What is Z glassing

I have this on my 7’6" funboard and no one seems to know exactly what it is. Is it stronger, more flexible, or tougher than S or E glass? Why use it? Thanks

Z glass has been around for ages. They used to make those flexi skateboards out of it, which is how the Z boys got their name.

so is it better or worse than s or e glass?

Bean, I think you might be mistaken on this one. Maverick, more info please. Hey any of you skateboard guys buy any material from Gordon Composites? www.gordoncomposites.com They make some great high strength precured materials for press molding. G&S flex boards used this material (Larry G’s family, hence the name Gordon Composites). Sluggo
