Looking for high-performance thermal, acoustic, and fireproof protection for your building projects? Our insulation rock wool products offer industry-leading performance designed for residential, commercial, and industrial applications. Engineered from natural basalt rock and recycled slag, our premium insulation rock wool provides an eco-friendly, highly durable, and cost-effective barrier against extreme temperatures, fire, and unwanted sound.
Selecting the right building materials is crucial for energy efficiency and structural safety. High-density insulation rock wool stands out as one of the most reliable materials in modern construction due to its versatile property set:
Unmatched Fire Resistance: Unlike organic insulation materials, insulation rock wool is non-combustible and can withstand temperatures exceeding 1000 degree. It acts as a passive fire barrier, halting the spread of flames and granting precious extra time during emergencies.
Superior Thermal Efficiency: With a consistently low thermal conductivity rating, insulation rock wool prevents heat loss during winter and keeps indoor spaces cool during summer. This thermal stability significantly reduces heating and cooling expenses.
Exceptional Acoustic Absorption: The open-porous fibrous structure of insulation rock wool makes it an excellent sound absorber. It effectively reduces impact noise and airborne sound transmission between rooms or from the outside environment.
Moisture Resistance & Vapor Permeability: Water-repellent additives ensure that our insulation rock wool resists liquid water while remaining vapor-permeable. This allows moisture to escape, preventing mold, mildew, and structural rot within wall cavities.
Our versatile insulation rock wool boards and blankets are designed to meet diverse architectural and industrial needs:
Exterior & Interior Walls: Applied inside stud walls or as external wall insulation systems (ETICS) to maximize thermal comfort.
Roofing & Ceiling Assemblies: Installed in flat roofs, pitched roofs, and suspended ceilings for continuous soundproofing and heat control.
Floor & Floating Floor Insulation: Placed under floorings to dampen footstep noise and prevent thermal bridging.
HVAC & Industrial Piping: Engineered specifically for high-temperature industrial equipment, boiler walls, and HVAC ductwork requiring specialized insulation rock wool lagging.
To ensure your project meets strict international building codes, our insulation rock wool adheres to high manufacturing standards:
| Property | Value / Standard |
| Material Composition | Natural Basalt Rock & Recycled Minerals |
| Density Range | 40 kg/m3 to 160 kg/m3 |
| Thermal Conductivity (λ) | ≤0.034−0.040 W/m⋅K |
| Fire Classification | Class A1 (Non-combustible) |
| Melting Point | >1000∘C |
| Water Absorption | <1.0 kg/m2 (Partial immersion) |
When installing insulation rock wool, proper handling ensures both safety and optimal performance:
Prep the Area: Ensure framing or surfaces are dry and clean before putting the insulation rock wool slabs in place.
Precise Cutting: Use a long serrated knife or insulation saw to cut the insulation rock wool slightly oversized (by about 10mm) to create a tight friction-fit without gaps.
Wear Protective Gear: Always wear long sleeves, safety goggles, and a dust mask when handling high-density insulation rock wool to avoid temporary skin or respiratory irritation.
Both offer great performance, but insulation rock wool offers higher density, superior sound dampening, and significantly better fire protection compared to standard fiberglass batt insulation.
No. Thanks to its rigid mineral fiber matrix, high-quality insulation rock wool maintains its structural integrity and thickness over decades without sagging or shrinking.
Yes, insulation rock wool is made from natural stone and can be fully recycled at the end of its lifecycle, making it an environmentally responsible choice for sustainable green building projects.
