Three-layer sandwich panels consist of two metal sheets, in-between which there is a layer of insulating material. Different materials act as insulators: mineral wool, ordinary fiberglass, polystyrene foam or polyurethane foam.
Metal insulated panels with mineral wool core filler are extremely easy to install. They can be quickly assembled (dismantled) under any conditions. Their advantages are heat resistance and a high degree of heat and sound insulation.
The panels are attached to the property with concealed fasteners. This roof system requires very little field reworking and can be easily and quickly installed.
The exterior surface of the metal sheets is protected by different alloys or compositions. Most often metal sandwich panels are coated with zinc. The thicker layer, the higher is the durability of the material.
