Frequently Asked Questions

We invite you to learn more about the innovative Sprung structure. Here are some frequently asked questions about the structure’s many features, its durability, efficiency, safety and more.

General Questions

Is it a tent?

No. The Sprung structure is an engineered stressed membrane structure, the result of more than three decades of research and development.

It is constructed of extruded aluminum arches, integrally connected to an all-weather outer performance architectural membrane. This specialized membrane is certified flame-retardant. Structures are engineered to withstand high wind loads and designed to shed snow.

With over a century of experience, Sprung delivers the most reliable, versatile and technically advanced structures available in the world.

What architectural features of the building make it superior?

As evidenced by the more than 12,000 installations worldwide, the Sprung structure benefits from lower capital costs, lower energy demands and lower life-cycle costs. Built with a 20-plus year performance architectural membrane and a non-corroding aluminum substructure, it also features exceptional durability and proven long-term performance.

What about vandalism and security?

Sprung structures are located in some of the worlds' most populated regions with no vandalism problems.

An optional 8½-foot-high Sprung Shield vandal-proof Hard-Wall system is available for extreme security-sensitive applications. Our performance architectural membrane has a ripstop construction that will help mitigate tearing should it be punctured.

Security is the same as for any building with windows. Motion detectors to set off alarms or to summon security or police are used in the same way as for other structures.

Can it be air-conditioned or heated?

Sprung offers a truly effective insulation system, using eight- or nine-inch R-25 and R-30 Johns Mansville fiberglass blanket insulation finished with an attractive tensioned interior finishing membrane.

What color choices do I have for the membrane?

There are many color options, all of which are proven colorfast and weatherproof. You can even mix and match colors at no additional cost by choosing an attractive wainscot.

How are the acoustics?

Sprung structures have been used successfully on hundreds of acoustically sensitive applications. The curved profile of the structure creates an interior free from conventional flat walls and corners. The soft interior fabric walls effectively absorb sound, resulting in outstanding acoustic properties.

Does it meet the building code?

The Sprung structure is designed to meet most building code requirements around the globe. Once you are ready to proceed, we will supply a comprehensive permitting package, complete with drawings and supporting calculations, all stamped by a licensed engineer certified in your region.

After placing your order, these drawings are provided free of charge for most applications.

Who oversees the project?

Once a contractor is chosen, our technical consultant will remain on-site during the build to monitor the project throughout construction to ensure quality is never compromised and your structure is erected to our exacting standard.

A Sprung Technical Consultant attends to your site from start of erection, to completion to ensure that your structure is erected to our engineering standards. 


How long will a Sprung structure last?

Sprung structures are built to last, withstanding extreme weather and extreme situations. The aluminum substructure has an indefinite life expectancy and a 30-year pro-rata guarantee. Our performance architectural membranes have pro-rata guarantees of up to 20 years. Future replacement membranes are inexpensive.

Design Flexibility

Can we change or add to the structure in the future?

The Sprung structure is a prefabricated, modular building design, which allows for easy expansion, or reduction, in the future.  

Can it be attached to an existing building?

Yes. The Sprung structure can easily be attached to an existing building through our sealed connecting corridor system, available in widths of 10’, 14’3” or 19’2”.  The structure can also be butted up directly to a conventional building.

How easy is it to relocate a Sprung structure?

One of the unique characteristics of the Sprung structure is that it can be dismantled, reconfigured and re-erected for a number of applications during the life of the structure. This is an easy and cost-effective solution.


Are engineering costs included?


Yes. You do not need to budget any extra for engineering of the structure itself, since it is included in the price of your Sprung structure.

Could we build a conventional metal building cheaper?

It is very unlikely that you could find a more cost-effective use of your building budget.

Please refer to our Comparison Matrix for more details. 


How fast can a Sprung structure be erected?

We inventory up to 2 million square feet of product for immediate delivery. Structures can be erected at a rate of up to 1,000 square feet per day for insulated structures, and 2,000 square feet per day for non-insulated structures.

The entire project takes a fraction of the time compared to conventional construction alternatives.

Energy Efficiency

Is the building energy-efficient?

The Sprung building system, with R-25 to R-30 ratings, outperforms other types of construction methods, resulting in improved year-round lower operational costs. There is almost zero air leakage which owes to Sprung's unique design and superior insulation.
