Ethafoam® 2222Acoustic Insulation Foam

Ethafoam® 2222 is a closed-cell polyethylene foam material designed for use as a resilient acoustic insulation layer in concrete floor structures.

Key benefits include:

•Superior impact sound insulation–conformstoEuropeanBuildingStandards.

•Minimal moisture retention–closed-cellstructureallowsuseinhumidenvironments.

•Lightweight–easytoinstall.

•Low profile installation–minimalincreaseinfloorheight.

•Ageing resistant–formulatedtowithstanddegradationcausedbyalkalineinconcretefloors.

•Highly resilient–withstandstherigoursofan on-siteenvironment.

•Versatile–canbeinstalledassingleormultiplelayersdependentonspaceandperformancerequirement.
