Pound for Pound Stronger Than Steel–No Delamination!

All of our fiberglass shelters and buildings use FiberBeam Technology, our innovative, proprietary composite lamination process that bonds inner and outer fiberglass skins with a series of integrated fiberglass I-beams. The beams are spaced every 12” throughout the walls, doors, and roof, resulting in a fiberglass composite building system that is equal to the strength of steel.

Foam is a great insulator but not a good structural material. That is why we developed FiberBeam™ Technology. When a typical FRP panel with foam core is placed under a load the bond between the foam and the FRP is put under stress and can fail. With FiberBeams thesame panel is more rigid and can withstand much higher stresses without any bowing or buckling.


Hello, my name is Tracy Switzer, and today I’m here to answer the question, “What is FiberBeam, and why is it important?” This sample panel is typical of how fiberglass buildings are constructed. There’s a fiberglass layer on the outside, a fiberglass layer on the inside, held together by two pound density foam board. Foam is a wonderful insulator but it is not a structural component, easily broken. Even when you put it between layers of fiberglass, it’s still not a structural material. A Shelter Works building is expected to last through cycles of extreme temperatures, high winds and heavy snow loads, and last for decades. That’s why we developed our exclusive FiberBeam technology. Fiber beams are essentially integrated fiberglass I-beams that create a structural link between the interior and exterior fiberglass skins. We space our fiber beams 12 inches apart through every wall, every door, and every roof that we build. Even under a concentrated load, there’s almost no deflection. This creates a more structurally sound building. At Shelter Works, the integrity of our company is expressed through the integrity of our shelters. If it was built by Shelter Works, it was Built for Life
