How to Install Foil-Tec on Walls

Difficulty: Easy • 5 Steps

Ecohome Insulation have provided a how-to guide, to demonstrate the correct way to install Foil-Tec Single and Double, in both cavity walls and timber frame wall applications.

Foil-Tec is an Insulating Vapour Control Layer, under 1mm thick. It provides thermal performance, without taking up any space.

Our Foil Tec provides you with vapour resistance, whilst also supporting the thermal performance and overall strength of the property. It is superior to conventional vapour control layers, as it also reflects heat back in to the building too.

Timber Frame

Apply the Foil Tec to the stud. You can install either vertically or horizontally - depending on the wall height. Ensure prior to stapling that is is pulled tight. You want to ensure that the Foil Side (If Single) is facing the adjacent air space.
Tape and Seal

Tape and Seal all of the perimeters and the overlaps, with Thermaseal Foil Joining Tape.
Fix Counter Battens

If you do not have a cavity between the studs, then counter batten with either 25mm by 38mm battens. Ensure the battens are installed around the perimeter of the doors and windows and are installed at 400 centres too. Plasterboard can be fixed to battens.
Plasterboard

Following the manufacturers fixing instructions plasterboard can be fixed to the battens.
Foil Tec on Cavity Walls

Screw directly into the wall behind. If Foil Tec Single - The foil side of the material should face the adjacent air space. All overlaps and perimeters must be taped and sealed using Thermaseal Foil Joining Tape. Counter batten and plasterboard, in the same way you would for your timber wall application.
