The HN glass wool roll is made from natural minerals such as quartz sand. After being melted at high temperature, it is centrifugally blown into fibers (with a diameter of ≤ 6 μm) to form a rolled material.

The surface of the glass wool roll insulation can be adhered with aluminum foil or PVC film. It has the characteristics of low density (10 - 72 kg/m³) and low thermal conductivity (0.037 W/(m·K)). It is classified as an A-level non-combustible material and has a safe usage temperature range of -120℃ to 538℃.
