Presentation TitleFire-Rated Expansion Joints – Principles, Products, Practice and Innovation Presented By David S. SorrellsArea ManagerEMSEAL Presentation Synopsis The breakthrough family of single-install, multi-function, fire-rated, waterproof, soundproof, hurricane-resistant, high movement expansion joint sealant technology will be discussed and contrasted with existing technologies and principles of the industry. In this presentation we will analyze how watertight, energy efficient, fire-rated expansion joints are the consequence of a process in which we: Design, Detail, Specify, Bid, Erect, Manufacture, and Install in 3-D. We will learn why it is critical to require certified performance and test reports from national laboratories in specifications. We will investigate how fire-rated expansion joints can contribute to sound attenuation, reduce energy loads for heating and cooling, eliminate high-emitting VOC’s, and save in materials and resources through long life-cycle material choices. We will discuss how to meet life safety obligations while practicing good building science.
