About Siplast

Our story: from innovation to industry leaders

The Siplast story is one of uncompromising quality, innovation, partnership, and commitment to our customers and their communities. Our story began in the late 1960s with a game-changing innovation: the development of SBS (styrene-butadiene-styrene) modified bitumens. This breakthrough — the result of close collaboration between Siplast Research and Development and Shell Chemical of Europe — found that the proper modification of asphalt with SBS produces a highly durable elastomeric blend with exceptional elongation and recovery properties across a wide temperature range. Since then, Siplast Engineered Roof Systems have been applied across all types of deck construction in the varied, sometimes extreme, weather conditions of 40+ countries.
