An Introduction to the Industry Leader in SBS-modified Bitumen

 

For more than 35 years, Siplast has been a leader in the development and manufacture of the world's most advanced roofing and waterproofing systems. A member of the Icopal Group, one of the world's largest commercial roofing manufacturers, Siplast has a history of innovation. 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/recovery properties over a wide range of temperatures.

 

There are Siplast roofs applied in the early years of our SBS blend that are still in service today. Since then, Siplast Engineered Roof Systems have been applied over all types of deck constructions, in the extremely varied weather conditions of more than 40 countries. Over the years, Siplast SBS-modified bitumen roofs have changed the least, lasted longer, and performed better than anyone else's.

 

Complete Roofing and Waterproofing Solutions

Siplast offers complete roofing and waterproofing solutions that include all of the accessory components necessary to build a great system. Whether it's edge metal, roofing fasteners, or sealant, you can be assured that Siplast accessories have been designed and manufactured to work with Siplast SBS-modified bitumen membranes.

 

Siplast is the only commercial manufacturer to offer a roof system package that combines SBS-modified bitumen membranes with the added benefits of lightweight insulating concrete. Siplast's SBS-modified bitumen roof membranes have a long performance history over lightweight insulating concrete. Our experience has shown that the insulation's encapsulated design provides a stable, monolithic surface for the roof membrane system. It has also demonstrated that the relatively high density of Siplast Lightweight Insulating Concrete can positively affect membrane life by impeding extreme temperature fluctuations and the resulting thermal stresses that can cause membrane fatigue.

 

Used together, Siplast SBS-modified bitumen roof membranes and Siplast Lightweight Insulating Concrete Systems result in a longer lasting roof. And, since Siplast Lightweight Insulating Concrete Systems are re-roofable, significant cost savings over the life of the building can be realized.
