Introduction For Insulated Sandwich Panels

Feb 06, 2017

Brief introduction:

sandwich panel is a structure made of three layers: low density core inserted in between two relatively thin skin layers. This sandwich setup allows to achieve excellent mechanical performance at minimal weight. The very high rigidity of a sandwich panel is achieved thanks to interaction of its components under flexural load applied to the panel: core takes the shear loads and creates a distance between the skins which take the in-plane stresses, one skin in tension, the other in compression. General information on sandwich panel structure, different sandwich core types available and the potential with respect to weight savings is available in the following reference.


Sandwich panels types:

According to different kinds of core material:

EPS sandwich panels(at current market,this panel is widely used);

XPS sandwich panels;

PU sandwich panels(polyurethane sandwich panels);

PIR sandwich panels;

PF sandwich panels;

Rock wool sandwich panels;

Form metal sandwich panels.


According to different kinds of skin plate:

Metal sandwich panels;

Non metal sandwich panels.


The feature of Sandwich panels:


1)Heat & Fire Insulation;  

2)Inflaming Retarding;

3)Easy installation;

4)Excellent price and quality;

5)Light weight.
