Insulation Below Suspended Timber Floors – Sitework

floor insulation

Steps:

  1. In floor insulation, install timber battens to sides of joists*.
  2. Cut boards to allow them fit into the space between joists and place boards on battens for floor insulation before putting on deck
  3. Spread out and install timber flooring.

* The space at the battens top to the joists top will depend on the Ballytherm board thickness and on a service hole specified by the installation plans.

Hints

  • Measure service void or hole before cutting Ballytherm boards to ensure a close cover.
  • Pack insulation heavily in areas between perimeter joists and wall to prevent thermal escape.
  • Cover all service hole with a flexible material.
