Unitherm Heat Distribution & Decoupling Board

• Optimized heat distribution for underfloor heating systems
• Stress-relieving underlay
• Reduces impact sound
• Aluminium layer rapidly spreads heat across the finished floor surface

Heat-distributing, decoupling and impact sound-reduction board for installation with underfloor heating systems in internal areas. It forms a stable, heat-conductive receiving surface for ceramic tiles, natural stone, parquet and engineered wood flooring.

The 4.5 mm board is particularly suited to renovation and refurbishment projects where build-up height is restricted. Installed over the prepared UFH surface, the integrated aluminium layer spreads heat evenly across the floor, helping to reduce temperature variation and improve heat transfer to the final covering. The board also provides a decoupling layer between the heated substrate and the floor finish. An impact sound reduction of up to 14 dB was achieved in the tested ceramic tile build-up described under Technical data.
