Ice cream producer / food plant with cold storage — refrigerated hall | BOKKA
Cold storage hall for a food plant / ice cream producer — Rzeszów
The project involved the construction of a warehouse and cold storage hall for a food processing plant with frozen goods storage, located in Rzeszów (Subcarpathian region, southeastern Poland — within BOKKA’s regional sales coverage area). The facility serves as a low-temperature warehouse where finished frozen products are stored prior to distribution. Lightweight envelope technology based on sandwich panels enabled the thermal shell of the building to be closed quickly, preparing the space for refrigeration system installation.
Design challenge
A frozen storage warehouse for the food industry requires maintaining stable, low internal temperatures around the clock — which translates into demanding requirements for the external envelope. Critical factors included minimal heat loss (target U-value below 0.20 W/m²K for the cold zone), airtightness of panel joints, and resistance of the insulating core to temperature fluctuations. A short envelope installation time was also an essential criterion, allowing the refrigeration and production lines to be commissioned without delay.
Solution applied
The project used insPIRe® sandwich panels with a PIR (polyurethane) core — a solution dedicated to refrigerated and frozen storage facilities, where every fraction of the λD coefficient counts. PIR sandwich panels deliver significantly higher thermal insulation efficiency than classic mineral wool solutions at comparable thickness, allowing the usable cubic volume of the hall to be optimised without compromising on insulation performance. Panels were installed using the standard hidden-fastener method on a steel structural frame, with reaction-to-fire class B-s2,d0 in accordance with EN 13501-1.
Final outcome
The insPIRe® sandwich panel envelope delivered the high thermal insulation parameters required for an industrial freezer facility and full air-tightness of the building partitions. The technology shortened envelope construction time compared with traditional methods and prepared the facility for many years of operation under low-temperature regimes — in line with food industry standards (HACCP, BRC).
