Product overview

Where is it used?

  • Cemwood CW2000 can be used as an insulation fill under wet or dry screed materials, under floating timber floors or under the Lithotherm underfloor heating system.
  • It can also be used within timber floor structures to reduce sound transmission and increase thermal insulation.
  • Suitable for new build or refurbishment projects.

How is it used?

  • Areas should be dry and free of debris and moisture for maximum effectiveness.
  • The Cemwood CW2000 comes in sacks and can be simply poured in to place and levelled off.
  • The easiest way to instal is to set up rails, using timber battens or metal pipes and level off with a long straight edge.
  • Once levelled, carefully remove rails and fill in voids.
  • Before laying a timber floor over, add a layer of 22mm UdiTOP wood fibre boards to spread the load and prevent any granules getting in to the T&G joints in the flooring.

How much will you need?

Cemwood CW 2000 has a density of 0.36kg per mm per m² (1mm thickness over 1m²). Each 18kg bag (50 litres)  will cover up to 1m² at 50mm thickness or 5m² at 10mm thickness which would be the minimum thickness.
