Silica Rock Purification Board Advantages

1. Excellent thermal insulation and energy-saving effect

Class A polystyrene board retains the advantages of traditional EPS foam board with low thermal conductivity and high heat storage coefficient, offering better insulation effect compared to inorganic active thermal insulation mortar, foam glass, etc., available on the market.

2. Safety and fire resistance—Class A flame-retardant material

Silica Rock Purification Board overcomes the flammability drawback of traditional EPS foam board, meeting the Class A fire safety standard for thermal insulation materials.

3. Silica Rock Purification Board has higher strength than rock wool and phenolic boards, is non-absorbent, non-shedding, and easy to install.

4. Superior system performance

Silica Rock Purification Board features a closed-cell foamed spherical molecular structure, is relatively lightweight, and offers good dimensional stability. The system has undergone weathering tests, including 80 high-temperature–water spray cycles and 30 heating–freezing cycles, without blistering, hollowing, or peeling of the surface layer, and without water seepage cracks. Impact resistance reaches 10J for tiles and 10J for coatings, demonstrating excellent performance.

5. Mature craftsmanship

The construction process for Silica Rock Purification Board is the same as that for the traditional EPS board thin plaster exterior wall insulation system. The construction technique is mature, making it easy for workers to install, without the instability issues found in other new material systems.

6. Cost-effectiveness

Class A polystyrene board retains the advantages of traditional EPS foam board, such as "low thermal conductivity, excellent insulation effect, and mature craftsmanship," while being low-cost. Its price is lower than that of similar Class A flame-retardant thermal insulation materials on the market, achieving Class A flame-retardant effects at the price of ordinary materials.
