A concrete slab system with self supported insulation and method of making
same which comprises a poured-in-place concrete slab with an insulation
board held by metal or plastic C channels. The insulation is held in
place on both sides by C channels. The C channels are in turn embedded
into the concrete slab and as a result, the insulation is attached to the
slab itself. The embedded C channels serve not only to support the
insulation board but also as concrete form-work, therefore, allowing a
variety of ceiling options on the under-side of the panels, while
providing support for the reinforcing steel on the upper side of said
panels. This system may be used for either an inclined or flat slab
design, roofs or intermediate floor applications.
