Siccus dry installation

Uponor Siccus dry system - lightweight and easy to work with

Uponor Siccus underfloor heating system is a flexible solution that is characterised by its low construction height and its low weight. The system is suitable for new constructions as well as for modernising old buildings. It is quick and clean to fit, and can be walked on immediately after installation.

The Uponor Siccus range includes Siccus FX and Siccus 12mm:

Siccus FX
An alternative to traditional HEP systems, Siccux FX contains a grooved insulation panel with a prefabricated and applied aluminium foil heat emitting top surface. This allows for a quicker installation and an improved heat performance compared to traditional HEP systems.
