Product Description

75mm Cold storage room PIR/PUR wall insulated sandwich panels

1.PU foam wall panels type:

☆ Tongue and groove joint wall panels:


Panel effective width: 920/1000/1120 mm
Thickness: 75/ 100/ 150/ 200/ 250 mm
This panel type ensure the joint tightness,and the insulation performance of cold room.

2.Sandwich panel wall applications:


This PU wall sandwich panel is mainly used in refrigeration or refrigeration equipment in food and other industries, such as refrigerators, freezers, cold storage, refrigerated trucks, etc. Polyurethane rigid foam is the most ideal thermal insulation material for refrigeration and refrigeration equipment.

3.Wall panels material description:

Insulation core material :	PUR (Polyurethane), PIR (Polyisocyanurate)
Thermal Conductivity :	λPUR = 0.023 W/mK1 & λPIR =0.021 W/mK1
Density :	38 ~ 42 KG/M³
Steel sheet thickness :	0.40 ~ 0.75 mm
Stainless steel sheet thickness :	0.40 ~ 0.70 mm
Al-Mg-Mn alloy metal thickness :	0.70 ~1.20 mm

4.Sandwich panel roof features:

√ Tongue and groove joint structure improves the panel insulation and air tightness;
√ Stable panel structure;
√ Excellent waterproof performance;
√ Light weight,elegant appearance;
√Effectively solve the temperature difference in the refrigeration industry.

5.Metal panel basic technical property:
 

Compressive strength at 10% deformation (kg/cm²)	2.1
Bending strength (kg/cm²)	4
Tensile strength (kg/cm²)	3.7
Adhesive strenth (kg/cm²)- foam to steel	2.9
Water absorption (Volume %)	0.2% at 100%RH
Closed cell content (%)	92 ~ 95%
Vapor permeability at 90% (RH) & 38ºC (Gms/Hr.m²)	0.12
Fireproof level	PIR: B1; PUR: B2

6.Insulated wall panel packing & loading:
☆ Packing:
→ Sandwich panels will be sealed with PVC film to protect the surface steel sheets from damage;
→ Using our PU sandwich panels packing machine,and packing with nylon to make panels in suitable quantity and bundles;

→ After finishing the packing,we will stack them in neat and dry place,also will put sleeper or foam as support,to avoid any water on the groud to break the panels.


☆ Loading:
→ The delivery time for Yumi steel sandwich panels is depending on seasons and thickness of panels;
→ Each delivery is depending on where to deliver,if it's for domestic market,it will be transported by truck.If it's for foreign market,panels will be loaded in containers and delivered;
→ Loading and carrying surfaces in trucks or containers must be clean and dry. No nails or other sharp objects are allowed to be appeared in truck or containers. If any accessories,which is considering as protruding objects,then they have to be properly secured (should be packed with wooden blocks or waste foam), to avoid damage to the panels.
