Insulation Underlay
HARO Silent impact-sound insulation
The right underlay changes how a floor feels and sounds. Laid between the subfloor and a floating floor, HARO Silent acoustic underlays cushion every step, cut impact and room noise, and protect against residual moisture.
Choose a loose underlay for a floating install, or have Silent Pro bonded to the planks for a one-step lay with no hollow spots.
