It is manufactured by coating a JM wet process fiber glass mat with a weathering grade asphalt, and then surfaced with a fine mineral parting agent. - =�� PermaPly 28 is well suited as a replacement for coated organic 4 � � ' base felts, as the fiber glass (inorganic) mat reinforcement is rot resistant and has low moisture absorption. #amply wn. r ^v ry Use 4 PermaPly 28 is designed for use as the first or base ply in built -up and modified bitumen roof assemblies. It is ideal for applications where mechanical attachment of the membrane to the roof °� substrate or roof deck is desirable. PermaPly 28's asphalt coating makes it suitable for use as an intermediate or ply felt in cold � applied built -up and modified bitumen roof assemblies. ° Advantages • Easy to handle and lays fast. • Exceptional pliability. • Low moisture absorption, excellent dimensional stability and resistance to rot make it an ideal replacement for organic base sheets.

RS -2016 11 -08 (Replaces 8-04) 2 1 M GlasPly® IV Johns Manville I G Description = ; GlasPly IV is a specially constructed ply felt that is formed by $; coating a JM wet - process fiber glass mat with a light film of 3 asphalt which is then surfaced with a liquid parting agent that prevents the roll from sticking to itself, while providing a clean, easy -to -mop surface. Laying lines are applied on the top surface of the felt so it can be installed with the exposure needed to provide the correct number of plies required by the specification. P Y Use 14, asP,ly l r s GlasPly IV is intended for use as an integral part of any built -up or modified bitumen roofing system, over nailable and non- nailable roof decks and approved types of roof insulation. When �� x installed over nailable decks, a fiber glass base sheet, such as JM PermaPl 28, is typically used as the first ply and is usually Y� tYP Y P y y' � mechanically fastened to the deck. Subsequently, layers of GlasPly __ IV are set in hot asphalt to "build up" the applicable number of plies. Non - nailable decks and approved insulations usually have multiple a - r .� ... ' layers of GlasPly IV adhered directly to them with hot asphalt. Advantages GlasPly IV has good flexibility, conformability and superior strength • Consistent tensile strength and tear resistance. in both the machine and cross machine directions.
