Paneltech PWPIR-D LITE roof sandwich panel

22 of July '25

PWPIR-D LITE roof sandwich panel is designed for roofs and roofing.

Despite the lower density of PIR foam in the core, the board is characterized by good thermal insulation and strength, but there is a possibility of micro unevenness on its surface. Therefore, it is not recommended to use the panels in objects where high aesthetic qualities are required.

In particular, PWPIR-D LITE panels can be used to build, among other things:

  • warehouses,
  • containers,
  • poultry houses,
  • piggeries,
  • barns.
