Insulating levelling aggregate – Cemwood CW2000

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.
