SANDWICH PANEL PWW-SU
PWW-SU wall sandwich panel with a hidden joint is used for the construction of external walls (façades), internal partition walls, and suspended ceilings on single- or multi-span skeletal structures.
The joint is hidden within a specially profiled longitudinal edge, forming a lock characteristic of this system, which ensures a clean and aesthetic façade appearance. The installation of the panels can be carried out both vertically and horizontally; however, in the horizontal arrangement, this system requires additional finishing at the panel joints.The panel’s core is made of mineral wool with a density of 100 kg/m³. Due to its properties, especially its high fire resistance parameters, this panel can be used in the construction of buildings requiring enhanced fire protection.The PWW-SU panel is externally compatible with the PWPIR-SU wall panel, which has a polyisocyanurate (PIR) core.

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) 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.
5) for more details on the General Terms of Sale and Delivery, go to www.paneltech.pl
6) 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
7) other steel types are selected according to application conditions and approved by Paneltech
8) 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.
