Caulk for studio glass?

Hi everyone. I've finally finished the dead air space and have the frames built and ready for the glass. I have butyl tape and rubber setting blocks but trying to figure out what caulk to use. Should I use a butyl caulk? Thanks.

Just use transparent sylicone caulk

Thank you Jbassino for responding. Do you mean like GE silcone 1 o :shock: r 2 clear, the cadillac of caulks? I have a lot of the silenseal caulk that stays flexible but I guess in this situation, I don't really want that?

I dont know your brands, I live in Chile But you do want flexible caulk, always!

I wish I lived in Chile. I have a friend in NY who tells me it's the most beautiful place in the world! Anyway, I guess I'm begging for someone else to chime in here-is silenseal acoustic caulk too flexible for setting the window in the frames??? PLEASE

Clear silicon is typical to set glass. You want to make not only a seal but create a bond to keep the glass from being a loose element in the window hole...eliminate the rattle. This is in >typical< construction which is not what you are doing right? That said, you will want to review what Eric Desart has to say so you may get a better understanding of what you gain what you lose and where you may lose and or gain it from :) "If it bounces back = no good (depending on appliction: more or less important). Silicone bounces back as a perfect ball. " LINK: http://forum.studiotips.com/viewtopic.p ... 61&start=9

Hi Xspace. Thanks's for responding again! Basically, I have 1/8" rubber setting blocks and butyl tape. The Butyl tape will be placed on three sides of the glass all around the parameters. (Actaully, they'll be attached to the wood) The setting blocks are for the bottom to prevent the weight from the glass from working through the thick butyl tape to the wood. Once the glass is pressed against the inside wood frame, the other outside part of the frame, with butyl tape attached will be pressed against the glass and finished nailed in. But it seems a bead of caulk is appropriate to seal any air that the goopy butyl doesn't seal. I have cans of this "Silenseal" caulk that does not "bounce back" and remains slightly soft for ever or I can use Silicone caulk which makes an air tight seal but does have the "bounce factor". Which would you use? Thanks again for your advice!
