Cold room door panels maintain consistent internal temperatures from -40°C to +10°C in walk-in refrigerators and freezers. The panels combine a rigid Polyurethane (PUR) or Polyisocyanurate (PIR) foam core with metal cladding layers of stainless steel or galvanized steel. Foam density ranges from 40 to 50 kg/m³, providing compressive strength and moisture resistance while meeting European Commission/United States Department of Agriculture (EC/USDA) hygiene requirements.
Construction features tongue-and-groove interlocking edges with internal cam-lock fasteners that create airtight joints. The cam-lock mechanism enables quick installation using only an Allen wrench, eliminating thermal bridging and minimizing air leakage. Common thicknesses include 100mm and 150mm, with standard widths of 960mm, 1000mm, or 1120mm.
Thermal conductivity values range between 0.020 and 0.024 W/mK, delivering R-values from R-5 to R-8.8 per inch. The closed-cell foam structure resists moisture ingress and inhibits fungal growth, maintaining hygiene standards with B1 or B2 fire resistance ratings.
Applications include food storage, pharmaceutical facilities, distribution warehouses, and healthcare environments requiring precise temperature control. Customization options encompass RAL color charts, surface finishes, specialized handles, viewing windows, and emergency escape devices for enhanced functionality.

Frequently Asked Questions
What materials are used in RaxPanel cold room door panels?
RaxPanel cold room door panels are made with CFC-free insulated PU panel covered with stainless steel or galvanized steel that meet EC/USDA international hygiene standards. The door leaf is typically made of galvanized steel sheet or stainless steel for food-safe applications, with a protective and decorative coating.
What thickness options are available for the door panels?
Common thicknesses for cold room door panels are 100mm or 150mm, but options include 80mm, 100mm, 120mm, and 150mm to suit various insulation needs and applications.
How are the door panels installed and sealed?
The door panels are seamlessly joined together by means of tongue and groove and locked with cam-lock fasteners on each side to ensure airtight joints. This design allows for tight and strong installation, preventing air leakage.
What are the thermal insulation properties of the door panels?
The door filler is rigid PUR polyurethane foam with a density of up to 50 kg/m³ and a thermal conductivity coefficient of 0.022 W/(m*K), providing excellent thermal insulation to effectively keep warm or cold air contained.
Can the door panels be customized to specific sizes?
Yes, cold room door panels are available in customized sizes and structures. Common sizes include 700mm*1700mm, 800mm*1800mm, and 1000mm*2000mm, with options for half buried or all buried installation depending on the cold room scenario.
What applications are suitable for these door panels?
These door panels are widely used for walk-in cold rooms, blast freezer rooms, clean rooms, greenhouses, and planting rooms. They are ideal for maintaining consistent temperatures in food storage, pharmaceuticals, and other perishable goods applications.
What safety features are included with the door panels?
The door panels include a safe escape device for emergencies, allowing entry from inside when locked. They also feature fire resistance, reliable structure, and high-quality hardware parts for enhanced safety and durability.
