The method of fixing the rock wool sandwich panel is firm and reasonable, and it is common practice to use the purlin and the screw on both sides of the polyurethane. This special purlin and screw can fix the sandwich panel well and can withstand earthquakes below 8 and typhoons below 10.
The surface of the rock wool sandwich panel must be protected against scratches to prevent the polyurethane on both sides from being scratched. Rainwater and air enter the sandwich panel. The sheet is easily damaged after a long time. Therefore, a polyethylene self-adhesive protective film is adhered, which can prevent the sheet from being scratched during transportation and handling.
Rockwool sandwich panels should also pay attention to aesthetics. The interface is generally designed and produced by European standards. The board surface is more flat, the joints are more rigid, and the strength is reliable to prevent the sheet from rupturing due to thermal expansion and contraction.
Materials, production processes, accessories, etc. are all issues that should be noted when selecting rock wool sandwich panels.
