Prisma Composite Preforms Hull Lumber

Prisma composite lumber is fiberglass material with a non-woven polyester backing that features a 2 PCF flotation grade polyurethane foam. Commonly used in conjunction with structural members and stringers, and hull stiffeners. Available in 2 sizes to suit your application.

Common installations usually only require a simple, three-step process. Wet out the underside of each Prisma beam, position them where desired, wet out the top side of each beam, roll the tabs, and you're done. Prisma preforms saves time, material, and labor costs on just about every installation.
