Fountain Square

eBay Headquarters

San Jose, California

Investigation of the PIB sealant migration problem into the insulating glass units (IGUs) that are integrated into the curtain wall of Building 17 at the eBay’s Corporate Park. Field observation, photographic survey of each elevation of the building envelope, limited temperature survey of installed IGUs, IGU sample removal, independent laboratory testing, and a review of the design drawings were conducted. PIB migration and runs occurred due to viscosity changes in the material, resulting from chain-scission-induced molecular weight loss, indicating defective PIB material.
