Bakor Blueskin RF200 is an SBS modified bitumen membrane reinforcing with a blue polyethylene film. The membrane is specifically designed to be self-adhered on sloped roof surfaces. Bakor Blueskin RF 200 is used as a self-adhered membrane designed to be adhered directly to roof decks or certain insulation panels prior to the application of finished roof coverings, including architectural metal, shingles, cedar shakes, or tile. Its main function is to serve as a secondary waterproofing layer, in both residential and commercial building, protecting the buildings interior from damages caused by water infiltration as a result of ice dam formation and wind driven rain.
