BetonRadiant styr XPS is a modular radiant system for underfloor heating consisting of a high density cement bonded particle board and high compressive strength which also acts as a stiffening structure. On the upper face it has a series of small cylinders which allow correct laying of the pipes for radiant heating.
An insulating layer of extruded polystyrene is coupled to the underlying part, which further improves the thermal displacement compared to the standard BetonRadiant product.
The BetonRadiant styr XPS panels constitute an excellent solution for having a radiant floor heating system with condensing boilers. The system can also be used on the ceiling and wall, thus eliminating both radiators and air conditioners.
The BetonRadiant styr XPS panel, as already explained, is mostly composed of cement bonded particle board which offers the advantage of having a specific heat c= 1.88 kJ/kgK, which makes the panel an entire radiant mass. This highly improved value compared to plaster fiber sheets allows for a uniform distribution of heat; moreover, this particular panel is coupled, in the lower part, to an insulating layer in extruded polystyrene. The coupling takes place directly in the factory and allows for greater thermal and acoustic insulation.
If you are interested in this type of solution, we recommend that you take a look at our other radiant products in the section Radiant heating system.
The BetonWood cement bonded particle board is also made exclusively with wood from controlled forests in compliance with the FSC directives (Forest Stewardship Declaration).
The cement bonded particle board has so many advantages, including:
• very high compression resistance;
• high resistance to climate change and frost;
• insects and fungi are unable to attack or damage it;
• thanks to its physical and mechanical characteristics, the product is considered one of the best materials for light weight constructions;
• incombustible (A2 according to the DIN 4102 Standard);
• free of formaldehyde and free of asbestos, asbestos etc .;
• free of recycled inks (present in materials with recycled cellulose);
• resistant to atmospheric agents;
• workable with wooden tools;
• high flow rate;
• recyclable, ecological, respects the environment;
• construction material tested and authorized according to the European standards in force.
The extruded polystyrene XPS panels are characterized by:
• very effective protection against the summer heat, due to the remarkable intrinsic insulating properties;
• high capacity to absorb ambient humidity, which constitutes a natural hygrometric regulator system;
• quality guarantee, thanks to continuous checks and tests carried out according to the European standards in force.

It is possible, on request, produce different formats for a minimum quantity of 300 square meters.
It is also possible, on request, to make housing millings for pipes larger than 14 mm (standard size), up to a maximum of 17mm. With a price increased by 5%.
• the delivery of the material is normally carried out by lorries, considering the high mass of the pallets it is advisable for the recipient to have suitable equipment and mechanical lifting means with a minimum capacity of 35/40 quintals for unloading the goods;
• it is advisable to deposit the boards overlapping them one on top of the other and in order to keep them in a horizontal position, with square section supports and a minimum spacing of 80 cm;
• the transport of the single slabs must be done by cutting, never horizontally;
• avoid direct exposure to sunlight and adequately cover the material to avoid excessive accumulation of dust;
• the pallets are equipped with an upper protective plate, which must be repositioned each time above the other boards and ballasted at the top to avoid distortion of the plates below it.
