Detailed information

Product detailed description

System insulation polystyrene board STIROTERMAL DUO 20 for underfloor heating with a hard PS film. For very high loads.

Note: The price shown is per 1 m2. 

Panel size: 1.12 m2

Pipe diameter: 14 - 18 mm

Flexural strength: 150 kPa

Total thickness: 42 mm

One pack contains 11.2 m2, or 10 boards (with an area of 1.12 m2)

 

The system polystyrene insulation board STIROTERMAL DUO 20 for underfloor heating is suitable for very high loads, industry, car service centres, and production halls.

The reflective film is made of hardened PS plastic with a thickness of 0.6 mm.

All system boards feature a so-called "lock" that guarantees the overlap of each side of the board with the next, thereby preventing concrete from penetrating beneath the polystyrene.

The top of the board consists of octagonal studs (mushrooms) with overhangs that allow quick and easy installation (the pipe won't pop out afterwards) of any pipe with a thickness of 14 to 18 mm.  

On the inside of the board, beneath the studs, there are 5 mm small protrusions that ensure the pipe is perfectly embedded in the screed compound, including from below. This ensures perfect heat transfer to the heating board along the entire circumference of the pipe.

This particular polystyrene insulation for underfloor heating has a lower density than the UHP51 system board, but a higher profile. It's up to the customer which board they choose. It is mostly a matter of the comfort of laying the pipe into the polystyrene and the load.

dobrý deň. Protherm alebo bosch, ktoré by ste mi doporučili ako keď chcem zostavu aj s bojlerom, dakym 100 litrovým. Som z Očovej, sem chodíte?

Dobrý deň prajem, obe značky sú kvalitné, ale Protherm je slovenská voľba s dobre rozvinutou servisnou sieťou, čo môže byť výhoda. Ak uvažujete nad zostavou s bojlerom okolo 100 litrov, pozrite sa napríklad na Protherm Panther Condens + zásobník WE 100 ME - toto je kompletná zostava priamo u nás. Čo sa týka dovozu do Očovej - my sme e-shop, tovar doručujeme prepravnou spoločnosťou na adresu, montáž neposkytujeme. Odporúčam nájsť si miestneho inštalatéra, ktorý montáž zaistí.
