Poultry Farm Building Clad with Sandwich Panels — Case Study | BOKKA
Poultry Farm — 100 mm PIR Sandwich Panel Envelope
The project comprised a complete building envelope for a livestock facility intended for poultry farming. Located in Poland, the structure was erected using lightweight cladding technology, with wall and roof sandwich panels of a uniform 100 mm thickness. Broiler houses of this type require an airtight, durable and hygienic shell, which is why the investor opted for prefabricated solutions with a polyurethane core. BOKKA, as the regional distributor covering central and eastern Poland, supplied the full panel package directly to the site.
Design challenge
Farm buildings impose several parallel requirements on the contractor: maintaining a stable internal temperature, resistance of facings to humidity and disinfectants, and compliance of thermal parameters with the WT 2021 Polish technical regulations (U-value ≤ 0.20 W/m²K for walls). A short installation schedule was also critical — poultry production cannot tolerate prolonged construction downtime between rearing cycles.
Solution applied
The project used insPIRe® sandwich panels with a 100 mm PIR core in RAL 9006 (white aluminium). The external walls were executed in the micro-line profile variant, which masks minor installation irregularities and gives the façade a clean, uniform appearance. The PIR core achieves fire classification B-s2,d0 and a thermal conductivity of λ = 0.022 W/mK. Roof panels were installed in the same thickness using concealed fastening to the steel purlins, ensuring thermal continuity across the entire envelope — from plinth to ridge.
End result
The layered PIR composite delivered high thermal insulation at minimal wall thickness, translating directly into lower heating and ventilation costs for the broiler house. Rapid prefabricated assembly shortened the construction schedule, while the smooth steel facings simplify sanitary regime compliance inside the farm.
