1. Lightness of walls made of sandwich panels compared to other materials
2. Speed of transportation and ease of installation and execution of sandwich panels at height
3. High resistance against shearing forces caused by Earthquake
4. Insulation against heat, cold, moisture and sound
5. Resistance to fire due to the presence of concrete layers around the panels
6. Impenetrability of the building against insects
7. Possibility Carrying and using 3D panel in hard-to-reach areas to build a building without the need for specialist personnel
8. Achieving more useful space due to low thickness
9. Freedom of action in implementing various designs due to flexibility 3D panel prefabricated parts
10. Saving the cost of foundation and skeleton of high-rise buildings, ten reasons for the low weight of the roof and wall panels
11. Saving the cost of building air conditioning in summer or winter due to preventing the exchange of heat or cold as a result of spending less energy
12. Increasing the useful life of the building and its installation devices
13. The relative absence of noise pollution and creating peace for the residents of the building in big cities
14. The return of investment in construction matters in the shortest time
15. Passing water and sewage pipes, electricity and telephone simply from below 3D panel networks and installation of door frames and metal shutters of windows before pouring concrete and generally implementing building facilities with the lowest cost
16. No need to carve and destroy the walls and roof facilities and as a result no creation Accumulated trash that saves money and time. 17. After spraying concrete on the sides of the panels or a thickness of at least 3 centimeters, the panels do not need plaster mortar and soil, and by applying plaster (whitewashing), the walls and the roof will be ready for painting.
18. Removal of the door sole in the advanced sandwich panel system
19. The transportation of the panels is done at a low cost, and for example, a trailer can carry more than 1000 square meters of panels. Carry the single-wall type
20. The use of walls and roofs in the construction of panels makes for a suitable efficiency of the consumed iron. For example, by spending 17 kg per square meter of steel in the form of wire and rebar, one unit can be made. He built a one-story residential building
