Johns Manville - Reinforcement


Glass fiber reinforced plastics are an integral part of today’s environment. Without them, many technical applications would be unthinkable. Low weights, stiffness and longevity – without glass fiber products, these reinforced plastics which are used in technical areas like the automotive or shipping industry but also in construction and consumer goods for the home and leisure time would not be feasible.

The comprehensive product range offers tailor-made solutions for the glass fiber reinforced plastics industry, ranging from chopped strands to assembled rovings, direct rovings and chopped strand mats.

Johns Manville is committed to the reinforced plastics market. Continuous investments and introduction of new products highlight our business strategy: Looking at Innovative Growth.
