The aesthetic and functional appeal of a building is improved by rock wool colored sandwich panels. The outer layers blunt the technical appearance of the bouldings which makes them more attractive. They offer customization possibilities since they come in different colors. The color coated surface is also processed to be resistant to harsh weather, protecting the rock wool core. These panels can be used for commercial and industrial buildings as they suit a particular style, while their insulation and fire resistance capabilities make them rock wool panels.
