Key Industries

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

Reusable Siplast Lightweight Insulating Concrete Systems combine the unique properties of lightweight insulating concrete and premium expanded polystyrene foam insulation board. Available in four mix designs for a range of compressive and tensile strengths appropriate to different substrate or project requirements, each design encapsulates the insulation board in insulating concrete. The systems are fire-rated tested by Underwriters Laboratories in accordance with the procedures of ASTM E 119 and bond the total insulation system to the substrate, helping to prevent air infiltration. Unlike rigid board, Siplast Lightweight Insulating Concrete is typically reroofable, eliminating insulation removal and therefore not contributing to solid waste disposal. Siplast offers a complete roof system package that combines SBS-modified bitumen membranes with the stability and thermal performance of lightweight insulating concrete – ensuring the high performance you'd expect when quality products are designed to work together.
