Asked by Garrett December 24, 20191
AnswerGarrett, We'd love to sell you 87 bags :), but you don't need that many. Each bag of R-21 has 7 batts, so the number of bags would be 87/7=12.4. You'll need to buy 13 bags for the project. Good luck and thank you for considering Johns Manville product for your project.
