Heck I don't know what this stuff is called. You know....the vertical plastic strips that are used in butcher shops to act as a thermal barrier between a refrigerated space and a space that is not refrigerated. I would like to get my hands on some of that stuff to create a similar barrier between a one car garage (my shop) and an adjacent (but perpindicular) two car garage. The opening between them is about 6 feet wide and I would like it to decrease the amount of sawdust that would otherwise find its way into the two car garage and layer on the cars there (as well as aid in climate control). Any ideas where I can acquire this stuff? Any idea what its called?
