Product Information
Glass wool is a lightweight, inorganic thermal insulation material produced from natural minerals—such as quartz sand, soda ash, and borax—by melting them at high temperatures, centrifugally spinning them into fibers, and bonding/curing them with a thermosetting resin. It features a fluffy, fibrous structure and offers advantages such as low weight, thermal insulation, sound absorption, Class A non-combustibility, and ease of installation; it is commonly available in three forms: glass wool blankets, glass wool boards, and glass wool pipe sections.

I. General Core Properties
Fire Rating: Class A non-combustible; high-temperature resistant; produces no smoke, toxins, or flaming droplets when exposed to fire
Thermal Insulation: Low thermal conductivity (approx. 0.030–0.040 W/(m·K)); excellent energy-saving performance
Sound Absorption & Noise Reduction: Porous fibrous structure; excellent absorption of mid-to-high frequency noise
Lightweight & Flexible: Low density and light weight; imposes minimal structural load
Water-Repellent & Moisture-Resistant: Treated for water repellency; low water absorption; resistant to mold and rot
Chemical Stability: Resistant to acids, alkalis, and aging; immune to insect damage; long service life
Eco-friendly & Safe: Formaldehyde-free or low-formaldehyde; no dust pollution; easy to install
