Complete roofing and waterproofing solutions
Siplast is the industry leader in the development and manufacture of advanced, high-performance roofing and waterproofing systems. In the 1960s, working with Shell Chemical of Europe, Siplast developed SBS (styrene-butadiene-styrene) modified bitumens in response to the changing requirements of modern construction. We have always understood that different situations and times call for different and evolving solutions. That's why we also offer polymethyl methacrylate (PMMA) liquid resin products, single-ply systems, vegetated and reflective white roof systems, and reroofable lightweight insulating concrete roof insulation. Siplast is with you every step of the way to ensure your project vision fulfills the positive ways you want your work to impact the world.
