The metal facade on the Columbus Regional Data & Technology Center had experienced leaks in the building’s exterior skin. Existing gaskets were failing and falling out. Western Specialty Contractors’ Indianapolis branch worked with the owner to tackle the problem.
Western decided to use Dow’s 123 preformed silicone tape over the metal-to-metal joints because of the extreme movement. Prior to installing the tape, Western completed a mock up sample for the owner and waited three months to determine if the material selection was correct for this situation.
Once the 90 days past, Western installed 6,100 lineal feet of 123 strips over the metal-tometal joints. Western also installed 1,500 lineal feet of wet glazing.
