Compare Shelter Works Shelters to Non-Structural Fiberglass

That is why all of our fiberglass shelters are built with our proprietary FiberBeam™ Technology.  Our shelters do not rely on low density foam for the structural support of the composites that make up our walls, roofs and doors.

Without Fiberbeam

There are several manufacturers of FRP (fiberglass reinforced plastic, A/K/A fiberglass) buildings that you might think are all roughly similar in construction- rigid sheets of low density foam laminated between two layers of fiberglass, known as a stressed skin sandwich panel. It has been done like this since the early days of FRP and it makes for a nicely insulated structure. Even Shelter Works used this technique early in its history, until we began experiencing some delamination that we had to fix under warranty. Something had to be done to solve the problem systemically.

We reasoned that no matter how well you bond foam to FRP the bond is only as good as the molecular strength of the weaker of the two materials – the foam. And frankly the foam is not a good structural material and should not be relied upon to ensure the integrity of the building.

Shelter Works Building FiberBeam Technology

FiberBeams are essentially fiberglass studs, spaced not more than 12” apart, that are integrated into all of our walls, roofs and doors which serve the function of providing a solid, structural connection between the inner and outer fiberglass skins of our buildings. They are not additional pieces, but rather are integrally formed during the lamination process resulting in a composite panel that can never come apart, or “delaminate”.

Our customers know they need strength, and they love the longevity provided by fiberglass…But many have experienced the frustration of other manufacturer’s products delaminating or not holding up to the strength requirements they really need. That’s why they have turned to us…because really, FiberBeam™ Technology is long-term structural peace of mind.
