The Bank of America high-rise building was constructed in 1985 and is the tallest structure in the Dallas-Fortworth metropolitan area. In 2010, Curtain Wall Design & Consulting (CDC) detected some deterioration of the original neoprene window gaskets, which were leaving a dusty residue on the side of the building. They designed a 5-year plan to complete repairs on all 18,000 panes of glass.
Initially a wet-seal repair was recommended, but there was a big caveat. The team predicted that some of the insulated glass units (IGUs) would need replaced in the near future and later replaced. To avoid this, CDC opted for a full gasket replacement.
Upon further investigation, it was discovered that Tremco had manufactured the original neoprene gaskets, which had lasted over 35 years. This provided the assurance that Tremco's proposed silicone solution would offer the high-performance and longetivity needed.
Tremco unique's Poly-Wej design was customized for this project with a larger relief hole and angular length which accommodated the other glazing components. Poly-Wej gaskets are commonly used in compression gaskets systems. Ultimately, the silicone wedge gaskets with Tremco's Spectrem 2 silicone sealant offered a less intrusive and higher-performing solution than a wet-seal repair.
