Now a days, the challenges caused by climate change are observable in the whole world.
Regardless of reconsidering about energy production, global efforts are largely focused on making energy consumption as efficient as possible. The buildings with poor insulation would waste energy the most, Therefore it would be more suitable to use material with high quality in construction application in order to save energy further to environmental protection.
As a result, It has been for so long that sandwich panels are being used in building facade insulation as an standard choice.
Sandwich panels have 3 layers with 2 external layers and rigid polyurethane foam with a very low heat transfer coefficient is used as mid layer and core of sandwich panel.
