Rockwool sandwich panels occupy the market widely because of their advantages of fire resistance, good sound insulation and strong insulation performance. More and more companies choose to sell rock wool sandwich panels, construction sites, and more and more rock wool sandwich panels in the factory. So how do you choose high-quality rock wool sandwich panels?
The rock wool sandwich panel has a good sealing effect, and the sandwich panel is generally produced by an assembly line, which is similar in appearance of the overall product. The sides of the sandwich panel are sealed with polyurethane, and the polyurethane effect is relatively good. It can well overcome the rock wool’s moisture return due to easy water absorption, which can greatly improve the service life of the rock wool sandwich panel. Therefore, when selecting the sandwich panel, it is necessary to use a polyurethane rock wool sandwich panel.
The rigidity of the sandwich panel is very important. If it is too soft, the sandwich panel is easily bent and deformed, resulting in collapse and the like. Polyurethane seals the rock wool core layer and makes polyurethane and rock wool a whole. Moreover, the outside of the sandwich panel is wave-pressed, which is much stronger than the conventional composite profiled rockwool. When the rock wool sandwich panel is firmly fixed by the stringer, the rigidity of the layout can be better improved.
