Description

Floorclad A is a higher-density, non-combustible stone wool insulation board developed to enhance acoustic performance within separation floors, improving both airborne sound reduction (-55-65 dB) and impact sound control.

With a declared thermal conductivity of λ = 0.039 – 0.040 W/mK and a nominal density of 200 kg/m³, Floorclad A is optimised for acoustic performance. It also provides thermal efficiency and maintains Euroclass A1 non-combustible fire performance.

Manufactured from natural volcanic basalt and compliant with EN 13162, Floorclad A is particularly effective in multi-residential buildings, hotels, and commercial developments where acoustic comfort between floors is essential.

Floorclad A is classified as Euroclass A1 (non-combustible) and is suitable for buildings of any height in accordance with UK Building Regulations.

Typical applications

• Separation floors between residential units
• Floating floor constructions
• Acoustic floor systems
• Multi-storey residential and commercial buildings
• Hotels and mixed-use developments
