RUKO HAB-SDS25 1000x950mm Rock Wool Insulation Board 25mm

With a sound absorption coefficient of 0.95 and fire reaction class A1, this rock wool insulation board delivers both acoustic and thermal performance for interior wall and ceiling applications.

Overview

The RUKO GMBH HAB-SDS25 is a 25 mm thick rock wool insulation board measuring 1000 mm in length and 950 mm in width. It is designed for use in interior walls, ceilings, lightweight partition systems, and drywall constructions. The board has a square edge finish and a thermal conductivity of 0.035 W/(m·K), providing effective thermal insulation.

What stands out

• Non-combustible: Fire reaction class A1 per EN 13501-1, making it suitable for fire-resistant constructions.
• Excellent sound absorption: αw = 0.95, reducing noise transmission in partition walls and ceilings.
• Rot-proof and non-hygroscopic: Does not absorb moisture, preventing mold and maintaining performance over time.
• Low water vapor diffusion resistance (μ = 1): Allows moisture to pass through, reducing condensation risk.
