need4speed Posted April 25, 2013 Share Posted April 25, 2013 Is there any way to tell if foam is closed or open cell? I have a large roll of self adhesive foam strip in the workshop that i would like to use for seals etc but obviously i would prefer it to be closed cell so it doesnt hold moisture (for obvious reasons). Is there any way to tell which is which? Quote Link to comment Share on other sites More sharing options...
