建筑级珍珠岩

轻质、防火、高效隔热 — 现代建筑的理想骨料与保温材料。

Fireproof

Service temperature to 900°C+. Non-combustible. Ideal for fire-rated walls, doors, and structural steel protection.

Thermal Insulation

Thermal conductivity λ = 0.04–0.06 W/m·K. Reduces building energy consumption by 20–40%.

Lightweight

Bulk density 70–250 kg/m³. Cuts structural dead load significantly — essential for high-rise and retrofit projects.

Const-Insul · 建筑-保温 — Loose-Fill Insulation

Loose-fill perlite insulation for cavity walls, attic floors, and pipe insulation. Pour-in application — no specialized equipment needed.
