Splice joints should occur at spandrel areas. D.
Series 5900 Silicone Structural Glazed Curtain Wall Installation V: Vertical Splice Applications Vertical Splice Joints at SSG Verticals and Captured Horizontals Splice should occur at the spandrel areas. B.) Fabrication Note: Match drill the splice for shear block attachment. C.) Splice Note: The vertical mullions that are structurally glazed must be spliced at the horizontal locations. (All mullion splice locations must be reviewed by a factory engineer.) 2 1/2" A.
Series 5900 Silicone Structural Glazed Curtain Wall Installation V: Vertical Splice Applications Vertical Splice Joints at SSG Verticals and Horizontals A.) Splice should occur at the spandrel areas. B.) Fabrication Note: Match drill the splice for shear block attachment. 2 1/2" C.) Splice Note: The vertical mullions that are structurally glazed must be spliced at the horizontal locations. (All mullion splice locations must be reviewed by a factory engineer.
Series 5900 Silicone Structural Glazed Curtain Wall Installation VI: Glazing Preparation Glazing Preparation at Structural Glazed Mullions Note: All thermal isolators should be removed from the reels and allowed to shrink prior to installation. Prior to installing the mullion plugs, seal all three sides of the pocket, making sure all cavities are filled. Install thermal isolator prior to installing the mullion plugs.
Series 5900 Silicone Structural Glazed Curtain Wall Installation VI: Glazing Preparation Glazing Preparation At Captured Mullions A.) Install the thermal isolator in the vertical mullion, run continuously, and butt joint as required. B.) Seal vertical mullion raceway 1” long prior to the installation of the joint plugs. C.) Place and seal the joint plug. D.) Tool off all excess sealant. E.) Apply sealant to the face of the joint plug prior to installation of the pressure plate. See page #19.
