Concrete Walls (dual RFL)

Foilboard insulation can be easily adapted to create dual reflective air spaces in concrete walls to further increase performance.

Foilboard® Insulation Panel installed in concrete walls in multi-residential precincts, commercial projects and apartment high rises increases the R value of the building. Its ground-breaking reflective insulation panel design means it can be applied to provide either a single or dual reflective air space within concrete walls.

By creating dual reflective air spaces, Foilboard® can ensure an extra effective thermal barrier in concrete walls. This creation of two reflective air spaces rather than just one creates an incredible increase in energy efficiency, and much lower cooling and heating bills.

Foilboard®'s unique slimline design also has another bonus. By installing Foilboard® between the concrete panel and the plaster, you are increasing the building's thermal efficiency without losing valuable internal space.

This adaptability makes Foilboard® Insulation Panel the leading insulation product for buildings with concrete walls.
