Coupled panels made with cement bonded particle boards 1350 Kg/m³ and an insulating panel made with a high performance expanded polyethylene terephthalate.
The coupled BetonStrong panel is excellent for the insulation of dry screeds and walkable roofs that require a high mass due to thermal lag, noise reduction and resistance to humidity and mold. The external panel is in fact 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 expanded polyethylene terephthalate panel is highly insulating with high breathability and moisture resistance.
BetonStrong is an extremely versatile product as it is suitable for multiple applications in construction, since the advantages of two materials are combined in a single coupled: on the one hand, a material with a high mass and high compressive strength, the high-density BetonWood cement bonded particle board on the other hand, an extruded PET panel characterized by lightness, high insulating capacity, easy processing and high compressive strength, indispensable for obtaining an adequate thermal displacement and great noise reduction. Both materials are of excellent quality, processed with the most advanced technologies, subjected to strict process controls, CE marked.
The high-performance BetonStrong insulating panel is a combination consisting of two layers glued in the factory, one in cement bonded particle board and one in expanded polyethylene terephthalate (PET): • BetonWood cement bonded particle board is a very strong material, has a high density of 1350 kg/³ and a very high compressive strength (9000 KPa); it is made of Portland-type cement conglomerate and debarked pine wood fiber, a recyclable, non-combustible material, resistant to changes in temperature and climatic conditions, insects and fungi and atmospheric agents. • expanded polyethylene terephthalate is a structurally strong thermoplastic material perfectly suited in a variety of applications to increase performance and decrease weight. The characteristics of the material make installation very easy and fast even at high temperatures. It has excellent chemical resistance and is compatible with all commonly used resin bonding systems (e.g. polyester, epoxy resins, etc.). With its performance it can be easily used in prefabricated systems.
BetonStrong adapts to any use, within the thermal insulation and is particularly suitable for all cases where there is a strong moisture component and the need for a material with considerable compressive strength. In particular it is used as: • insulation of floors for raised floors; • correction of thermal bridges; • external and internal thermal coats; • disposable formworks; • inverted roofs; • insulated systems for frames, in particular for the insulation of roller shutter boxes; • dry screeds and radiant heating 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.
For this type of cement bonded particle board and expanded polyethylene terephthalate 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.
