ECOBEAD® PLATINUM® Cavity Wall Insulation

Benefiting from the excellent environmental aspects of EPS it is installed by approved installers, is fast to install with no waste, and is suitable for improving the thermal performance by making substantial contributions to reducing CO2 emissions and improved energy efficiency of both new build and existing buildings.

The EPS beads are blown into the wall with a specially designed adhesive to hold the bead together inside the cavity providing a full fill insulation solution. The unique flow of bead coupled with its lightness enables the insulation to fill the smallest spaces ensuring all possible areas are filled.
