Insulated Floor Coil for In/Above Slab and Joisted Floors

Typical Floor Constructions Used

Solid Floor
Concrete or screeded floors are the most common floor construction into which underfloor heating is incorporated. Floor Coil pipe has been specifically designed to be permanently embedded in a structural concrete subfloor or, more commonly within a screed. In either case, insulation is required directly below the pipework to minimise downward heat losses. The thickness and grade of the insulation varies with the particular design criteria. A clip rail system or staples, or pipe positioning panels can be used to hold the pipework firmly in place in line with the designed layout. Screed depth will vary according to the type of screed used, but for a sand-cement screed the depth is generally no less than 65mm with 75mm being the optimum.

Special screed additives are not required, but if used, will have no effect on the pipework.

Maximum Heat Output: 100 W/m².

Suspended Floor - Heat Emission Plate
A grooved heat emission plate can be used either to span the existing joists, or laid on cross-battens. Heating loops are then laid into the grooves. The floor void must be insulated, either with mineral wool insulation or with solid insulation, for maximum heating efficiency. Standard tongue and groove floor deck is then laid before the final floor covering.

Maximum Heat Output: 70 W/m².
