Roof panel PWW-D1)


Płyty warstwowe dachowe z rdzeniem z wełny mineralnej PWW-S

Having launched an innovative panel production line, we can finally offer the PWW-D roof sandwich panel, characterized by full lock and profile compatibility with the PW PUR-D / PIR-D polyurethane-core roof panel.

The PWW-D panel is intended for roofs and roofing. 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 the PWW-D panels can be applied in:

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

The modular width of the PWW-D panel is 1050 mm. The lengths of PWW-D panels are from 2000 to 10000 mm and their available thicknesses are: 80, 100, 120, 150, 160, 180 mm. The technical parameters ad properties of the panels are presented in the following table.
