Uponor Siccus Dry Installation features a Lightweight Design’
Uponor Siccus underfloor heating has been developed for use with suspended timber floors and is suitable for new constructions as well as for modernising old buildings. It has a minimal construction height of 55 mm and is quick and clean to fit. 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 for this system.
What does the Siccus system contain and how does it work?
- 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 for fast response temperature controls and 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.
What are the different options for heat emission plates?
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.
