The Rock Wool Roof Panel uses stone fibers as the core material. The fibers are bonded together to form a dense yet breathable structure. This structure stops heat transfer while allowing moisture vapor to escape.
Fireproof Performance
Fire safety is the biggest advantage of our Rock Wool Roof Panel. The mineral wool core is non-combustible. It meets A1 fire rating under EN 13501-1 standard.
When exposed to fire, our Rock Wool Roof Panel does not burn. It does not produce toxic smoke. It also prevents fire from spreading to adjacent areas. For a Rock Wool Roof Panel with 80mm thickness, the fire resistance duration reaches over 60 minutes.
Thermal Insulation
The Rock Wool Roof Panel offers superior thermal insulation performance. The mineral wool core has a thermal conductivity of ≤0.045W/(m·K). This means the Rock Wool Roof Panel keeps your building cool in summer and warm in winter.
Using our Rock Wool Roof Panel can reduce your air conditioning and heating costs by up to 10%. For warehouses, factories, and agricultural buildings, this Rock Wool Roof Panel is the most cost-effective solution.
Mechanical Strength
Our Rock Wool Roof Panel is engineered for strength. The steel facings are available in 0.4mm to 0.6mm thickness. The Rock Wool Roof Panel has a load-bearing capacity of up to 150kg per square meter.
The panel length can be customized from 2m to 12m. The effective width is 1000mm. This Rock Wool Roof Panel can span longer distances between purlins, reducing substructure costs.
Water Resistance
The Rock Wool Roof Panel features a hidden joint design. The overlapping system creates a watertight seal. Rainwater cannot penetrate through the Rock Wool Roof Panel joints.
All our Rock Wool Roof Panel products are tested for water penetration. They pass the EN 12865 water tightness test. This makes our Rock Wool Roof Panel suitable for all climate conditions.
Acoustic Insulation
The mineral wool core of our Rock Wool Roof Panel also provides excellent sound absorption. The noise reduction coefficient reaches 0.85. A Rock Wool Roof Panel can reduce external noise by 30 to 35 decibels.
This is especially important for buildings near airports, highways, or industrial zones. The Rock Wool Roof Panel creates a quieter working environment.
Installation
Our Rock Wool Roof Panel is designed for fast installation. The panels are lightweight and easy to handle. Each Rock Wool Roof Panel can be cut on site using standard tools.
The self-tapping screws fix the Rock Wool Roof Panel directly to the purlins. The overlapping side joints require no sealant. Two workers can install over 200 square meters of Rock Wool Roof Panel per day.
Certifications
Our Rock Wool Roof Panel is fully CE certified. The mineral wool core complies with EN 13501-1 for fire classification. Our Rock Wool Roof Panel also meets ISO 9001 quality management standards.
