Benefits

  • Ecoboard offers a simple composite overlay solution for new and existing floors.

  • Extremely quick and easy to install.
  • Closed cell resilient layer allows internal non-loadbearing partitions to be built directly off the floating floor saving labour, wastage and maintaining acoustic integrity.
  • Ecoboard is only 23mm thick making it easy to marry up to existing stairs on refurbishment projects.
  • Shallow footprint reduces brick coursing compared to some timber floor solutions.

  • Option of 19mm plank within the system offers even greater peace of mind and may improve performance by 3-5 dB.

Typical applications

  • Any new build or refurbishment timber separating floor pplication such as apartments, hotels, student accommodation, care homes etc.
  • Perfect when existing stair heights and doorways etc need consideration.
  • Excellent alternative system for those wishing to Pre-Completion Test with confidence.

*Further improvements can be made by placing 19mm Gypsum based plank over the floorboards before installing the E-Cousti Ecoboard.
