Coupled panels BetonSilent with high density cement bonded particle boards 1350 Kg/m³ and an insulating panel made with a high performance extruded polystyrene.
The coupled Betonsilent panel is excellent for the insulation in light wall's systems that require a high mass due to thermal displacement, noise reduction and resistance to humidity and mold. The two external panels are composed of high density cement bonded particle board (1350 kg/m³), with a high compressive strength equal to 9000 kPa and certified to fire in class A2. The middle extruded polystyrene panel is highly insulating.
The BetonSilent panel is an element of completion of the light walls with thermo-acoustic insulation inside. It looks like a sandwich panel consisting of two BetonWood type cement bonded particle boards 20 mm thick, between which a 50.5 mm thick extruded polystyrene XPS panel is inserted. The length of the septum is 1200 mm, while the height can vary from 100 to 300 mm.
The rigid insulation panel BetonSilent is therefore made up of three coupled layers in the factory: two high density BetonWood cement bonded particle boards (1350 kg/m³) and very high compressive strength (9000.00 kPa) made of Portland type cement conglomerate and debarked pine wood fiber, and a central layer consisting of an extruded polystyrene panel.
BetonSilent is a vertical element for filling the plenum of false ceilings and elevated floors, essential in order not to compromise the acoustic performance of the partition. In case of use under the raised floor, the partition can be laid without the need for fixing, to allow easy removal in case of maintenance. In case of use above the false ceiling, it is instead necessary to mechanically fasten it to the soffit of the floor.For further thermal and acoustic insulation it is recommended to lay above and below the sandwich, therefore in the surfaces in contact with the intrados of the floor and the paneling of the floating floor, of a strip of natural insulating material Fibertherm Soundstrip in flexible pressed wood fiber. It can be easily seen from the image and the stratigraphy in the data sheet.
BetonSilent is used as: • thermal and acoustic insulation of traditional and elevated floors; • correction of thermal bridges; • thermal and acoustic insulation of false ceilings; • insulated systems for windows and doors; • dry screeds. If you are interested in this type of solution, we recommend that you take a look at our other coupled products in the section Coupled panels.
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.
For this type of cement bonded particle board and extruded polystyrene panel we do not have available sizes and thicknesses; for the order, minimum orders of 300 square meters are required. In any case, we strongly recommend that you contact our technical office.
• 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.
