Freezer Room Panels

Freezer room panel is a cold storage insulated panel that offers a superior thermal performance for a wide range of climate-controlled environments such as refrigeration & freezing applications, modular cold rooms, walk-in freezer rooms, walk-in fridges, freezers & chiller units. A freezer room panel is an insulated sandwich panel consisting of a thermally resistant insulation rigid core sandwiched between two layers of metal sheets, the insulation core is usually made from PUR (Polyurethane), PIR (Polyisocyanurate), EPS (Expanded Polystyrene Foam) and XPS (Extruded Polystyrene Foam), while the two skin-layer comes in high strength material such as Galvanized steel sheets, Aluminium steel sheets and Stainless steel sheets.

Freezer room panel is also referred to as blast freezer panel, shock freezer panel or cold storage panel.

Freezer room panels are made of three layers: a low-density insulating core and two layers of metal sheets bonded to each side, these components are available in different materials such as:  

External Layers

The shielding layers are often made from metal sheets like Pre-painted galvanized steel (PPGI), Aluminium sheet, Stainless steel sheet, or Glass Fibre Reinforced Plastic (GRP). 

Insulation Core

Freezer room panel is usually made from the following insulating core:

PU, PUR (Polyurethane)

PIR (Polyisocyanurate) 

EPS (Expanded polystyrene foam) 

XPS (Extruded polystyrene foam)

Freezer room panels are popular for walls, floors, ceilings and roofs, these highly versatile cold storage panels are particularly suitable for businesses that deal with perishable goods and temperature-sensitive products such as:

Industrial Freezing

Industrial Cold Storage

Cold Storage Warehouses 

Refrigeration Warehouse 

Food Processing Facilities

Meat Processing Plants

Seafood Processing Facilities

Frozen Vegetables & Fruits Plants

Frozen food Processing and Packaging Plants

Restaurants and Bakeries

Hotels & Catering Units

Hypermarkets and Convenience Stores

Pharmaceutical & Medical Products

Cold Chain Logistics Trailers

Refrigerator Truck or Chiller Lorry

Freezer room panels are designed to offer high technical performance and maximum thermal insulation, these insulating panels are mainly designed to maintain the required temperature and ensure products are safely stored and protected from external factors that may affect the quality of temperature-sensitive products. Also, due to thermal resistance and airtight design, freezer room panels’ offer increased energy efficiency which saves energy and money, while also ensuring high freezing performance in different environmental conditions.

Freezer room panels are thermally resistant panels that help maintain a negative temperature that ranges from -40C° to -10C°, thanks to the excellent thermal conductivity and closed-cell insulation which ensure products are kept fresh at low temperatures and fast freezing speed.

Freezer room panels are designed to offer superior thermal performance for a wide range of freezing and refrigeration applications, the R-value describe the thermal efficiency of a freezer room panel and depends entirely on the insulating core type, properties, and thickness, the most commonly used insulation are as follow:

PUR typically provide an R-value of 5-7.1 per inch 

PIR R-value range normally from 7-8.0 per inch 

EPS cores offer an R-value of R-4 to R-5 per inch

However, materials with high R-values provide better insulation, while the freezer room panel R-value should be not less than 40, it is also important to select an insulating core with a thickness that ranges between 5 and 30 cm, whilst, airtight sealing is required to prevent air/water leakage and prevent harmful bacteria.

A wide range of protective coating can be applied to the outer layer of a freezer room panel to protect the complete surface from environmental factors such as corrosion, UV radiation, and moisture, highly durable protective coating can be used including Polyester, PVDF and Plastisol, also, the freezer room panel interior and exterior surface can be finished with standard polyester with 15 μ or 25 μ thickness, double paint coating or food grade coating.

Freezer room panels are excellent for freezer room envelopes, given the high structural rigidity, excellent insulation properties, durable metal sheets, high strength-to-weight ratio and air tightness; these sandwich-structural composites can last for decades and require minimal maintenance. Moreover, the structural functionality of a freezer room panel is similar to the classic I-beam, where the two facing sheets are similar to the I-beam flanges which resist primarily the in-plane and lateral bending loads, while the core material acts as the web of an I-beam which withstand the shear loads.

Freezer room panels are the perfect solution for the food and beverage industry, thanks to the food-grade material which provides full protection against external factors such as bacteria, moisture and corrosion, while the insulating material is CFC & HCFC-free, while each unit is designed and manufactured to deliver bespoke specifications required for EU GMP “Good Manufacturing Practice”, USDA standards, and ISO standards for cold storage applications.
