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
