DynaKap™ FR CR
DynaKap™ FR CR is a fire-resistant, elastomeric modified bitumen cool roof cap sheet incorporating the features of a strong composite fiber glass/polyester mat. The composite reinforcement is coated with a blend of SBS (Styrene-Butadiene-Styrene) rubber, high-quality asphalt and fire-retardant additives. The elastomeric asphalt blend has full recovery properties after 100% elongation and lends elasticity and flexibility to the sheet. The inorganic fiber glass reinforcement, in conjunction with the polyester, provides stability, toughness and puncture resistance to the product and resists moisture absorption. The reinforcement also provides high tensile strength and affords better natural resistance to the other factors which affect roof performance. The covering layer of a white, acrylic coating combined with ceramic-coated roofing granules, provides durability along with superior resistance to damage from weather and foot traffic and the benefits of a reflective, emissive surface.
DynaKap FR CR is designed for use as a premium modified bitumen sheet in multiple-ply roofing systems. It is ideal for low-slope applications (inclines up to 1/2" per foot [41.6 mm/m]), and is recommended for this application with Types III and IV asphalt. For slopes from 1/2" to 3" per foot (41.6 to 250 mm/m), only Type IV asphalt is recommended. DynaKap FR CR may also be installed in JM MBR® Cold Application Adhesive. Because of its superior weatherability, durability and handling characteristics, DynaKap FR CR may be used both for a finished cap sheet and as a flashing material; however, we require using DynaFlex® for flashing applications in many specifications. This product is not to be installed using heat-welding application techniques.
