Foam glass board is a porous inorganic non-metallic material made from crushed glass and foaming agents through processes of crushing, mixing, molding, high-temperature firing at approximately 1000°C, and annealing cooling-2. Its interior consists of numerous uniformly closed-cell pores with a porosity of 85%-95%, forming a honeycomb-like independent sealed structure-2.
Key Features:
Excellent Thermal Insulation: Thermal conductivity as low as 0.05-0.06W/(m·K), delivering outstanding insulation performance-2.
Class A Non-Combustible: Rated as A1-grade non-combustible inorganic material with a fire resistance of over 3 hours, emitting no toxic gases under high temperatures-.
Waterproof & Moisture-Resistant: Closed-cell rate exceeding 95%, volumetric water absorption ≤0.5%, virtually non-absorbent-.
Lightweight & High Strength: Density ranging from 120-500kg/m³ (1/5 to 1/10 the weight of ordinary glass), compressive strength ≥0.5MPa-2-1
Durable & Weather-Resistant: Service temperature range from -200°C to 450°C, withstanding over 200 freeze-thaw cycles and offering a service life of up to 50 years-2.
Main Applications:
Foam glass board is widely used in building exterior wall insulation and roof thermal insulation-2; cold storage, LNG tank, and other low-temperature cold insulation projects-2; pipeline and equipment anti-corrosion insulation in chemical and petrochemical industries-2; as well as wall and ceiling materials for underground projects such as tunnels and subways-2. With its outstanding comprehensive performance, foam glass board is recognized as an ideal insulation material that "lasts as long as the building itself"-19
