- Product Summary
- Polyboard 180 Combo is an SBS polymer-modified polyester-reinforced base sheet factory-bonded to an asphaltic overlay board, manufactured with 4” lap extensions on one side and on one end. It is designed to provide a flame barrier over flame sensitive substrates for safer torch-welding of SBS cap sheets. The combination of membrane and asphaltic board makes application a one-step process. This product may be installed over wood, concrete, rigid insulation or as a recover sheet over an existing roof surface which is to be re-roofed. It is produced in sheets 36” wide by 60” long. It has a self-adhering 4” side lap and a self-adhering 4” end lap.
