Abstract:
A method of securing a plurality of mullion sections to a plurality of building anchors, each of said mullion sections capable of supporting a portion of a curtain wall assembly, said method comprising:attaching a first mullion section to a first building anchor assembly such that said attached first mullion section is capable of upwardly supporting a portion of said curtain wall assembly; slidably attaching a second mullion section to a second building anchor assembly such that a lower end surface of said second mullion section is spaced apart from an upper end surface of said first mullion section by at least about 0.2 cm and said attached second mullion section is capable of sliding upwardly relative to said second building anchor assembly when supported by said first mullion section; and wherein contact between said first and second mullion sections is capable of sliding said second mullion section upwardly relative to said second building anchor and limiting further relative compressive motion between said mullion sections.
