Siplast Roofs: An Investment for the Future

Some building owners and specifiers who know about Siplast and would like to have a Siplast roof are under the impression that they can’t afford one. They’ve heard that a Siplast roof can cost more than some of the alternative roof systems on an installed cost basis. They’re not sure it’s worth it.

Paradiene 20/30 SBS-Modified Bitumen Membrane Systems: The Importance of Ultimate Elongation & Cyclic Fatigue

There are certain physical properties that a high quality SBS-modified bitumen system (e.g., Siplast Paradiene 20/30 system) has that help enable it to maintain performance over decades of service on a roof. It starts with the asphalt blend, which drives some of the physical requirements for long term performance. The reinforcement combined with the upper and lower layers of SBS-modified bitumen determine the primary physical properties and performance characteristics of the sheet. In other words, what Siplast does prior to and during manufacture of the Paradiene 20 and Paradiene 30 sheets is a huge part of what leads to the roof’s potential long service life.
