Structural vs. Non-Structural Fiberglass Shelters

At the core of each Openchannelflow Structural Fiberglass Shetler is our proprietary X-web construction. X-web technology allows Openchannelflow to bond exterior, interior, and intermediate fiberglass laminates together in such a way as to form I-beams and webs of interconnected, chemically bonded scaffolds within which insulating and reinforcing cores can be placed.

Comparing Non-Structural Fiberglass and Structural Fiberglass Shelters

By bonding the various laminates layers together, Openchannelflow’s structural fiberglass avoids the weak point of a non-structural fiberglass shelter - the insulating foam – carrying any wind, snow, or seismic loads. The result is a structure of superior strength, stiffness, and rigidity – one that is able to withstand far more severe operating and weather conditions than a similar non-structural fiberglass shelter.

Now some manufacturers try to get around this “stressed skin” problem by utilizing a wooden framework of 2x4s – between which they install fiberglass sheet or batt foam which they then cover with fiberglass sheets.

These sheets are attached to the wooden framework with construction adhesive, with corners capped off with trim pieces.

Overtime, unless the adhesive is expertly applied, the fiberglass sheeting and trim pieces can delaminate for the framework, compromising the shelter’s integrity and exposing the load bearing structures to pests, vermin, rot, and decay.

Even when the panels stay bonded to the framework, penetrations through the fiberglass skin, whether intentional or unintentional, can allow humidity and atmospheric corrosion to being to break down the structure.

With Openchannelflow X-web technology panel design to ensure maximum strength and durability, our structural fiberglass shelters are a selected choice and used in a variety of industry applications throughout North America and around the world.
