We have developed an at-a-glance comparison matrix that demonstrates the different ways that Sprung tensioned membrane structures outperform and outlast pre-engineered metal and conventional construction buildings.
How Does a Sprung Structure Compare?
|Feature||Sprung Structure||Pre-Engineered Metal Building||Conventional Construction|
|Delivery||Normally 3 weeks from order||6-16 weeks from order||8-12 months|
|Shipping||Compact shipping: up to 15,000 sq.ft. can be shipped in one 40′ ISO container or on one 48′ flat bed.||6,000 sq.ft. per load||n/a|
|Foundations||If appropriate soil conditions exist, concrete foundations are not required on structures up to 160′ wide||Yes – no exceptions||Yes – no exceptions|
|Construction time on building envelope||500 to 2000 sq.ft. per day depending on options complete with finished interior||After foundation is in place, up to 8,000 sq.ft within 4 weeks||12-18 months|
|Overall fast track construction timeline. Ground breaking to completion.||1-6 months||6-9 months||12-18 months|
|Maintenance schedule||Rust free aluminum substructure. Patented tensioning system does not require any retensioning of membrane panels for the life of the structure.||A standing seam metal roof is prone to large thermal movements. This causes leaks and requires continuous maintenance, especially at penetrations.||Regular maintenance is required.|
|Expandability||Adding additional modules is easy||Renovation required||Renovation required|
|Exterior color options||Unlimited||Limited||Limited|
|Flexibility to relocate||Yes||No||No|
|Daylight panels||Standard feature: daylight panels in peak provide an optimum amount of natural daylight||Significant extra cost||Significant extra cost|
|Airtight building Envelope Efficiency||Air permeability is almost 0, resulting in superior energy performance.||Poor air-tightness||Moderate air-tightness|
|Acoustics||Excellent acoustical properties with our comprehensive insulation package and “soft wall” interior membrane||Significant additional costs associated with acoustic treatments needed to make a metal building acceptable for any application where acoustics are a concern (gymnasiums, public assembly, churches, casinos, offices etc.||Limited performance|
|Lifespan||Indefinite lifespan simply by replacing exterior membrane every 20-30 years depending on membrane selection||15-50 depending on quality level||Replace roof every 25+ years|
