Sandwich elements consist of multilayer panels with an insulation core – usually mineral wool – between steel or aluminium facings. The modularity of sandwich structures allows for versatile use as well as quick and economically priced construction. As a result, sandwich panels are especially used in the construction of industrial and production halls. However, special fire protection requirements are placed on the penetration sealing systems used as their reaction to fire differs from plasterboard walls and solid walls.
Many of our soft penetration seal systems have been successfully tested for a fire resistance duration of up to 120 minutes for use in sandwich elements.
