I'm trying to build something or find something at home to store my windows in. How tight can I roll up my side windows. I wont wanna break the plastic thingy, especially since it's still a bit chilly here. I've seen some things roll them up pretty tight so I'm guess there is no real limit. Thanks

 

well the key is going to be the outside temp when you roll em up. I once shattered, yes shattered the rear zip out window tapping it from the inside to remove the snow in the winter. If they're cold enough they'll break, if its warm out, they're very plyable and should roll up as tight as you want. I often roll em up to about a 5 inch circle and stuff em under the rear seat when the doors are on. so i would think it its warm enough to be taking the windows off, you should be safe to roll em up pretty tight

 

X2 What he said. Just don't fold em or kink the plastic,
