside equipment rooms. It combines sound insulation, fire protection, thermal insulation and moisture resistance in a single multi‑purpose material, helping reduce overall project costs.
