SANDWICH PANEL PWS-S
PWS-S wall sandwich panel with a polystyrene core and a visible joint is designed for the construction of external walls, internal partition walls, and suspended ceilings. This panel is characterized by its lightweight construction, good thermal insulation properties, and attractive price.
The panel can be installed both vertically and horizontally using steel screws, which are fixed through the panel to the building’s structure. The PWS-S panel is fully compatible with the PWW-S and PWW-S LITE panels and is externally and internally compatible with other Paneltech wall panels, such as PWPIR-S and PWPIR-S LITE
The thermal insulation core of the panel consists of in-house produced polystyrene with a density of 12.5 kg/m³. The panel facings are made of profiled, galvanized steel sheets coated with protective paint layers, ensuring durability and an aesthetically pleasing façade. The edge joints of the core have been designed in such a way that they do not require the use of additional sealing materials..

2) average weight of a sandwich panel with 0,5 mm outer facing, including product tolerance
3) fire rating concerning the propagation of fire by the wall when the fire acts towards the outside. This property applies to the Polish territory only and is not CE-marked
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.
