Stone Wool Insulation Board: Reliable Fire, Thermal & Acoustic Protection

Your Trusted Stone Wool Insulation Board Manufacturer

In response to the common problems of heat loss, fire spread, and noise pollution in building and industrial systems, Xiaolong's high-density rock wool insulation board is made based on the natural volcanic rock melting and spinning process. It has stable performance and strong load-bearing capacity. Even when subjected to heavy loads or long-term high-temperature conditions, it can maintain a complete structure and stable insulation, fire prevention, and noise reduction and control performance. The brand strictly controls the entire production process from raw material fiber processing to board cutting and packaging, ensuring that the density, thickness, and size accuracy of each batch of products are highly consistent, completely solving the problem of performance differences between batches. It is a reliable choice for contractors, distributors, and industrial purchasers.

Core Performance Strengths of Stone Wool Insulation Board

High Compressive-Load Bearing Capacity

· The dense fiber structure resists deformation under mechanical pressure, making it suitable for floor and roof applications that carry ongoing foot or equipment load.

· Board density is available from 60-200 kg/m³, so you can match load requirements without over-specifying material.

Enhanced Moisture-Resistant & Non-Hygroscopic Properties

· The fiber structure repels water while still allowing water vapor to pass through, which helps prevent trapped moisture and mold growth inside wall or floor assemblies.

· Insulation performance stays stable even in humid site conditions or during temporary weather exposure before final cladding is installed.

Superior Thermal & Acoustic Insulation Performance

· Low thermal conductivity reduces heat transfer through walls, roofs, and mechanical systems, helping buildings hold a stable internal temperature.

· The fibrous structure absorbs sound energy, cutting noise transmission in party walls, plant rooms, and floor assemblies.

Durable Long-Term Service Lifespan

· Stone wool does not rot, shrink, or settle over time, so insulation performance stays consistent for the full service life of the building.

· The board resists biological growth and pest damage, reducing the need for early replacement or repair.

Real-World Application Scenarios for Stone Wool Insulation Board

Curtain Wall Fire-Stopping & Infill Assemblies

· Used as fire-stopping infill between floor slabs and curtain wall systems to slow fire and smoke spread between floors.

· Fitted behind spandrel panels to add a thermal break and reduce heat transfer at the building perimeter.

· Selected for high-rise facades where both fire compartmentation and insulation performance are required in one layer.

Raised Floor & Cavity Floor Insulation Build-ups

· Installed under raised access floors in data centers and commercial offices to reduce heat loss and control underfloor acoustics.

· Used in cavity floor systems to dampen impact noise transmission between building levels.

· Applied around underfloor service runs to maintain stable temperatures for pipework and cabling.

External Wall Composite Insulation Systems

· Bonded to masonry or concrete substrates as the core insulation layer in external wall insulation (EWI) systems.

· Combined with render or cladding finishes to improve building envelope thermal performance and reduce energy costs.

· Chosen for renovation projects where adding fire-resistant insulation to existing facades is a priority.

Semi-Exposed Shelter & Canopy Constructions

· Used in semi-open shelters, loading canopies, and equipment enclosures where boards face partial weather exposure.

· Applied in agricultural and light-industrial structures needing basic thermal control without a fully sealed envelope.

· Fitted into modular shelter panels for quick on-site assembly and consistent insulation performance.

Key Buying Queries for Stone Wool Insulation Board

1. Is stone wool insulation board fire-resistant?

Yes. Stone wool fiber does not burn and can withstand very high temperatures, which is why it is widely used in fire-stopping and fire-rated wall applications.

2. Can the board be cut to custom sizes on site?

Yes. Standard boards can be trimmed with normal cutting tools during installation, and Xiaolong also offers factory pre-cutting for large orders.

3. How should stone wool insulation board be stored before installation?

Store boards flat, off the ground, and under cover to keep them dry until installation, especially if they will be exposed to site weather.

4. What order quantities does Xiaolong work with?

We support both bulk wholesale orders for large projects and smaller trial orders for new customers testing the product before scaling up.
