The robust Paradiene System is a premium multi-ply SBS-modified bitumen roof system that performs and maintains its elasticity despite exposure to solar loads, substrate stresses, extreme temperatures, and random ponding water. Paradiene base and finish plies feature a uniquely formulated elastomeric asphalt-SBS polymer blend and are available with various reinforcement types. The Paradiene 20-series base ply is the working ply of the Paradiene roof system, absorbing substrate stresses and ensuring watertightness. Granule-surfaced Paradiene 30 FR or Paradiene 40 FR finish plies protect the underlying base ply from the elements.

The first SBS-modified bitumens... In the 1960s, Siplast® had an SBS/bitumen breakthrough in commercial roofing technology. By modifying bitumen (asphalt) with styrene-butadiene-styrene polymer (SBS), the resulting roofing products offered better elongation, recovery, and durability properties compared to other asphaltic roofing technologies. Since then, Siplast multi-ply Paradiene, Parafor, and Veral, Systems have been used on commercial building projects exposed to a wide range of climatic conditions in 40-plus countries. Today, Siplast SBS-modified bitumen solutions offer key advantages when addressing a wide range of project challenges. Combining a premium and consistent bitumen with optimized levels of polymer creates a foundation that has remained virtually unchanged for 40 years. Our unique manufacturing process, which includes combining compatible raw materials, provides an SBS membrane with exceptional weather resistance, flexibility, and longevity. Stringent testing also plays a pivotal role in our process, ensuring ultimate tensile strength, elongation, and cyclic fatigue recovery properties for long-term performance. The robust Paradiene System is a premium multi-ply SBS-modified bitumen roof system that performs and maintains its elasticity despite exposure to solar loads, substrate stresses, extreme temperatures, and random ponding water.
