JVP 4×4 panels are available in two thicknesses and four total densities, because not all floors need to provide the same level of performance. Every use has its own expected performance and needs, which must be taken into account to avoid design errors.
Using systems whose performance exceeds actual use does not represent a good safety standard, rather waste in terms of costs, consumption of raw materials, transport costs, installation and maintenance, and load on floors.
JVP 4×4 systems do not require additional cross-members, since they simply rest on the underlying structures. This is how we guarantee performance. There is also a corner-lock solution for each JVP 4× 4 panel allowing it to be screwed into the structure, further improving its performance, even for anti-seismic protection.
