Cover Board External Corner White
Cover Board External Corner 304mm (H) x 55mm (D) x 55mm (W) are used to cover the expansion gap that should be left at the junction of two cover boards at the corner of the roof. As with all joints and corners, one side should be glued and one side sealed with silicon sealant. This trim should be cut to size with either a fine toothed saw or hacksaw.
