[General Baxter]

[Asa-James]

3 - 4 mm?

[mowgli]

General, I assume you mean car glass???? just wind one down & have a look.

[Jack]

3mm. Just measured it.

[Ash]

If you're thinking of making perspex windows then, your probably better off with 5mm, plus then its FIA approved ;)

[Iain]

I thought 4mm stuff was FIA approved too? Just no thinner.
