Alpine lights glass thickness?

Does anyone know the thickness of alpine light glass and the roof skin.
I replaced a seal awhile back with a Britpart one it has never been right so looking to buy some from a different source.

Need to know measurements before buying as diferent glass thicknesses and panel thicknesses available.

it might be different to a wind screen but they are around 6mm - the only reason I know this is we do cut front screens for customers out of 6.4mm laminated glass - they are always a little tight going in but as this is a stock item they are much cheaper and do the jo. The only thing making me think the alpine glass is less is the sheer bend on it! sorry carnt give any more info

They're not as thick as 6mm. I'll try and remember to measure some that I've got in my workshop tomorrow.

4mm

Thanks for that.
