How to Insulate a Concrete Floor

Difficulty: Easy • 3 Steps

How to Insulate a Concrete Floor using EcoTec FloorFoam Insulation. FloorFoam is a 4mm dense true aluminium foil and foam membrane to be used under Carpets & Laminate.

EcoTec FloorFoam has a highly reflective foil either side of the foam membrane. These foils will help retain the heat, and stop the cold rising into your home.

If you are going through building control on this project, we would recommend our LABC certified SuperQuilt Insulation. SuperQuilt however requires a min 50mm Batten which will raise the floor. To view SuperQuilt’s guide for concrete floors, Click Here!

FloorFoam is extremely easy to install. FloorFoam will help to retain heat, add a thermal barrier and also significantly reduce draughts and moisture from rising.

Method Steps

  1. Rolling out FloorFoam

    Start by rolling out FloorFoam Insulation either vertically or horizontally on the concrete floor. EcoTec FloorFoam can then easily be cut by using Multifoil Scissors or a Cutting Knife - Both available in our Multifoil Fitting Kit.

  2. Fixing Down Floor-Foam Insulation

    FloorFoam is fixed onto concrete floors by using Thermaseal Double Sided Tape, or Non-Solvent Glue. Ensure FloorFoam Insulation is fully taped and sealed on butt joints on the floor. Also tape FloorFoam around the perimeter. (Thermaseal Foil Tape is provided free of charge in the Insulation Kit). Taping and sealing ensures no draught or moisture can rise up through the floor.

  3. Install Preferred Final Flooring

    Once your concrete floor has been covered with FloorFoam, next you can install your desired flooring. Wood & laminate flooring can be installed directly on top of FloorFoam. We recommend to use a carpet and laminate underlay prior to a carpet or laminate being installed. If a vinyl or lino is being used, we would advise the use of a plywood over the top of the FloorFoam.
