Loss of heat through floors on concrete surface beds is experienced as a cold underfoot condition, particularly during winter when the supporting soils cool down due to hygroscopic action of water. In order for rooms to be heated or cooled energy efficiently, the floors need to be insulated from the surrounding soil bed to prevent soilbed from being heated.

Where construction, design and / or cost implications prohibit the installation of an inverted roof insulation system, the requirement for insulation is met by fixing IsoBoard to the under soffit surface of the slab as a ceiling.

It’s worth considering retro-fitting an insulated ceiling to an existing building or home. The obvious reason is to control heat flow through the ceiling space, restricting heat from roof system entering the room below, or containing heat within a living or working space.
