Maintaining the cold chain in the food industry is critically important for both product quality and legal compliance. In Turkey, insulation performance, hygiene standards and energy efficiency must be evaluated together within the framework of TS EN 13964 and EU Cold Chain Regulations for food warehouses. Incorrect panel selection can increase annual energy costs by up to 30%, while faulty door systems can lead to cold air leakage and HACCP violations. In this guide, we cover the essential technical parameters and correct system selection step by step for cold storage installation.
How to Determine Cold Storage Sandwich Panel Thickness?
Cold storage sandwich panel thickness varies directly according to the target temperature range of the warehouse. According to general industry practice:
PIR-filled sandwich panels offer approximately 20–25% lower thermal conductivity at the same thickness compared to EPS (expanded polystyrene) fillings (λ ≈ 0.022 W/mK). This difference directly affects long-term energy savings.
As Bosan Industrial Building, the cold storage sandwich panels we offer are presented to our customers in detail along with thermal analysis and project calculations before site work begins.
Critical Technical Parameters in Food Warehouse Cold Room Design
In a food warehouse cold room design, not only panel thickness but also floor insulation, moisture barriers and corner joint details play a decisive role. Especially for food preservation, the following criteria come to the fore in TSE and Ministry of Agriculture inspections.
In addition, thermal bridge calculations within the scope of TS EN ISO 10211 standard must be done at the project stage for both energy efficiency and condensation control.
What to Consider When Choosing a Cold Storage Door?
Cold storage door selection is a critical decision that directly affects the entire system performance. In the food sector, door systems differ according to transition frequency, vehicle traffic and hygiene requirements.
Sectional Doors: Preferred in warehouses with high-frequency forklift and vehicle passage, sectional doors efficiently use ceiling space thanks to their horizontal opening. They limit heat loss with a minimum 42 mm PUR-filled panel structure. The sectional door systems offered by Bosan are equipped with motors and control units suitable for industrial frequency use.
Cold Storage Hinged and Sliding Doors: These doors, used in low-traffic compartments requiring manual access, should be manufactured with 80–120 mm insulation thickness; there should be a heated gasket system on the door frame. The heated gasket eliminates the freezing problem in applications below -18°C.
Fast Doors (High-Speed Curtain Doors): Fast doors that minimize cold losses in heavy traffic open at 0.5–1.5 m/s with PVC or fiberglass curtains; their contribution to energy efficiency has been measured as 18–22% cold savings in tests (Frigo-Trans Industry Report, 2023).
Calculations on Energy Efficiency and Operating Costs
The impact of correct panel and door system selection on investment return should not be overlooked. In comparative analyses conducted in a 500 m² cold storage:
| Panel Thickness | U-Value (W/m²K) | Annual Energy Savings |
|—|—|—|
| 80 mm PIR | 0.28 | Baseline |
| 120 mm PIR | 0.19 | 22% savings |
| 150 mm PIR | 0.15 | 31% savings |
| 200 mm PIR | 0.11 | 42% savings |

In light of this data, especially for deep-freeze facilities, it is observed that the initial investment is recovered as energy savings within 3–5 years.
The Importance of Turnkey Solutions in the Installation Process
Fragmented supply models in cold storage projects can cause assembly errors, warranty gaps and coordination losses. Bosan Industrial Building’s turnkey project model manages the entire process from design stage to site assembly completion under one roof.
Within the scope of this model; thermal calculation, panel supply, door system installation, integration with cooling infrastructure and final control inspections are carried out in a coordinated manner by our expert team. The field experience gained in projects carried out throughout Turkey, especially in Kocaeli, Istanbul and Ankara, is directly transferred to each new project.
FAQ: Frequently Asked Questions About Cold Storage Installation
What should the minimum panel thickness be for cold storage?
While it varies according to target temperature, a minimum of 80 mm for cold rooms between +2°C and +8°C, and a minimum of 150 mm PIR-filled sandwich panel for -18°C deep freeze warehouses are accepted as industry standards. The U-value should be kept below 0.20 W/m²K.
Why is the heated gasket important in cold storage doors?
In applications below -18°C, condensation and ice formation on the door frame are inevitable. The heated gasket system prevents this ice buildup, ensures the door closes tightly and reduces mechanical failures. It is also a critical element for HACCP compliance in food warehouses.
What is the difference between sectional doors and fast curtain doors?
Sectional doors are suitable for heavy vehicle traffic with their durable structure and high insulation value. Fast curtain doors are preferred to minimize cold loss in high transition frequency. The ideal installation uses both systems together in loading areas.
How should the floor of a food warehouse cold room be designed?
In food warehouses, the floor should be designed with anti-bacterial surface coating, minimum 150 mm thermal insulation and moisture barrier. If there is forklift traffic, reinforced floor panels with a load-bearing capacity of at least 5 kN/m² should be used.
What standards apply in cold storage installation?
In Turkey, TS EN 13964 (cold storage panels), TS EN 1627 (door security) and Ministry of Agriculture Food Hygiene Regulations are the basis. For projects aimed at the EU market, CE marking and EHEDG hygiene design criteria are additionally applied.
Conclusion: Right Choice, Long-Term Savings
In cold storage investment, panel thickness and door system selection directly determine both operational efficiency and legal compliance. Wrong choices come back as irrecoverable energy losses and maintenance costs in the first year. As Bosan Industrial Building, we analyze the technical requirements of your project in detail before going to the field; we offer the correct panel thickness, door system and assembly planning with turnkey solutions.
