PIR wall panels with hidden fastening

Wall panels with hidden fastening and the polyisocyanurate (PIR) rigid foam core show excellent thermal insulation properties, thus allowing to decrease panel thickness.

Thinner panels directly transfer to lower transportation and installation costs. Wall panels made with PIR core are the choice for buildings with very high thermal performance requirements. Additionally, our panels with hidden fastening allow hiding all mounting screw-heads thus helping to obtain a spotless facade. BalPol pays special attention to product quality, therefore multi-layer panels are manufactured under ISO 9001 quality standards, quality control is performed according to EN 14509, and panels are tested in modern European fire research institutes. Additionally, we offer to our customers galvanized or stainless steel screws for mounting panels to metal, wood or concrete constructions, as well as decorative flashings according to the client’s chosen colour.

Design tools

Boost your productivity by automating cladding and flashing design in Revit projects with BEWI BIM models.
Put technical designing work in the generation of cladding in Revit to the hands of this tool and do most of the work automatically.

  • Generates wall cladding from standard Revit walls
  • Splits cladding into equal intervals, by grids or by walls
  • Allows to use wall configurator to build preferred wall type
  • Generates hand-editable walls
  • Works with present walls so one can plan new walls accordingly
  • Presents full details for required support profiles, gaskets, etc.; profiling and connections are very detailed
  • Generates required flashings, including internal socle
  • Calculates necessary quantities and forms price request
  • Allows to modify preferred panel length
  • In English, Lithuanian and Russian
  • And other features.

Works with Autodesk Revit© 2017, 2018, 2019 and 2020.


Additional facade cladding

BEWI offers a new facade cladding profile which can be mounted on wall PIR panels with hidden fastening. This profile supports heavy façade systems which cannot be installed directly on sandwich panels.

Thermo profiles

Thermo profiles for horizontal wall panels installation

Panel thickness Inner dimention (mm) Profile height (mm) Steel thickness (mm)
50 28 20-50 1-1.5
80 58 20-50 1-1.5
100 78 20-50 1-1.5
120 98 20-50 1-1.5
150 128 20-50 1-1.5


  • Tapes to seal between panels and structures
  • Aluminium-butyl tape for hydroisolation between socle and thermo profile
  • Low expansion mounting foam


We offer standard flashings to decorate sandwich panels and non – standard flashings up to 3 meters in length. Balpol will supply all the required flashings for the project to match the panels colour.
