RS -2049 8-04 New) bi-fr PermaPly® 28 Johns Manville I � Description Johns Manville (JM) PermaPly 28 is a lightweight, asphalt- coated, fiber glass base felt. 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 base felts, as the fiber glass (inorganic) mat reinforcement is rot resistant and has low moisture absorption. �y ` r`WTiiu!Y�°' Use 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 -041 L AT GIasPIy® IV Johns Manville 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 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. Use GIasPly I'1 ph, 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 installed over nailable decks, a fiber glass base sheet, such as JM PermaPly® 28, is typically used as the first ply and is usually `�_. '' �- 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 `� -, y 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. "Brooming -in" • Controlled porosity allows the product to readily accept hot is not necessary, but use of a squeegee on GlasPly IV after laying it asphalt and disperse it throughout the entire felt, to stabilize the in hot asphalt will help ensure full contact is made with the asphalt. asphalt after cooling. • Readily accommodates gassing by venting volatile materials and moisture during application. • Low moisture absorption, excellent dimensional stability and resistance to rot makes it an ideal replacement for organic felt. • Easy to handle, lays flat, minimizes workmanship related problems. • Flexibility and conformability minimizes fishmouths, wrinkling and ridging.

RS -2073 12 -08 (Replaces 8 -04) bl GlasKap® Johns Manville Description GlasKap is a mineral surfaced, asphalt coated, fiber glass cap - sheet for use in hot applied built -up roofing systems. It is com- posed of a fiber glass mat with a high - quality coating asphalt and a white ceramic - coated granule surfacing on the side to be exposed to the weather. Use GlasKap is used as the uppermost finish ply in a variety of GlasKap built -up roofing systems. The ceramic - coated granule surfaced • sheet provides protection to the underlying asphalt and mem- brane, as well as the benefit of a reflective surface when white granules are used When installing GlasKap, it is important that the mopping asphalt be at the appropriate temperature: 20 °F ( -7 °C) above the asphalt's EVT is recommended. Advantages • Low moisture absorption, excellent dimensional stability and resistance to rot make it an ideal replacement for organic cap sheets. • Low maintenance compared to roofs that use coatings. • Should the roof be damaged, repairs are easy to make. Typical Physical Properties GlasKap is classified by Underwriters Laboratories Inc. as a Material meets the requirements of ASTM D 3909. Type G -3 Coated Cap Sheet.
