Product Description
Structural PU insulated sandwich panels for cold rooms

Product Description
The cold room panel, made of polyurethane, covered by SII, PVC coloured steel plate and stainless steel plate, can decrease the heat transfer effect generated by the temperature difference and help to reach the most efficiency for freezing and cold systems. Since the scientific, simple design and practical installation, the insulation system is a new system with low installation cost.

1. Basic Structure
Panels are joined together by means of tongue and groove and locked together by camlock on each side of the panel to ensure air tight joints. 
* Cam-lock design fastener to install cold room tightly and strongly
* Silica gel are used on the panel edge of the joint parts of each sandwich panel to ensure perfect sealing to avoid the cooling air leakage from the cool room or moisture inside the PU insulated panel for the best refrigeration and frozen storage result
2. Core Material
* Polyurethane (PU) density 40kg/m3 or above for perfect cold-room heat insulation efficiency 
*Fire retardant: B2 grade
3. Surface Material
Color painted steel, aluminum, stainless steel
4. Cold-room Panel Dimension
Standard width of the sandwich panels is 960mm.  Non-standard size PU insulation panels are also available upon request.
5. Various Panel Thickness 
Thickness from 50mm to 200mm of walk-in freezer & cooler panels is available, according to the room temperature to be maintained and outside design condition of ambient temperature.
