: Searched the archives and websites referenced already and haven't yet quite
: figured out the different glasses. Could someone comment(or suggest
: websites) on the different glass options...E vs. S vs. ? ...and their
: advantages or disadvantages. Many thanks....Bob

In general, E-Glass is what we typically use on our boats. I believe the "E" stands for electric, maybe from its early historical use as an insulator.

S-Glass, as in "Structural", maybe? It's something like 30-40% stronger than E-glass for the same weight. It costs quite a bit much more, certainly more than 30-40%.

I know Fiberlay in Seattle, WA, carries the 5.2 oz. weight of S-Glass. You might also try Fibre Glast at:

One or the other should get you started.
