Windshield Thickness

[Devilman]

I've got a customer that's having a glass manufacturer build him "quiet" glass for his windshield, rear window and sides for his crew cab like they use in higher end luxury cars. The stock windshield was 6mm if I remember correctly when I got him measurements. Haven't gotten the new glass yet but I'm sure they'll be as thick or thicker than stock on the front and rear, the sides are suppose to be 2mm thicker than stock. Not sure how well it'll help with quieting down the truck but we'll see....I know it's definitely a LOT more expensive than factory replacement glass lol
