sandwich panel pwpir-S LITE
Sandwich wall panel with visible joint PWPIR-S LITE is used to construct external walls and internal partitions in the single-or multiple-span shell structure.
The panels can be installed both vertically and horizontally. Unlike PWPIR-S, its core consists of stiff polyisocyanurate foam (PIR) with a density of about 35 kg/m3. Despite a lower density, the panel is characterised by good thermal insulation and strength, however some micro-unevennesses are likely to occur on its surface.
Therefore it’s not recommended to use the panels in facilities where high aesthetics is required. PWPIR-S LITE panels are compatible with polyisocyanurate core wall panels PWPIR-S, with mineral wool core type PWW-S/ PWW-S lite and with wall panels with expanded polystyrene core type PWS-S.

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) applies to horizontal layout
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
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:
INTERNAL PROFILATION:
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 colors.
