Yup. It WILL shatter, but then we commonly have weeks of subzero temps.

Wow! Thanks for the info! I never knew that.
Indiana does get quite cold. Haven't had this problem tho (or should I say yet!) I made a 4'X 8' one for a guy. He stapled it to plywood and hung the whole thing on a wall of a building. It's lasted 4 years so far. But at least I know there is a risk.

OOpsie - first a double post and then I realized you said coroplex not coroplast. - What's coroplex?

I've been using coroplast in hockey arenas around here for years because when it gets hit by a puck it tends to spring back leaving just a dent. Crezone is harder but doesn't recover from dents. The rinks will get down to -20 to -30F. I haven't seen it shatter yet, and if getting hit with a flying puck doesn't shatter it I'd think it is pretty stable. I've also unloaded it extremely cold weather from the back of a half ton after a 70 mile drive and never broke any. Throw some in your freezer overnight and check it out. There are also coroplast signs on our ball diamond fence and at the golf course and they are left out all winter. What are you wanting to use it for?

Bob lives in Florida, where your car's headliner melts off in the summer- do you consider "extreme Northern climates" to be Virginia, Bob? LOL
I had one guy tell me that he (in New Brunswick)had some Celtec break when the plow went by just from the impact of the snow (January), so yeah I would be careful of any plastic in weather north of about New York- I even saw a steel panel on a car shatter, not bend, in an accident in Montreal (-30 F).

I realize that sintra, celtec, komacel, all of your pvc sheet goods will shatter if hit in cold weather.
Coroplex is the thicker heavier duty version of coroplast. The plastic propeties appear to be more rigid than its cheaper 3mil sibling.
Would you say that the tendency for it to break would be only if it was hit by something? On its own if not tampered with, could you expect it to endure "just the cold" temperatures without any ghostly structural failure?

Ditto what Kelly says. We get really cold temperatures here, and the only time I have seen Coroplast ripped to small pieces was when someone glued it to a plywood backing. I have also used the 10mm (1/2")version for outdoor signs without any problems yet.

If well supported/mounted, or backed with plywood (screwed on, w/ oversized holes), it'll be all right. I wouldn't use it post mounted. Cold by itself doesn't affect it, but it will break easily at cold temperatures.

Bob I mis-understood..thought you meant comatex.. We use coroplast all the time here... it works fine... It gits down to zero or below... No problems ever. And scraps are used for mailing containers If the weather cant break it... and its Postalworkerproof... must be tuff stuff!!!!

We don't have the extreme cold problem down here with Coroplast (Corflute we call it)
But it does break down under UV rays! I had a customer with a "temporary" 3mm corflute sign screwed to a wall for 5 years. When I went to replace it with something more permanent it just crumbled in flakes.!
Same customer complained that a sign I had painted had faded badly. It was also 5 years old. Turned out to be a quick ($30) blackboard splash in poster paints!!!! "1/2 PRICE SALE ... THIS WEEK ONLY" hahahahaha
