Installation Peocedures

KIMMCO Stonewool LRB Mattresses are pre-cut in required dimensions and wrapped around the surface to be insulated. The joints are laced with galvanized wire by passing it through the eyes of the wire mesh. Care should be taken to ensure that the joints fit properly and no gaps are left at the joints. During the application on large surfaces, the mattresses should be impaled over 5-6 welded pins per square metre. The mattresses are held in position by placing retaining washers over the pins. These pins also work as spacers for the insulation between the sheet metal cover and the insulated surface.
