BetonRadiant Styr EPS is a modular panel for radiant heating floor systems and consists in a milled Betonwood cement bonded particle board with high density (1350 Kg/m³), a compression resistance equal to 9000 kPa, and an insulating expanded polystyrene EPS.

BetonRadiant Styr EPS is an excellent solution to obtain a radiant heating floor system with condensing boilers. The system can also be used on the ceiling and for wall-mounted air conditioning, thus eliminating both radiators and air conditioners.

The radiant panel BetonRadiant Styr EPS is a modular system suitable for any finish, ensuring excellent ease of installation and flexibility, which makes it ideal for the realization of radiant floor heating systems.

One of the panels is milled for housing pipes for radiant floor heating systems, while the other constitutes the insulating underlying layer of insulating expanded polystyrene panel, certified CE. The upper panel after laying the pipes and filling the millings is suitable for any surface coating, chosen by the end user.
The two panels are coupled in the factory with a patented system and the wood used in their processing comes from forests controlled by reforestation cycles and pressed with water and hydraulic binder (Portland cement) with high cold compression ratios.

The BetonRadiant Styr EPS panels are also:

• resistant to the outside;
• does not freeze;
• free from formaldehyde, asbestos.

The system is also available in the version coupled directly in the factory with an insulating layer, which improves the radiant capacity of the entire package.
