Multi-Ply SBS-Modified Bitumen Membranes
In the late 1960s, Siplast Research and Development, working in conjunction with Shell Chemical of Europe, developed SBS (styrene-butadiene-styrene) modified bitumens. We found that by properly modifying asphalt with SBS, we could produce a highly durable elastomeric blend with exceptional elongation and recovery properties over a wide range of temperatures. This technology was applied to the design of our two-ply engineered roof systems, in which the workhorse base ply absorbs roof stresses while the top ply shields the base from the elements and mechanical abuse.
Single-Ply SBS-Modified Bitumen Membranes
Designed especially for sloped roofs, Siplast Parafor 50 is a single-ply roof membrane comprised of a base material that is a blend of elastomers and high- quality asphalt with a fiberglass-reinforced polyester mat. The result is a tough, flexible sheet with the stability and strength of fiberglass and the puncture resistance of polyester.
PMMA Liquid-Applied Roofing
When project circumstances, local regulations, or a tight construction schedule make the application of roofing sheets difficult, Siplast offers a proven high-performance option: liquid-applied Parapro Roof Membrane. Parapro Roof Membrane is a seamless, fully reinforced waterproofing system that can be used in conjunction with Siplast Paradiene roof membranes, as a stand-alone alternative to more traditional roofing plies, in bright white cool roof applications, or for waterproofing challenging vegetated roof systems.
