DELTA-FL™ Carpet Underlayment

  • Delta®-FL rolls out to create a water-vapor proof seamless subfloor preventing moisture rise that would damage floor finishes*.
  • Up to 30% increase in floor temperature.
  • Protects floor finishes from moisture.
  • Laminate can be directly installed on Delta®-FL.
  • Instant comfort and warmth.
  • Fast and easy to level and install.
  • Delta®-FL will never rot, unlike other subfloor systems.
  • Unlike 2’ x 2’ panels, there are no open seams that could create mold.
  • Provides an insulation thermal air-gap barrier that separates your finished floor from the concrete floor.
  • Provides a strong even subfloor.
  • Offers minimal reduction in head room, adds only 5/16” (8 mm) height to the floor.
  • Provides a clear drainage path underneath the floor, to allow moisture to move to drains, if necessary.
  • Allows airflow under the floor.
  • Creates a vapor pressure equilibrium between the airgap created by Delta®-FL and the soil/concrete below, stopping the moisture drive into the interior and providing a healthier, less humid climate.
*seams are sealed with Delta®-MOISTURE PROOF TAPE.
