Concrete or Screeded Floors

Concrete or screeded floors are the most common floor construction into which underfloor heating is incorporated.

Unpipe pipehas been specifically designed to be permanently embedded in a structural concrete subfloor or, more commonly within a screed. Concrete or screeded floors are the most common floor construction into which underfloor heating is incorporated.

Both Concrete or screeded need insulation directly below the pipework to minimise downward heat losses.

Key Information:

• 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.
