LowBoard RdB is a low build up underfloor heating system and acoustic separation. It is designed to dampen vibration and attenuate impact and airborne sound passing through floors with minimum loss of floor height. The system can be laid on solid or timber floors and is supplied with edge isolation strip.

The LowBoard RdB panels comprise of a 15mm moisture resistant high-density wood board with integral 8mm acoustic IsoRubber. As per our standard LowBoard 15 product the wood board layer has grooves routed to accept 12mm pipe and an aluminium layer bonded to the top which acts to spread the heat through the floor. The panels are laid in a brick pattern with the pipe installed by piercing through the soft temper aluminium diffuser into the multi directional channels. A finished floor deck or minimum 6mm ply, MDF or similar is floated or mechanically fixed over the LowBoard RdB panels to complete the floor.
