  • Improves Acoustic Insulation: Installing carpet cushion not only reduces sound in the room itself but also reduces the transference of sound to rooms that may be below.
  • Improves Thermal Insulation: Carpet cushion provides an additional layer of insulation which decreases heat lost through floorboards, and also reduces the incidence of under floor draughts.  Not only does this create a warmer internal environment but also helps to reduce energy bills during winter climates.
  • Improves Comfort: Carpet cushion significantly increases the level of comfort underfoot, regardless of the quality and thickness of the carpet.
  • Improves Appearance: Carpet cushion is designed to absorb impact and minimise furniture indentations reducing the wear and tear of carpet.  This ensures carpet keeps its fresh new appearance for longer, and extends its overall lifespan.
