MWS – wall sandwich panel with mineral wool core

Wall sandwich panels with high fire resistance


Wall sandwich panels with mineral wool are made of two steel sheet metallic facings and a construction-insulation core layer. The core layer is made of mineral wool (density: 120 kg/ m3). The panels can be fixed to different kinds of structures throughout the whole panel with the specialized screws. Specifically designed and profiled tongue and groove joints guarantee a very good tightness and make the whole structure fireproof

Wall sandwich panels MWS are available in profilings:

  • micro-wave - MWS V panel
  • micro-trapezodial – MWS T panel

Sandwich panel MWS - applications

  • Internal and external walls in different kind of buildings, where high fire resistance is required
  • Warehouses
  • Industrial buildings
  • Commercial buildings
