Fire Prevention

KERUI calcium silicate boards are a non-combustible A1 grade material, so in the event of a fire, boards will not burn or produce toxic smoke.

Waterproof Performance

KERUI calcium silicate boards have good waterproof performance. It can still maintain stable performance in highly humid places without swelling or deformation.

High Strengths

KERUI calcium silicate boards have high strengths; they are solid and reliable, hard to be damaged and broken.

Dimensionally Stable

KERUI calcium silicate boards are produced with advanced formula and under strict quality control. The wet expansion and dry shrinkage of the boards are controlled within the ideal range.

Heat and Sound Insulation

KERUI calcium silicate boards have good heat and sound insulation effects.

Long Service Life

Heat and Sound Insulation calcium silicate boards are stable, resistant to acid and alkali and corrosion, free from damage by moisture or insects, and can guarantee a long service life.
