Rock wool wall insulation roll is a functional rolled product specifically designed for wall insulation systems. Made from natural basalt, it is manufactured through high-temperature melting, fiberization, and precision forming processes. As a core material in the building energy-saving field, rock wool wall insulation roll tightly fills the gaps between wall studs, effectively blocking thermal bridges and enhancing wall insulation performance. Compliant with GB 50176-2016 Thermal Design Code for Civil Buildings, it is suitable for wall insulation projects of various civil and industrial buildings.

Core Performance
Thermal Insulation and Energy Saving
After application, the wall thermal transmittance can be as low as 0.15 W/(m²·K), reducing indoor heat loss in winter and blocking outdoor heat penetration in summer, thus cutting building energy consumption by 35%-45%.
Fire Resistance and Flame Retardancy
Made of inorganic fiber, it is non-combustible. In case of fire, it can effectively delay the spread of flames, gaining 60-120 minutes for personnel evacuation (in line with UL 1043 standard).
Structural Adaptability
With excellent flexibility, it can closely fit the gaps between wall studs and pipelines, achieving a filling rate of over 99% and avoiding insulation dead corners.
Product Advantages
Safety and Environmental Protection: It releases no harmful substances such as formaldehyde or benzene, and produces no toxic smoke when burned, meeting the requirements of green building materials.
High Cost-Effectiveness: Integrating multiple functions of thermal insulation, fire resistance, and sound insulation, it eliminates the need for additional materials, reducing the comprehensive cost of materials and construction.
After-sales Guarantee: Free samples and technical solution design are provided. The production process is fully traceable in real time, and quality issues are responded to and handled within 72 hours.
FAQ
Q: Will wall dampness affect the product performance?
A: With a hydrophobic rate of ≥98%, the product does not absorb free moisture and only allows water vapor penetration. It can be used stably for a long time in environments with relative humidity ≤85%.
Q: What is the service life?
A:In standard building environments, it maintains stable performance without risks of aging or decay. The service life can reach more than 20 years, synchronized with the main structure of the building.
Q: Can the product be customized according to project requirements?
A: Yes. We support customization of product thickness, density, and roll size (length and width) based on specific project scenarios such as industrial equipment insulation or building exterior wall fire protection. The customization cycle is 3–7 working days, and a bilingual technical team will provide professional parameter matching suggestions.
