The world's largest supplier of underfloor heating

Water Insulation Boards

Water insulation boards are installed directly below your water underfloor heating system, working to save both energy and money. These boards are perfect and safe for use with hot water systems and provide outstanding thermal performance when used beneath a wet underfloor heating system. Designed with high-grade polystyrene and a bonded 200-micron aluminium heat diffuser, these boards offer enhanced resistance to fire, rot and general corrosion as well as providing excellent acoustic insulation properties which can help reduce noise level in the home.
