CHH Ply Ecoply Barrier

The Ecoply Barrier system provides a weather tight rigid air barrier for drained and vented cavity systems outside the building frame. It replaces traditional building wrap in the cavity while providing superior structural bracing and forming a strong secondary line of defence against moisture penetration into the building envelope.

Key Features
  • Temporary weather protection to the building envelope prior to cladding installation
  • Fast close in allows for earlier interior finish
  • Provides structural bracing when installed as per bracing specifications
  • Sheets can be exposed to weather for up to 6 months prior to cladding installation for increased flexibility during construction
