Presentation Title: 
The ‘Goldilocks Zone’ in sealing high-rise structures

​Steven Riggio, Chairman Emeritus at Riggio/Boron, Ltd
and President of Riggio & Associates Consulting

Presentation Abstract: 
In astronomy there is a ‘Goldilocks Zone’ where the temperature is ‘just right’ to support life. The same is true in sealing our buildings. Recent tests on sealant performance brought to light issues. A nationwide test program undertaken by some longstanding, highly respected members of the Sealant Waterproofing and Restoration Institute, SWRI, revealed unexpected results on modern day caulks. What started as an exploration into providing knowledge on color stability of caulking and sealants has expanded into apparent building movement induced by temperature change. This test program, executed by contractors under the watchful eye of an independent laboratory, Klosowski Scientific, exposes specific limitations on performance. The presentation will provide background on the overall test program and explore possible ramifications.

Presenter's Bio:  
Steven represents the second generation in the caulking and restoration business. His father started his company in 1972 and Steven has been involved since its beginning. He is considered to have highest level of expertise in the exterior restoration field. Steven is called upon to use this knowledge to innovate new approaches to restoration that provide the best cost and time savings for our clients while maintaining our strict quality and safety standards. His patented design for a silicone extrusion used on atrium skylights, glass window walls, panel roofing and curtain panel walls is just one example of his exceptional approaches to restoration and waterproofing solutions.
