Siplast has been providing high performance, long term solutions to commercial roof owners since the 1960′s.

While it has been said that imitation is the highest form of flattery, when it comes to the serious business of roofing, we just don’t think so. Many newcomers have tried to imitate Siplast’s industry leading products but end up using their customers’ roofs as guinea pigs in the testing and evolution of their products, which can sometimes end in disaster for the customer. There’s just too much at stake to let others experiment with their products on your roof.

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.

From time to time, details can not be properly addressed with conventional flashing methods. In situations where standard flashing treatment is labor intensive, it can be cost prohibitive. In other cases, continual maintenance may be required due to the products used. Projections can be in locations that are difficult to access, making traditional flashing methods impractical.

The Siplast Parapro 123 flashing system was developed for these challenging circumstances.

Self Adhesvie Paradiene 20 SA is your answer to an application method and material that allows maximum installation efficiencies and an result in increased productivity and labor savings.

Do you have a waterproofing need? Try Siplast Terapro, made with PMMA, the same material used in countless high performance applications such as dentures, bone cement, airplane windshields and hockey pucks. PMMA material is also proven highly effective in uniquely challenging waterproofing applications.

Teranap is a multi-ply system. The torch-applied, two-ply Teranap System is based on proven roof membrane design. The elastomeric base ply, Terabase, is engineered to retain its elasticity through the rigors of deck movement. The top ply, Teranap, consists of a nonwoven polyester mat impregnated and coated with SBS-modified bitumen. The surface of the sheet is protected by a polyester film.


Siplast Lightweight Insulating Concrete Systems combine the unique properties of lightweight insulating concrete and Insulperm premium expanded polystyrene foam insulation board. Siplast Lightweight Insulating Concrete is available in four mix designs: ZIC, NVS, Insulcel, and Zonocel. The four designs represent a range of compressive and tensile strengths, allowing a choice of system based on substrate and specific project circumstances. Each design encapsulates the insulation board in insulating concrete. This process provides fire protection, prevents air infiltration, and bonds the total insulation system to the substrate. Unlike rigid board, Siplast Lightweight Insulating Concrete is reroofable, and therefore a truly sustainable insulation solution.
