Assembled Roving


Our Johns Manville DuraCore® chopped strands and DuraChop® roving were designed with high-quality gypsum board manufacturing in mind.  

JM chopped strands and rovings are ideal if you use a highly automated process where fiber dosing is critical for optimum gypsum board quality. Our quality fibers are also a great choice if you want a flexible operation to meet your regional demand, while improving the quality of your fire resistance performance.  Either way, JM has the gypsum solution for you.

We ship globally!  Contact a regional sales office for details.
