With only 1 layer of glass then sleeving would be a must. The top I pictured earlier weigh's less then 120# The bases of the piping are 3.5 inches diameter and there are 3/4 " diameter washers on the top. No dimples anywhere in the glass. If one decided to use balsa then I probably would agree that sleeving to prevent water intrusion would be a good idea. I dont think Balsa is a good idea on a roof especially when there are so many other good products out there....just saying...
