Hi David
Thank you for your response. I have read the 2 links you posted on artglassanswers but I was mostly interested in getting supplier info.
I have also opened the links you provided but for some reason my computer comes up with a warning each time that the site may infect my computer - it has done this in my earlier searches also so I have not attempted to enter the site
Would you have any other supplier recommendations? Also what is a squirrel cage fan? I did a search for this on Home Depot's site earlier and all it came up with was a squirrel have-a-heart trap
Sorry for all the questions, I just want to make sure I get the correct set up- I have been at this way too long without proper ventilation.
