Areas of application:   


Unlike many other underlays on the market, REGUPOL sonus multi 3 is ideal for use under resilient floor coverings as it contains NO rubber - thus preventing plasticizer migration - a very important consideration when installing vinyl, linoleum, marmoleum or other resilient floor surfaces. Plasticizer migration can cause resilient floor coverings to discolour and become brittle. Avoid this problem by using a product such as REGUPOL sonus multi 3 which is specifically designed to circumvent these problems.

So, if REGUPOL sonus multi 3 isn't made of rubber, what is it made of?.... Regupol REGUPOL sonus multi 3 is manufactured from high quality, light weight PUR foam granulates and cork, bound with polyurethane.  Examples of resilient flooring include vinyl, rubber, pvc, marmoleum and linoleum. Resilient flooring is basically any floor covering that has some 'give' or 'flex' without cracking, and provides some degree of cushioning when a load is placed upon it.


  • Offers long term performance without collapse or bottoming out.

  • Prevents plasticizer migration - WHY? - because it contains NO rubber.

  • Minimal creep, even under high loads.

  • PVC Free

  • Low VOC and low odour

  • Resistant to ageing and deformation.

  • Quick and easy to install.

  • Minimises construction heights.

  • A Good Environmental Choice Australia Certified sustainable product (GECA)

  • High quality and exact material thicknesses.

  • Made in Germany from recycled, lightweight material

  • Suitable for use with under floor heating.

  • Protects expansion joints.

  • Sanded on one side.

  • Limits sound transference.

  • Cushioning qualities make flooring comfortable underfoot.

  • Proven durability.

  • Manufactured and Certified to OHAS 18001:2007, DIN ISO 9001:2008, DIN ISO 14001:2004 Management Systems.

  • Regupol is a Natspec product partner.
