James Hardie™ vinyl and cork underlay

An internal underlay for vinyl or cork finishes

An internal underlay used over timber, plywood or particleboard floors to provide a smooth base for laying either vinyl or cork.

Provides a flat, solid substrate, that eliminates movement

On top of internal timber, plywood and particleboard substrates, and under vinyl or cork.

Pre-marked and gun-nailable for fast, easy installation

  • The sheet comes with a pre-marked nailing pattern, which reduces the time the installer has to spend working out where to nail. To add to this, it can be gun nailed with underlay gun nails, which speeds up installation.
  • It’s resistant to damage from termites, rot and fire.*
