Suspended timber ground floor insulated between timber Joists

Design and Installation

The simplest way of insulating suspended timber ground floors is to fit Quinn Therm QF between the joists. As this has no impact on floor levels it is a good solution for upgrading the performance of existing timber floors.

  1. Radon barrier on sand
  2. Concrete or gravel cover
  3. Joists and support battens
  4. Quinn Therm QF Boards
  5. Timber flooring on polyethylene slip sheet
  6. Internal finish
