Jinhua Exterior Insulation Board Manufacturers Wholesale, Where to Buy Jinhua Exterior Insulation Board? Factory Direct Supply Insulation Board for Building Facades, Quality Assured, Excellent Pricing. The Insulation Board is an inorganic fiber board made by high-temperature melting processing, featuring light weight, low thermal conductivity, heat absorption, and non-combustibility. It is widely used in the petrochemical, textile metallurgy, electric power transportation, construction, and agricultural sectors. Particularly in construction, its extensive application has provided strong support and assurance for China's construction of more green buildings.

Primary fire-resistant features:
1. Fire-rated A1, effectively preventing the spread of fire.
2. The size is extremely stable; it will not elongate, contract, or deform in a fire.
3. Withstanding high temperatures, melting point above 1000°C.
4. Does not produce smoke or burning droplets/fragments in a fire.
5. Will not release harmful environmental substances and gases in the event of a fire.

Insulation and heat preservation
Rock wool fibers are fine, long, and flexible with low slag content. Consequently, they have a low thermal conductivity and offer excellent insulation properties.
Sound Absorption and Noise Reduction
Rock wool is an ideal soundproofing material; its large number of fine, long fibers form a porous interconnected structure, determining its excellence as an acoustic absorption and noise reduction material.

Hydrophobic
Water-repellent rock wool products can achieve a water-repellency rate of up to 99.9%; with an extremely low water absorption rate and no capillary penetration.

Moisture-resistant properties
Rockwool has a moisture absorption rate of less than 0.2% in environments with high relative humidity; tested according to ASTM C1104 or ASTM 1104M methods, the moisture content is less than 0.3%.
