Fiberglass

Johns Manville Engineered Products manufactures fiberglass in the United States and Europe. We offer engineered fiberglass in chopped strand and roving to a variety of applications, to extend the capabilities of thermoplastics and thermosets, and to reinforce gypsum boards.

ThermoFlow® chopped strands exhibit exceptional strand integrity, clean feeding, and uniform fiber distribution.

StarRov® single-end roving is perfect for fabric processes as it provides a wide and uniform strand width which allows to produce a superior fabric without gaps. StarRov® single-end roving is also the perfect choice as an input for LFT or D-LFT processes, providing excellent mechanical properties, low VOC, perfect bundle opening, fast impregnation, perfect wet-out, high dry strength, and low fuzz.

For SMC processes, MulitStar® multi-end roving provides excellent fiberglass distribution, wetting, bonding, and SMC performance. For thermosets MultiStar® multi-end roving is optimized for chopping and excellent performance in long-fiber reinforced polyurethane panel production, offering excellent unwinding at high speed, great choppability, and low fuzz generation during processing.

Finally, our DuraCore® wet chopped strand is boosting the properties of plasterboard in key areas such as fire performance as well as water and impact resistance.
