Rock Wool Boards for Insulation

---

Overview

GSK Global FZC L.L.C. supplies premium rock wool insulation boards, compliant with BS EN and ASTM standards, suitable for façade, HVAC, industrial, and infrastructure applications.

Product Description

Rock wool boards are rigid or semi-rigid insulation panels designed for:

• Thermal insulation in building envelopes
• Acoustic control in walls and ceilings
• Fire protection in façade and partition systems

They are available in various densities and thicknesses to suit different performance requirements.

Material Properties

• Made from basalt rock and recycled materials
• Non-combustible inorganic fibers
• Water-repellent yet vapor-permeable structure
• Dimensionally stable under temperature variations

Key Performance Features

Thermal Insulation

• Low thermal conductivity: 0.034 – 0.045 W/m·K
• Improves building energy efficiency

Fire Resistance

• Non-combustible material
• Fire classification up to Euroclass A1 (BS EN 13501-1)
• Withstands temperatures exceeding 1000°C

Acoustic Performance

• Excellent sound absorption properties
• Reduces airborne and impact noise

Moisture Resistance

• Water-repellent while allowing vapor diffusion
• Prevents condensation and mold formation
