50mm Rockwool Thermal RockFloor (sold per pallet)

Thermal RockFloor is a rigid stone wool insulation board designed to improve the thermal performance, sound control, and fire safety of ground and separating floors. Its strong, durable structure provides reliable support beneath screeds and floor finishes while helping reduce heat loss and enhance comfort throughout the building. Suitable for concrete, beam-and-block, and suspended timber floors, it delivers long-lasting performance for both new-build and refurbishment projects.

Benefits

• Enhanced thermal insulation helps reduce heat loss through ground floors and improves overall energy performance
• Stone wool structure provides excellent sound absorption, helping control impact and airborne noise between storeys
• Euroclass A1 non-combustible, offering the highest level of fire safety and contributing to safer building design
• High compressive strength ensures a robust base beneath screeds, floating floors, and floor coverings
• Moisture-resistant and rot-proof, preventing long-term degradation and supporting a healthier floor build-up
• Maintains its thickness and performance over time, even under sustained load or pressure
• Easy to cut and handle, allowing quick installation around services and irregular floor layouts
• Manufactured from natural stone and recycled content, supporting sustainable construction standards

Good to Know

• Suitable for solid concrete floors, beam-and-block systems, and suspended timber floors
• Available in a range of thicknesses and densities to match thermal targets and project specifications
• Can be used beneath floating floors, screeds, chipboard, or other floor finishes depending on system requirements
