Roof panel PW PUR-D / PIR-D


Roof panels PW PUR-D, PW PIR-D

PW PUR-D / PIR-D panel is applied as roofs and roof covers.

The panel is characterized by very good thermal insulation properties and strength, as well as very high fire resistance properties (PW PIR-D)

In particular the PW PUR-D / PIR-D panel 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 in modular width of 1130 mm. The lengths of PW PUR-D / PIR-D panel are from 2000 to 16000 mm and their available thicknesses are: 40, 60, 80, 90, 100, 120, 160 mm. The technical parameters ad properties of the panels are presented in the following table.

4) organic coat selected on the basis of durability and application conditions. Coat selection is carried out
through environmental assessment and basing on an environmental questionnaire completed by the Client,
approved by the steel manufacturer and Paneltech
5) other steel types are selected according to application conditions and approved by Paneltech
6) panels with G – smooth or R – groove facing may include micro-waving, which can affect the aesthetic appeal of the product
