Glass Wool Blanket is manufactured using advanced centrifugal technology that transforms molten glass into ultra-fine fibers, bonded with eco-friendly thermosetting resins. Each glass fiber measures just a few microns in diameter, delivering exceptional performance as a fire-resistant, thermal insulation, and acoustic absorption material.
It combines flexibility, lightweight design, and proven insulation performance, making it the preferred choice for HVAC systems, industrial facilities, commercial buildings, and residential projects requiring reliable thermal and acoustic control.

2. How do you ensure the density and thickness consistency?
Our automated production lines are equipped with real-time thickness monitoring and PLC control systems. Every batch undergoes rigorous testing for thermal conductivity and tensile strength, backed by SGS and CE certification to meet international standards.
3. What are the key technical specifications of Liluan Glass Wool Blankets?
Our glass wool blankets feature a low thermal conductivity (≤ 0.034 W/m·K) and excellent sound absorption (NRC 0.80-0.90). They are Euroclass A1 non-combustible, with a density range of 10~48k and thicknesses from 25 to 200mm.
4. Do you provide custom specifications and facing options for bulk orders?
Yes. Standard sizes are in stock for fast delivery. Custom thickness, density, and FSK foil/fiberglass cloth facings are available to meet different fireproof and moisture-proof project requirements.
