The pvc membrane is approximately.025 inch It’s very tough but very easy to patch if needed. Once patched properly it will not separate, it bonds itself permanently

Hey Paul, what kind of trailer are you working with? Generally when you say an enclosed trailer that would be a thin aluminum or sheet metal roof. This roof membrane is not necessarily intended for that application. There are other products you can use to seal your roof if it is in fact, metal or aluminum.
