- first and second side panels 12, 14 are provided with alternating ribs 24 and troughs 26.
- the ribs 24 and troughs 26 are configured so that a first side panel of an insulating form element 10 will mate with a second side panel 14 of a similar adjacently disposed insulated form element 10 and thereby prevent egress of settable material through the form elements 10 during formation of the slab.
- the insulating form element 10 also includes one or more utility chases 28, each utility chase 28 being arranged to accommodate utility items such as electrical conduits and/or plumbing pipes.
- a slab of desired size is constructed by disposing a required number of insulating form elements 10 in mating relationship and disposing settable material, such as concrete, on the form elements 10 to a desired thickness.
- each of the present insulating form elements 10 includes a single channel, other arrangements are possible.

- a required number of form elements 10 are disposed side by side such that adjacently disposed ribs 24 and troughs 26 mate with each other, and the form elements are supported at a desired location relative to a building under construction. Concrete is then poured onto the form elements 10 and allowed to set.
- a slab formed in this way effectively defines a series of structural concrete T beams integrated with a thinner flat concrete slab. This reduces weight while maintaining strength. Tapering walls of the channel portion 16 ensures that an insulating layer is mechanically locked to the concrete to provide
- the configuration of the concrete portion of the slab may be easily tailored by modifying the shape of the insulating form elements 10, the thickness of the form elements 10, and/or the depth of the channels 16.

- a 'chair' 70 for example formed of steel material, is included for receiving reinforcing rods during use.
- FIG. 7 A portion of a wall panel 72 formed using the insulating form elements 60 is shown in Figure 7. As with the slab 30 shown in Figure 2, concrete material 74 is poured onto the form elements 60, and reinforcing bars 76 and a reinforcing grid 78 are incorporated into the concrete 74 during the wall fabrication process.
- the wall 72 is fabricated on site by disposing an appropriate number of form elements 60 in mating relationship and pouring concrete material 74 onto the form elements 60 until the channels 68 have filled with material and a concrete panel of sufficient thickness has been defined above the form elements 60. After the concrete material 74 has set, the wall 72 is tilted to a vertical orientation and secured in position relative to the building under construction.
