Method Steps

  1. Roll out EcoTec Floor-Foam

    Starting at one end of the room, roll out the Ecotec FloorFoam to the desired length. We recommend starting in one corner.

  2. Cutting the Insulation

    When you have reached the desired length, simply cut the EcoTec Floor Foam, with a sharp Knife / Scissors. You can also make a slit in the material for radiator pipes too.

  3. Fix the EcoTec Floor-Foam

    Then either Staple / Glue / Use Double Sided Tape, to fix the EcoTec Floor-Foam into place. You can also trim any edges as this point to ensure the floor foam is sat comfortably. If using a Glue we recommend to use a Non-Solvent adhesive, as solvents may effect the Foils.

  4. Proceed with the Next Layer

    Install the next run of EcoTec Floor-Foam and butt the edges. Do not overlap as this will make the floor uneven in places.

  5. Tape and Seal Insulation

    When the whole floor has been covered with the EcoTec Floor-Foam we recommend to tape and seal the butt joints and across the whole perimeter to ensure a complete seal. This will prevent moisture from rising and also prevent drafts.

  6. Laying Carpet?

    Fix grippers in to place, over the EcoTec Floor-Foam. This will not impact the performance of the productl. Proceed to install your carpet underlay and cut in to place directly on top of the Floor Foam.
