SANDWICH PANEL PWPIR-SU

Wall sandwich panel with visible joint PWPIR-SU is used to construct external walls and internal partitions in the single- or multiple-span shell structure.

The link is hidden in a suitably profiled longitudinal edge of the panel, forming a locking mechanism characteristic for this system, creating an aesthetic appearance of the facade. The panels can be installed both vertically and horizontally, however, in the horizontal layout, the system requires additional panel jointing treatment.

¹⁾length depends on the color of the external facing and the thickness of the panel
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⁾ for more details on the General Terms of Sale and Delivery, go to www.paneltech.pl
⁵⁾ 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
⁶⁾ other steel types are selected according to application conditions and approved by Paneltech
⁷⁾ detailed information on the MR – microgroove facing type will be provided at individual request
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.

EXTERNAL PROFILATION:

L – linear

MF – microwave

ML – microlinear

MR – microgroove

G – smooth

C – carbon

INTERNAL PROFILATION:

L – linear

R – groove

G – smooth

External facings of Paneltech sandwich panels are available in a wide range of colors consistent with the RAL color system. The offer of SP 25 polyester linings is divided into standard, typical and untypical colors.
