Fabric buildings are transforming agriculture, storage, and industrial operations across Canada and the U.S. Known for their strength, flexibility, and light-filled interiors, these structures offer an affordable alternative to traditional steel or wood buildings. Whether you need a barn for livestock, a warehouse for equipment, or a salt storage dome for your municipality, fabric buildings provide a fast, durable, and cost-effective solution.
This guide explains everything you need to know — from cost and durability to foundations, codes, and applications — so you can decide if a fabric building is right for your project.
What Is a Fabric Building?
A fabric building is a tensioned membrane structure supported by a steel frame. Instead of metal panels or wood siding, the roof and walls are covered with a high-performance fabric designed to allow natural light while withstanding harsh climates.
Compared to conventional construction, fabric buildings are:
Faster to install
Lighter, requiring simpler foundations
Naturally brighter inside, reducing energy costs
Flexible and expandable for changing needs
MegaDome fabric buildings combine an oval-tube steel frame with an exclusive agricultural membrane, creating a structure that is both robust and light-filled.
Types of Fabric Buildings
Agriculture
Livestock barns, hay storage, equipment sheds, grain storage. The natural light improves animal well-being and reduces electricity use.
How Durable Are Fabric Buildings?
Durability is one of the biggest questions buyers ask. MegaDome fabric buildings are engineered for Canadian winters, with steel frames that last decades and membranes designed for up to 20+ years depending on use and exposure.
Steel frame lifespan: 30–40 years with minimal maintenance.
Fabric membrane lifespan: 15–20 years, easily replaceable when needed.
Snow/Wind resistance: Site-specific engineering ensures compliance with snow loads, wind loads, and seismic conditions.
Corrosion protection: Galvalume + Powercoat finish, hot-dip galvanization for lower sections.
Result: a building that holds up against snowstorms, high winds, and daily agricultural use.
How Much Do Fabric Buildings Cost?
Fabric buildings typically range from $10 to $25 per square foot, depending on size, foundation type, and accessories.
Factors influencing cost:
Size & profile: Wider spans require stronger framing.
Foundation choice: Concrete vs ground screws vs blocks.
Membrane type: Standard vs high-performance light-transmission membranes.
Accessories: Doors, ventilation, insulation.
Compared to steel buildings, fabric structures are usually 30–50% more affordable upfront and much quicker to install.

Foundation & Installation Requirements
Fabric buildings can be anchored on:
Concrete slabs or footings
Installation is faster than conventional buildings — often a few days to a few weeks depending on size. MegaDome crews ensure correct tensioning of membranes and compliance with engineering stamps.
Another advantage: these buildings can be relocated or expanded as needs change.
Insulation, Heating & Climate Control
Fabric buildings are naturally bright, reducing lighting costs. For heated applications, they can be insulated and paired with mechanical systems.
Insulation options: Liners, rigid panels, spray insulation.
Heating systems: Radiant, forced air, or geothermal.
Ventilation: Sidewalls, ridge vents, or mechanical fans.
MegaDome’s exclusive agricultural membrane transmits 30% more natural light than standard membranes (16%), lowering energy costs and improving productivity. For livestock, studies show more light enhances animal welfare.
Do Fabric Buildings Meet Building Codes?
Yes — when supplied by a certified manufacturer. MegaDome buildings carry:
CSA A660 certification
ISO 9001 quality management
Site-specific engineering stamps for snow, wind, and seismic loads
Municipalities across Canada and the U.S. recognize these certifications, making it straightforward to secure permits.
Common Applications of Fabric Buildings
Fabric Buildings vs Conventional Steel Buildings
| Feature | Fabric Buildings | Steel Buildings |
|---|---|---|
| Cost | $10–$25/sq ft | $25–$50+/sq ft |
| Light Transmission | 30% (MegaDome) vs 16% standard | Requires windows/skylights |
| Installation Speed | Days to weeks | Months |
| Durability | Frame 30–40 yrs; Fabric 15–20 | 40–60 years |
| Flexibility | Relocatable, expandable | Permanent only |
Fabric buildings offer speed, affordability, and natural light. Steel buildings remain the choice for extremely heavy-duty or permanent applications.
Frequently Asked Questions (FAQ)
How long do fabric buildings last?
Frames: 30–40 years. Membranes: 15–20 years (replaceable).
Do fabric buildings leak or sweat?
Not if properly tensioned. MegaDome membranes are anti-condensation treated.
Can they withstand snow/wind?
Yes. Site-specific engineering ensures compliance with local codes.
Can fabric buildings be relocated or expanded?
Yes — one of their biggest advantages.
Do they require a lot of maintenance?
Minimal: tension checks, cleaning, occasional membrane inspection.
