Rockwool sandwich panel surface must have anti-scratch protection.

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.
