We live in a dynamic environment, but until now our building enclosures have been static in nature – unable to effectively control the flow of the sun’s light and heat into buildings from hour to hour and from season to season.
A survey of sealant types and chemistry with a focus on selection basics, failure modes, and differences between sealant choices.
As the trend toward re-using buildings grows, re-skinning buildings will become ever more prevalent. Presenters from SERA, Howard S. Wright, and Benson will give a very brief presentation and then a tour of the building emphasizing the story of the envelope. The tour and presentation will tell the story of the project and the envelope.
Traditionally precast panel wall assemblies have been designed as face seal systems. In these systems weather tightness relies on water repellence treatment of the panels and on the detailing of the panel joints, such as binary sealant joints. More recent designs have attempted to incorporate rainscreen principles in the design of precast panel wall assemblies.
