Underfloor heating and cooling

Siccus dry installation

Lightweight design; perfect for suspended timber floors

Uponor Siccus underfloor heating has been developed for use with suspended timber floors. The system is suitable for new constructions as well as for modernising old buildings and results in a minimal construction height of 55 mm. It is quick and clean to fit, and can be walked on immediately after installation. All conventional floor coverings such as tiles, parquet, carpet and plastics with a maximum thermal resistance of Rλ,B = 0.15 m2K/W, are suitable.

Uponor Siccus comprises just four components; mounting sheet, heat conducting plate, heating pipe and PE foil. It is light in weight: only 25 kg/m2 including the floor load distribution sheet. This is a real engineering bonus, especially for wooden joist constructions. The low-mass floor construction allows fast response temperature controls. The integral pipe guide channels in the Uponor Siccus mounting sheet hold the heat conducting plates and heating pipes. The mounting sheet is flexible to use, easy to cut and pre-fitted with channels in the ”header area” for Uponor PE-Xa and MLC pipes.


There are three heat emission plate options available, which can suit timber floor applications:


  • HEP300- For use with timber suspended or battened floors with joists/supports at 300mm centres. 20mm PEX pipe only. 
  • HEP400- For use with timber suspended or battened floors with joists/supports at 400mm centres.
  • HEP411- For use with sprung timber floors with battens spaced at 411mm centres, such as Junckers Unobat and Blubat Sports Floor Systems, suspended or battened floors with joists/supports at 411mm centres. 20mm PEX pipe only.
