How to insulate under Carpets, Laminate or Vinyl

This step-by-step guide will show you how to easily insulate under carpet, laminate, or vinyl flooring using EcoTec FloorFoam.

EcoTec FloorFoam is ideal for this type of application, as it is designed to increase insulation below carpet, wood, laminate, and vinyl floors. It has a built-in vapour control layer which effectively stops draughts and any form of damp rising into your room. It also provides additional soundproofing between floors. FloorFoam is made from 4mm of high-density polyester foam with a highly reflective true aluminium foil on either side.

Rolling Out and Cutting

Roll out your EcoTec FloorFoam to the appropriate length before cutting with scissors or a sharp blade.

Cut where necessary for any radiator pipes.

Stapling the FloorFoam

Staple all the way around the FloorFoam you have just put down with a Heavy Duty Staple Gun Kit, then trim around the edges for a neat finish.

If the floor is concrete, this can be fixed down with a non-solvent adhesive or double-sided tape instead.

Time for the Second Layer

Proceed with your second layer of FloorFoam, ensuring it is butt jointed next to the first layer — it's important not to overlap the material. Repeat this step as required.

Taping and Sealing

Once you've installed your FloorFoam and sealed it to the flooring, tape the perimeter and butt joints with ThermaSeal Joining Tape. This will prevent moisture and draughts from rising through the floor.

Installing Grippers (Carpet)

If you are laying carpet, fix the grippers into place on top of the FloorFoam — this will not affect its performance. Once done, lay your flooring underlay and cut it directly into place on top of the FloorFoam.

Laying Your Flooring

If installing a vinyl floor, we recommend installing a thin plywood layer of 3–4mm over the FloorFoam — this gives the vinyl a completely solid base to sit on, as per the manufacturer's recommendations. Finally, you can now put down your carpet or laminate flooring and enjoy your warm, draught-free living space.
