防火、轻质、高效隔热 — 珍珠岩是现代建筑的可持续选择。

Why Perlite for Construction?

Non-combustible — fire rating up to 4 hours

Reduces structural dead load by 20–40%

Thermal conductivity as low as 0.04 W/m·K

Sound absorption — NRC up to 0.75

Dimensionally stable — no shrinkage or swelling

100% mineral — no VOCs, no off-gassing
