These special elements combine advantages of the well known KVH beams and a multi-layer solid panel and allow a really “OPEN” degree of prefabrication. NOVATOP OPEN elements offer an economical and safe solution for diffusionally open roofs and walls and can be supplied in visible quality or clad, at the production stage, with a multilayer board of silver fir or an acoustic panel.
The construction of the element consists of a bottom load-bearing multilayer panel (SWP) onto which the beams (KVH, DUO, TRIO, BSH, I-girders) are glued at 625 mm on center, the beams performing the bearing function. For reinforcement around the perimeter and around openings, transverse reinforcing ribs are inserted. The dimensions and the spacing of the beans can be adjusted according to the requirements of the project. Connection of the boards and the ribs is achieved by gluing and cold pressing. The cavities between the beams can be filled with thermal insulation. OPEN elements can be closed with another breathable material – diffusionally open (e.g. Fermacell, DHF, DFP, etc.).
