☆ Types of sandwich panels

Sandwich panels are one kind of thermal material for roof and wall,which are made from two thin metal sheets and one thick core material.According to different kinds of core material,there are EPS,PIR/PUR,Rockwool,glass wool,hollow glass magnesium sandwich panels,etc. Hereby,we will introduce the types that people often heard.

EPS sandwich panels:

Effective width:950/1150mm

Panel thickness:25/50/75/100/150/200/250mm

Length:Customized

Surface sheets:PPGI/ PPGL/ Aluminum sheets/ Al-Mg-Mn alloy metal sheets/ Stainless steel

EPS density:8-20 KG/M³

U value:0.86~0.16 W/m² K

Fire resistance:A2

Main feature:Light weight;Competitive price;Easy installation

PIR/PUR sandwich panels:

Effective width:930/1000/1120 mm

Panel thickness:30/40/45/50/60/75/100/150/200/250mm

Length:Customized

Surface sheets:PPGI/ PPGL/ Aluminum sheets/ Al-Mg-Mn alloy metal sheets/ Stainless steel

PUR/PIR density:40-42 KG/M³

U value:0.57~0.11 W/m² K

Fire resistance:PIR:B1 ; PUR:B2

Main feature:Best insulation material;High panel strength;Excellent waterproof performance; Easy installation

PIR/PUR sandwich panels are the best insulation material in the world now.According to different application,you can choose different joint of PU sandwich panels.For example,if you want to build a cold room,we will advise you to use tongue and groove joint cold room panels.So you can advise us which kind of building you will build and our team can offer you related professional advice.

Effective width:950/1150/1000/1120 mm

Panel thickness:50/60/75/100/150/200mm

Length:Customized

Surface sheets:PPGI/ PPGL/ Aluminum sheets/ Al-Mg-Mn alloy metal sheets/ Stainless steel

Rock wool density:80-150 KG/M³

U value:0.64~0.20 W/m² K

Fire resistance:A1

Main feature:Best fireproof material; Excellent soundproof performance

There are pure rockwool sandwich panels and PU sealing rockwool sandwich panels. The main difference is the PU sealing end,with it,the rockwool insulate panel strength and waterproof panels will be much more better than pure rockwool metal panels.

Glass wool sandwich panels:

Effective width:950/1150/1000/1120 mm

Panel thickness:50/60/75/100/150/200mm

Length:Customized

Surface sheets:PPGI/ PPGL/ Aluminum sheets/ Al-Mg-Mn alloy metal sheets/ Stainless steel

Glass wool density:48-64 KG/M³

U value:0.79~0.20 W/m² K

Fire resistance:A1

Main feature:Fireproof material; Soundproof performance

☆ Difference between different kinds of sandwich panels:

(which type of sandwich panels is suitable for your project?)

To understand about the difference is a way to help you choose the correct types of sandwich panels roof or wall for your project.The tip is to understand the main feature of each kind of sandwich panels.

EPS sandwich panels:The budget option,lightweight,most suitable for temporary buildings and mobile homes;

PIR/PUR sandwich panels:The best thermal material,high strength,most suitable for cold area,cold storage project;

Rockwool sandwich panels:The excellent part is fireproof and soundproof.

Glass wool sandwich panels:The main feature is high level fireproof performance.

☆ What are sandwich panels used for?

Here we list a chart for you to understand the application of each type of sandwich panels.

☆ Why use sandwich panels?

Here we reveal advantages of sandwich panels in three key areas:

★ Straightforward cost

There is not very complicated installation process on sandwich panels roof or wall,so you can get an exact cost for both material and labour cost easily.

★ Construction time

Compare to single skin metal panels or traditional roofs and walls,the construction time of using sandwich panels is far more quickly.Another plus is that there is no need to wait for the building shell to lose excess moisture.

★ Construction process

During sandwich panels construction process, there is not‘wet processes’,or fixed and controlled relative humidity levels required.

For more reasons to choose sandwich panels,you can also refer to “4 reasons to choose sandwich panels”,then you can understand more better.

☆ How much does sandwich panel cost?

The cost of sandwich panels is various based on panel specifications,colors and thermal insulating core material.The budget choice is EPS sandwich panels,if considering long term performance and cost effectiveness, PIR/PUR sandwich panels is the best choices.Here we will offer you one rough price range of different sandwich panels:

☆ How to install sandwich panels?

Hereby,we briefly introduce the installation steps of sandwich panels roof and wall:

★When sandwich panels and related accessories(including flashing, fasteners, gaskets, seals, etc.) are delivered to the site,the construction team or house owner needs to check each details with material list;

★ Unloaded sandwich panels properly with construction handling equipment;

★The subframes are well assembled, and then installed with beams, posts and purlins;

★ Removed the protective film from sandwich panels;

★Using suitable fasteners and fasten sandwich panels to the subframe structural members;

★The joints between the sandwich panels are sealed and the flashing need to be installed properly.
