Pirtech Roof – roof sandwich panels – polyurethane foam – visible fastening
In buildings with large areas, such as large -scale shops, warehouses, production or sports halls, layered plates specially designed for this purpose are used to cover the roofs. They owe their wide use to several undeniable benefits for investors and contractors – they are easy and quick to install, provide very good thermal, acoustic and fire resistance. They are also an economic material, which has a significant impact on the investment budget.
PIRTECH plates are sandwich panels, whose core is a stiff polyurethane foam of the PIR type, and steel sheets protected with a layer of zinc or stainless steel are used for plates cladding. They are not a structural material, but a protective material. Depending on the purpose – location to the internal or outer wall, for the construction of a cold store or roof, the family of Pirtech products differ primarily in the core thickness and thickness of the sheet, invisible or visible mounts that affect the mechanical and thermal insulation properties of products.
PIRTECH ROOF plates available in Blachy Pruszynski’s offer are intended for roof housing, which is why they are distinguished by, among others Lack of profiling sheet from the inside and the shape of the external surface in the shape of a trapezoid, which allows you to carry high loads, as well as the use in single -span and multi -span systems.
The core of PIRTECH layered panels is a stiff PIR polyurethane foam with a volumetric density of 40.0 kg/m3 ± 3 kg/m3. The production process is implemented by a continuous method on a fully automated line provided by one of the leaders of this industry, Hennecke (Germany). Pentan is used as a foaming factor. Therefore, the production process is environmentally friendly, i.e. a non -destructive ozone layer and does not cause a greenhouse effect. In addition, the components of polyurethane foam are: polyol – polyurethane resin, isocyanate – hardener, activators and additives. Application in single -span and multi -span systems.
Steel sheets protected with a layer of zinc covered with one of the organic coatings or aluminum -zinc coating are used for plate cladding. In addition, cladding made of stainless steel sheet are offered.
The basic thickness of external and internal cladding is 0.50 mm. The thickness of sheets in the thickness range from 0.40 mm – 0.70 mm are also available.

PIRTECH ROOK are models with a thickness of 40 mm to 160 mm:
PWD-PIR 40
PWD-PIR 60
PWD-PIR 80
PWD-PIR 100
PWD-PIR 120
PWD-PIR 160
The basic thickness of external and internal cladding is 0.50 mm, but it is possible to order sheets in the thickness range from 0.40 mm – 0.70 mm if they require their design. PIRTECH ROOK plates have visible fastening.

PIRTECH ROOK boards can be mounted on various types of substrates: wooden, steel or concrete, both in new and modernized buildings.
When connecting roof slabs in the length, it is necessary to cut the upper plate. Pirtech roof plates can be produced with ready undercut in the range from mins 50 to max 300 mm. Just choose the type of undercut that is determined by the direction of assembly:
The total length of the plate covers the selected length regardless of the undercut, as shown by the example: a 6000 mm long plate with a undercut of 200 mm = 6000 mm (core 5800 mm + sheet 200 mm). Blachy Pruszyński performs two types of undercuts:
During assembly, pay attention to the outside air temperature, which affects the aesthetics of the facade and the proper operation of the plate. Installation of boards in light and very light colors is possible in the temperature range from +5 ° C to +35 ° C. Failure to comply with the above guidelines may result in the appearance of surface deformations on the plates and the local loss of stability, for which the manufacturer
does not take responsibility.
Pirtech plates, thanks to a wide range of colors, allow you to achieve consistency with other finishing elements, such as flashing, so it’s worth fulfilling your order at one supplier. The Pruszyński company guarantees each time the implementation of a individual order in the same color (shade), with the complicated coating process there is a possibility of differences in shades between individual supplies. Therefore, as a producer, we take responsibility for color only in the range of one delivery. Here are the colors available in our offer:
In the case of colors that do not find in the table, contact with the technical advisor of Pruszynski is recommended, with the change in the color of the disc can only occur with the consent of the designer. A detailed color palette for PIRTECH PIRTECH PIRTECH SHAT can be found here.
In the case of PIRTECH boards, the designer must take into account the temperature differences between layered panels. Temperature gradients resulting from the temperature difference between external temperature and internal temperature depend on, among others
The minimum length of the plate is 2 m, and detailed recommendations regarding the permissible maximum panel length depending on the color of the cladding are the following table.
length resulting from the reduction of the maximum elongation/shortening of the plate
Detailed information on the length of the discs can be found in our PIRTECH product catalog.
The Pruszyński sheet offer addressed to the institutional investor contains all elements of light tin structures for commercial and utility purposes. From drainage systems, through load -bearing elements to both external and roofing.
Layered boards are valued individually. Therefore, you should send an inquiry by e -mail, providing all the parameters of the discs, their colors, quantity, place of delivery, or information about the required fireproof. It is also good to attach the technical drawings of the facilities to which the investment relates. If something requires supplementing or choosing the right product, our technical or commercial department will contact and ask for specific information.
Excellent functionality and durability of PIRTECH ROOFTOP sandwich panels will correspond to any construction design taking into account the manufacturer’s recommendations and proper performance. We encourage you to contact us and consult with our technical advisers who will help in the selection of models and the length of the panels to best use their features.
Our offer includes a wide range of various variants of PIRTECH layered plates, depending on the application. From wall coverings, including a hidden lock to a special use plate with very high core thickness (use, e.g. in cold storages).
