Product Specifications
The glass wool insulation roll is manufactured via centrifugal spinning to produce long fibers with an average diameter of 5-8 microns, ensuring a recovery rate of up to 99% after vacuum unpacking. It exhibits a thermal conductivity typically ranging from 0.038 to 0.044 W/(m·K) depending on density, effectively reducing heat transfer. The material is rated Class A non-combustible and is treated for a hydrophobicity rate exceeding 98%, preventing moisture retention that could degrade insulation performance or cause corrosion on adjacent metal surfaces.
Application Areas
This flexible material is the primary standard for insulating Pre-Engineered Buildings (PEB) and steel structure roofs, where it is unrolled over purlins to cover vast spans quickly. It serves as external wrapping for HVAC duct systems to control temperature and prevent condensation. It is also widely used in poultry farms and warehouse ceilings where lightweight, cost-effective thermal control is required.
Certifications
Production adheres to the ISO9001 quality management system to ensure consistent fiber quality. The products have secured CE and SGS certifications, verifying compliance with international fire safety and thermal resistance standards to facilitate smooth customs clearance.
Factory
Our facility operates two standardized lines with an automated batching system, increasing output capacity threefold to handle high-volume demands. We utilize advanced vacuum packaging technology for the glass wool insulation roll, compressing the volume by a ratio of up to 1:6 to maximize container loading efficiency. We offer customization for roll length, density (typically 10-48kg/m³), and factory-applied facings, with production data tracked via batch numbers.
FAQ
Q1: How does the vacuum packaging affect the product's thickness upon arrival?
Our glass wool features high fiber resilience. Once the vacuum packaging is opened, the roll will recover to its original design thickness within 24 hours (recovery rate ≥98%). We recommend shaking the roll slightly to accelerate fiber expansion.
Q2: Can you supply the rolls with factory-applied facings?
Yes, we provide online lamination services. Common facings include FSK (Foil-Scrim-Kraft) for vapor barriers in steel buildings, as well as white vinyl or aluminum foil, which reduces on-site labor costs.
Q3: What is the maximum length you can produce per roll?
To minimize joints in large steel structures, we can customize roll lengths up to 30 meters, depending on the thickness and density, while keeping the weight manageable for manual handling on site.
