Wall panel with hidden joint PWW-SU1)


Płyty warstwowe ścienne z rdzeniem z wełny mineralnej PWW-SU

Having launched an innovative panel production line, we can finally offer the PWW-SU hidden joint sandwich panel, characterized by full lock and profile compatibility with the PW PIR-SU polyurethane-core wall panel.

The panels are used to construct external walls and internal partitions in the single- or multiple-span shell structure.  The panels can be installed both vertically and horizontally. The core of the panel comprises mineral wool of 100 kg/m3 . Thanks to their properties, i.e. high fire-resistance parameters, the panels can be used to construct buildings with high fire ratings.

In particular PWW-SU / PWW-SU lite panels can be applied in:

  • Industrial buildings,
  • Store houses and logistic centres,
  • Commercial buildings and offices,
  • Food industry facilities,
  • Agricultural objects
  • Sport halls.

The panels can be executed both in standard modular width of 1050 mm, and in non-standard sizes: 1000 mm. The lengths of PWW-SU panels are from 2000 to 10000 mm and their available thicknesses are: 60, 80, 100, 120, 150, 160, 180, 200 mm. The technical parameters ad properties of the panels are presented in the following table.

1) Minimum Production Quantity (MPQ) is from 300 m2 up to 500 m2 and depends on thickness of the panel. In order to verify production possibilities of specific order please contact our Customer Service or Sales Representative.
2) length depends on the color of the external facing and the thickness of the panel
3) average weight of a sandwich panel with 0.5 mm outer facing, including product tolerance
4) fire rating concerning the propagation of fire by the wall when the fire acts towards the outside.
