About this product
The FR Base Sheet is a tough non-asphaltic fiberglass-based underlayment. In conjunction with the Hot Mopped System, the FR Base Sheet can be incorporated to provide a suitable substrate for deck types requiring a fastened base. It is the ideal substrate for direct applications of the Hot Mopped System or Mechanically Fastened System over decks manufactured from wood, tectum, gypsum, and lightweight concrete.
