Bad Homburg, Germany/Trnava, Slovakia (March 28, 2006) --- Johns Manville (JM), a Berkshire Hathaway company and a leading manufacturer and marketer of premium-quality building and specialty products will launch new products and expand its portfolio at the JEC Composites Show 2006 in Paris. The chopped strand mat MultiStar™ Mat ES 33-0-12,5 for Technical Applications, the assembled roving MultiStar™ 267, the long-chopped fiber strands StarStran® LCF 991 and the direct roving StarRov® 086 will be presented from March 28 through March 30 at the Johns Manville booth J17/J19 in Hall 1.

The company expects the MultiStar™ Mat ES 33-0-12,5 for Technical Applications, a specially developed powder-bonded chopped strand mat used in applications such as automotive headliners, to attract strong customer demand. The MultiStar™ Mat ES 33-0-12,5 allows the OEM to reduce the final part weight due to its mechanical performance. Based on a consistent fiber distribution at low grammages and stiffness, this new mat enhances design flexibility and allows for functional part integration.

The innovative assembled roving MultiStar™ 267, designed for SMC compound features unwinding and chopping characteristics that allow high SMC line speed as well as outstanding fiber flow during molding. MultiStar™ 267 is the preferred material used for LP/LS applications in the automotive as well as building and construction industries due to the superior quality of the final product's surface and its mechanical performances.

StarStran® LCF 991, a new long-chopped fiber glass strand specially designed for use in carding/needling and air-laid processes in combination with polypropylene polymers, is used to produce automotive interior and exterior parts such as trims, headliners, rear parcel shelves and truck liners. The product's consistent fiber diameter and length as well as controlled moisture content improve the productivity of carding/needling and air-laid lines through its processing behavior.

The direct roving StarRov® 086, available from 300 to 4800 tex, is designed for the weaving of multi-axial fabrics used for the production of wind blades as well as sporting goods and marine applications. StarRov® 086, compatible with unsaturated polyester and epoxy resins, demonstrates outstanding unwinding properties that result in less cleaning and machinery downtime and exhibits superior fatigue-resistant characteristics.

"The new and enhanced products in our portfolio show how much innovative energy JM has used to create additional value for our customers," states Mike Huff, vice president and general manager of Global Reinforcements for Johns Manville's Engineered Products Group (EPG).
