Carlisle's G2 Base Sheet is a non-porous 28-pound base sheet uniquely designed and constructed to be strong while remaining wrinkle resistant. The asphalt coating helps maintain a uniform consistency on both sides of the sheet and eliminates pinholes. The unique combination of strength and suppleness is achieved by coating the heavyweight, specially designed fiberglass mat with type IV asphalt. The suppleness and extreme pliability of the G2 Base Sheet make it a good alternative for organic base where a decay resistant inorganic mat is desired. G2 Base Sheet is used as a base ply in a wide variety of cold- and hot-applied asphalt applications with Carlisle's AFX cap sheets.
