ROOF PANEL PWS-D
PWS-D roof sandwich panel with a polystyrene core is designed for roofing and roof coverings on skeletal structures, particularly in buildings where low investment cost is a key criterion.
This panel is characterized by good thermal insulation performance, lightweight construction, and an attractive price. It is fully compatible with PWW-D roofing panels and externally compatible with PWW-D roofing panels with a mineral wool core, as well as PWPIR-D, PWPIR-D LITE, and PWPUR-D roofing panels.
The thermal insulation core of the panel consists of in-house produced polystyrene with a density of 12.5 kg/m³. The external layers are made of galvanized steel sheets coated with organic protective layers, available in various colors and with different properties. The outer side features a distinctive high trapezoidal profiling, ensuring durability and structural integrity.

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) 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 which is classified as fully compliant with EN 14509, annex D
The profiling of sandwich panel is intended to emphasize aesthetic values as well as increase stiffness. Depending on the type of panel, various variants of profiling are available on both sides. The depth of profiling is approximately 1 mm. The exception is the external facing of the roof panels, which has an individual trapezoidal T profile, approximately 2 mm deep.
