The Uponor Nubos product line When it comes to underfloor heating and cooling installations in the newly built segment, Uponor Nubos is the all-round system for almost every task, from private residence to public and commercial buildings to industrial construction. The perfectly matching system components of Uponor Nubos enable customised solutions for all floor types, applications and room shapes.

Standardised installation in no time The nub panels provide fast installation that complies with all relevant norms and regulations. The system pipes are positioned and fixed in the nub panels, thus ensuring that they are optimally enclosed in the screed. These features enable complete transmission of the precalculated heating output and they provide a flexible temperature control mechanism – all of which leads to an economical and energy-saving operation.

The Uponor Nubos product line provides comfort and safety at a low price.

Sandwich structure for practical use A cross-sectional view of the Uponor nub panel 14-16 EPS 30-2 shows its sandwich structure. In the upper area a solid polystyrene insulation layer provides robust nubs that can be walked on while laying the pipes. Below this solid layer, an

additional softer layer optimises sound insulation. Thanks to this smart combination, the panel achieves a thermal resistance of RD = 0.75 m2 K/W. The impact sound according to DIN 4109 measures 28 dB, placing it in CP2 level of EPS compressibility classification, where an impact load of 5 kN max. can be applied.

Quick one-man installation Larger system elements of about 1.25 m2 are installed in the usual manner from left to right. Due to the smart cutting and overlapping

technique there is virtually no waste. The installation of each row can start by using spare parts from the previous row.

Expert help for the perfect cut The Uponor cutting tool provides practical help for cutting the panels.

Its carriage guide allows the user to cut three pre-defined accurate lines - not only in the longitudinal direction, but also diagonally. The nub structure on one side of the panel and the grid structure on the other side provide additional guidance.

Uponor nub panel 14-16 Add. Set 30-2 For pipe laying in doorways and distribution areas, Uponor Nubos offers additional panels with an optimised number of nubs. These panels can be easily integrated into the layout as their nubs overlap with existing ones.

This is how a consistently dense surface is achieved even in difďŹ cult and complicated room areas.

Applicable pipe types A range of 4 different pipe types is available: Uponor Comfort Pipe 14 x 2 mm Uponor Comfort Pipe 16 x 1.8 mm Uponor MLCP RED 14 x 1.6 mm Uponor MLCP RED 16 x 2 mm
