I’m in the process of doing some butt glazing ( butting two pieces of glass togeather with a silicone seal between them ) and would be intrested in finding out how some of you with this type of experiance are doing it. I have tried it two ways – 1. putting the silicone on the butt joint and pushing them togeather and 2 – pushing the glass panels togeather with appx. 1/8″ space between and caulking after the glass is secured. The first method seems to be too messy when I’m trying to get a smooth, small bead at the finish end of the job. # 2 method seems to work OK but I’m wondering, what is the minimum space between the glass panels and what is the maximum ?
