Our sandwich panel roof and wall system is the perfect solution for your steel structure warehouse building project with its superior insulation and durability, it provides excellent protection against weather conditions.

As you know, there are various types of insulation materials, then which one is suitable to your project ?  If you need a better sound insulation and fire proof material, you can consider the rock wool sandwich panel, another popular insulation materials are polyurethane sandwich panel and polystyrene sandwich panel which have a good thermal resistance.

Before you choose a proper sandwich panel type for your project, you need to compare the thermal conductivity of each insulation panel, the lower the thermal conductivity is, the better heat insulation the material will be. For example, the thermal conductivity of eps panel is ≤0.041W/(m.K), and PU panel is ≤0.027W/(m.K), so PU panel is a better thermal insulation material. Of course, it has something to do with the thickness of the material also, standard thickness of sandwich panel is 50 mm, 75 mm and 100 mm.

R-Value is another important index to specify an insulation material’s thermal resistance performance, the higher the R-Value the better thermal resistance the material will provide.​

R-Value = Thickness (m) / Thermal conductivity (W/Mk)

 

From the above formula you will find there are two factors affecting the thermal resistance of the different sandwich panels, that is the thickness and the thermal conductivity of the insulation materials.

 

Take eps panel and PU panel for example again, that means you can use thicker eps panel to replace PU panel, to achieve a same thermal resistance, but with lower cost, because the price of PU panel is almost twice that of eps panel.

 

So based on the above calculation, you will also find, to get a specific thermal resistance, increased the sandwich panel thickness is more economically efficient then using a product with a lower thermal conductivity.

Above is a project we completed in Indonesia, for a 6,000 square meter of powder house, by sandwich panel with high thickness of metal sheet. 

 

We provided sandwich panel walls, sandwich panel roofs, all related sandwich panel accessories, hardware, downpipe etc.

If you have a warehouse to build, we can provide design and supply all materials for the steel structure building, or just sand sandwich panels wall and roofing system and related aluminum profiles. You can give us your required size and quantity of wall panel, roof panel, fittings for your steel structure warehouse, or you can send us the drawing of your warehouse, we will calculate and send you the proposal.
