Mold resistant AP/Sheet & Roll Insulation is a flexible elastomeric thermal insulation, black in color. It is furnished with a smooth skin on one side which forms the outer exposed insulation surface. The expanded closed-cell structure of makes it an efficient insulation. It is manufactured without the use of CFC’s, HCFC’s, or HFC’s. It is also formaldehyde-free, dust free, low VOCs, fiber free and resists mold and mildew. All AP products are made with Microban® antimicrobial product protection for added defense against mold on the insulation.
» AP/Sheet is supplied in flat sheets 36″ x 48″ (.915m x 1.22m), in nominal wall thicknesses of 1/8″, 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1-1/2″* and 2″* (3, 6, 10, 13, 19, 25, 38, 50mm).
» AP/Roll is supplied in 48″ wide (1.22m) continuous rolls in nominal wall thicknesses of 3/8″, 1/2″, 3/4″, 1″, 1-1/2″* and 2″* (10, 13, 19, 25, 38, 50mm). It is also available in 60″ (1.53m) in 1″ thickness.
NOTE: 1-1/2″ and 2″ available in 25/50 and non 25/50 rated.
AP is used to retard heat gain and control condensation drip from chilled water and refrigeration systems. It also efficiently reduces heat flow on hot systems.
Flexible AP/Sheet and Roll Insulation is used for all applications that cannot be accomplished by AP/Pipe Insulation. It is particularly adaptable for insulating:
For use on cold pipes, AP/Pipe Insulation thicknesses have been calculated to control condensation on the insulation outer surface, as shown in the table of thickness recommendations.
- Ductwork, large piping and fittings
- Curved and irregular surfaces
- All types of fitting covers
The recommended temperature usage range for AP/Sheet is -297°F to +220°F (-183°C to +105°C) according to method of application. With full adhesive coverage attachment, the surface to which it is applied may operate to a limit of 180°F (82°C). When used for pipe insulation with adhesive adhering seams and joints only, AP / Sheet can be applied to lines that will operate to a limit of 220°F (105°C).
For use on cold systems, AP/thicknesses have been calculated to control condensation on the insulation outer surface, as shown in the table of thickness recommendations.
AP/Sheet and Roll Insulation is acceptable in thicknesses through 2″ for use in air plenums. Conforms to NFPA 90A and NFPA 90B requirements. AP/Sheet and Roll Insulation meets the energy code requirements of International Energy Conservation Code (EICC) and ASHRAE for R-Value 4.2 at 1″ wall thickness and R-Value 8 at 2″ wall thickness.
Resistance to Moisture Vapor Flow
The closed-cell structure of AP prevents moisture from wicking and makes it an efficient insulation. For many applications, needs no supplementary protection.
Additional vapor-retarder protection may be necessary for when installed on very-low-temperature surfaces or piping or where exposed to continually high humidity conditions.
