A: HI JP, In all my years in this Business, I have never come across a request of sort. If you have the right Bit/Bolts,etc. and are able to Cut the Round hole to accommodate the vent Pipe to penetrate the Glass Block without Cracking the Glass; I suppose that its Possible. * I don't think it's feasible and worth your time and effort! **** Your best bet is to inquire a Glass company (Installer) Good Luck! "The Best One"
A: I’m not sure, it would depend on your glass block; size of opening, does your block allow for attachments/venting, etc.
