The basic element of the EUROPANEL system - the panel, is produced by glueing the OSB boards with a core of stabilized self-extinguishing polystyrene, or alternatively polystyrene modified with graphite with better thermal and technical parameters. The panel has a 42 mm deep mounting groove, which is created by overlapping the OSB boards over a polystyrene core, and serves is used to create panel joints. The panels are produced in six thicknesses, three lengths and four widths.
The advantage of the EUROPANEL system is the certification required by the Act No. 22/1997 Coll. on technical requirements for products. The certification and supervision system of the Research and Development Institute of Woodworking (Výzkumný a vývojový ústav dřevařský, s.p.) with its registered office in Prague, guarantees compliance with the prescribed properties of all elements of the EUROPANEL system to its customers and investors. Since 10 January 201, the EUROPANEL system has been the holder of the European Technical Assessment ETA, which is valid in all EU countries.
Constructions with the EUROPANEL system
Because they are flat constructional parts, which are manufactured industrially with great accuracy, their own structures are very precise. The panels are used to make perimeter walls and supporting partitions and are also used as floor and roof panels. The universal usability of the panels simplifies the design of the constructions and the construction logistics. One type of panels for vertical, horizontal and inclined structures simplifies the assembly works, reduces the need for training and qualification while maintaining the high quality of the construction. The SIP is a “dry construction” technology and does not require any special site and assembly teams.
Assembly of the construction
The assembly of the panels starts at one corner of the construction and continues by connecting the other panels around the perimeter. Once the perimeter of the first above-ground floor is completed, the supporting inner partitions are assembled in a similar way. The entire perimeter ans well the partitions are interconnected by inserting the wooden elements into the mounting groove in the “annular arch” of the first above-ground floor. In the case of one-storey houses, the panels are terminated with an OSB spreading strip, the width of which corresponds to the panel thickness. The structure thus will be covered by the roof structure from lattice trusses.
For multi-storey construction, the construction of the ceiling continues. Ceiling beams are suspended into metal clamps that are attached to the inner boards of the panels. If larger spans are needed, these are supported by a glued laminated wood supported by columns on the rectification patches. The ceiling beams are most often made of a wooden profile with the length of 60x240 mm or of wooden “I” beams. The floor of the second above-ground floor is made of OSB boards with the thickness of 22 mm, which are connected to the tongue and the groove, and through the sealing strips the screws are screwed into the ceiling beams and the perimeter walls. On this floor, a wooden insert element is put into which defines the position of the panel of the second above-ground floor. The assembly of the panels on the second above-ground floor is made as on the first above-ground floor.
This solution simplifies the construction of the roof truss as the rafters are supported only at the joining point, i.e. at a distance of 2,500-3,000 mm. Another advantage is more space in the attic because the insulation of the roof casing is located above the rafters. The construction is very quickly closed and protected against collisions.
Completion of the construction
The gross constructions made of the EUROPANEL panels are very suitable for the subsequent crafts. They are assembled precisely, the walls are smooth, straight, vertical and rectangular. For the installation of windows and doors, precise clean holes are prepared. The contact thermal insulation system is mounted on flat walls. All installations are distributed horizontally in the floors or ceilings. Vertically, the installation is made in gypsum boards and prefabricates, and channels for the electric wiring are prepared in the panels. In most cases, the interior is finished with plasterboard, or gypsum fibre or cement-ceramic boards can be used. The floors on the first floor are cast, or dry floors are used, made of different types of boards. The floors on the second floor are designed as “floating”, so the material with good impact attenuation is laid on the spreading board and the floor covering is directly placed on it.
