What Insulation Materials Are Best for Cold Room Sandwich Panels?

 

Cold room sandwich panels are available in different insulation materials including PUR and PIR which have been used for decades and becoming more and more popular for cold rooms:

Polyurethane (PU/PUR)

Polyurethane insulation is a sealed cellular insulating material that is produced by reacting a polyol with diisocyanates, this type of material provides high density and excellent thermal conductivity coefficient, λ = 0.022, while it ensures high resistance against moisture and fire, besides, polyurethane insulation core create an air-tight barrier against water, vapor and humidity, which provide high insulation performance and increase energy-efficiency, thanks to the closed cell structure and high cross-linking density of PUR which guarantee heat stability, and reduce energy requirements for large commercial and industrial cold rooms and refrigeration and freezing systems.

Polyisocyanurate (PIR)

Polyisocyanurate (PIR) is a thermoset plastic typically created by adding a blowing agent to a mix of polyols and isocyanates, produced as rigid thermal insulation, the PIR foam insulation is made of closed-cell, this offers superior thermal resistance for industrial and commercial cold room applications in addition to an excellent fire resistance performance, however, when compared to PUR (Polyurethane), PIR (polyisocyanurate) has a higher R-value, which provide better thermal insulation, and allow high energy efficiency in buildings. Hence, PIR cold room sandwich panels are more suitable for environments exposed to humidity and moisture. Polyisocyanurate (PIR) is also referred to as polyiso, or ISO.

What Are The Benefits Of Cold Room Sandwich Panels?

Cold room sandwich panels offer numerous benefits for both commercial and industrial cold rooms, due to their unique design and durable material, cold room sandwich panels offer unmatched benefits across a wide range of applications:

Thermal Resistance

Cold room sandwich panels offer high thermal conductivity (λ-values/K-value) ranging from 0.024 W/(m·K) for polyurethane and 0.05 W/(m·K) for mineral wool, whereas, their R-values vary depending on the type of insulation core, properties, density (>42kg/m³) and thickness.

These thermally-resistant sandwich panels are designed to provide high thermal performance and air tightness to cold rooms, this maintains optimal indoor temperature, prevents air leaks, and minimizes heat transfer through the cold room, these characteristics make them the first choice for applications with temperature control and energy efficiency requirements, such as industrial cold rooms, commercial cold rooms, cold storage facilities, etc.

Strength

Cold room sandwich panels offer an exceptional strength-to-weight ratio to large cold room structures, thanks to their rigid skin layers, and lightweight insulating core material which allows them to withstand substantial loads and maintain the structural stability of cold rooms. Also, when compared to traditional construction materials, cold room sandwich panels are incredibly lightweight and strong, this lightness and strength make it widespread for construction applications such as walls, partitions, roofs, ceilings and floors. The structural functionality of a cold room sandwich panel is similar to a classic I-beam, where two thin skin layers are designed to resist the in-plane and lateral bending loads, whereas, the insulating core material can resist shear loads.

Cost-Effective

Cold room sandwich panels are a cost-effective building envelope, each unit is designed to maintain a controlled environment, and offer a high insulation performance at an affordable cost. Also, this energy-efficient composite insulated panel can reduce significantly energy consumption, and thereby ensure better energy saving for the long term, however, when compared to traditional building materials, cold room sandwich panels are extremely durable and have a longer lifespan, also, cold room sandwich panels are more economical and offer exceptional performance, easy to install, and require minimal maintenance. Cold room sandwich panels can be also reused or replaced.

 

Environmental Sustainability

Besides, cold room sandwich panels are moisture-resistant, vermin-proof, rot-proof, and non-deteriorating.

These eco-friendly composites have become a vital component in green buildings as it doesn’t require repainting or maintenance like brick and concrete structures.

Are Cold Room Sandwich Panels Corrosion Resistance?

Cold room sandwich panels are corrosion-resistant structural panels, thanks to the corrosion-resistant inner and outer skin layers which protect the cold room surface from the impact of rust and deterioration, this makes them an excellent option for chemical processing plants, seafood processing rooms, coastal areas and working environment characterized by wet and high moisture.

Different types of metal surfaces can be provided to prevent corrosion caused by several factors such as aggressive corrosive environments, humidity areas, coastal areas, and salt. However, stainless steel sheets are preferred because it does not rust due to the formation of stainless steel sheet, however, the level of corrosion resistance depends mainly on the formation of “passive” chromium oxide film applied on the stainless steel surface, for example, oxide film, grades AINSI 304 stainless steel and 316 contain approximately 18% chromium, while they can be finished using double paint coating on galvanized steel sheet, and aluminum sheet.

Are Cold Room Sandwich Panels Fire Resistant?

Cold room sandwich panels offer the best performance in fire resistance, given their fire rating insulation core and high strength metal layers, cold room sandwich panels act as passive protection for a wide range of applications including internal and external walls,  interior partitions, facades, ceilings, roofs, and floors. The fire resistance of cold room sandwich panel varies between 30 and 240 minutes, whereas their fire behaviors and reaction to fire depend mainly on the insulation core, skin layers thickness, joint details, and the type of coating, also, flame retardants are normally added to combustible insulation to prevent burning and slow the spread of fire, while non-combustible insulation such as Rock wool insulation can withstand temperatures above 1,000°C in the case of fire, also when exposed to fire, this type of insulation does not burn or release toxic smoke.

 

Are Cold Room Sandwich Panels Hygienic?

Cold room sandwich panels offer the best hygienic environment for a wide range of industries including temperature-sensitive products, agri-food, seafood, meat-processing plants, food storage and logistics, pharmaceutical products, healthcare solutions, electronics, and other industries that require a constant temperature environment to keep their product protected, thanks to the superior thermal insulation which resist moisture, mold, mildew, and high humidity environment, while the most hygienic coating can be applied to the surface to prevent contamination, bacteria, germs and other factors that are harmful to health.
