INFO:

Foilboard is a 5 Star insulation product manufactured from polystyrene. It can be used almost anywhere in your house from your floors to your roof.

Its extreamly easy to handle and cuts easily with a stanley knife.

The main use domestically is as an external barrier replacing standard house wrap (fixed to the studs on the outside) and sub floor insulation (fixed to the flooring between floor joists).

Because of its differant thicknesses it can be installed in many places normal batt type insulation can't. One of these type of area's is concrete wall construction where there is a limited cavity for insulation between the concrete & plaster.
