Every farm buyer I talk to asks the same question, and it's the wrong one: "Which is cheaper?" The right question is "which costs less per season of use?" In agriculture that difference decides whether you're buying a covering or renting one. A PE tarpaulin at half the price that you replace every eight months can cost you double what a PVC tarpaulin costs over five years β and it does it quietly, one replacement at a time, in a line item nobody tracks.
This is the money math for farm coverings, not the spec sheet. If you want the general product comparison, that's a different article. This one is about your operating cost per square metre per year on a working farm.
Let me show you what a farm actually pays over five years, on a real specification: covering 1,000 mΒ² of silage and equipment, in a hot-summer, freezing-winter climate with intense summer UV.
| Cost line (5 years, 1,000 mΒ²) | PE tarpaulin | PVC tarpaulin |
|---|---|---|
| Initial purchase | $1,100 (180gsm, UV-treated) | $3,400 (650gsm, coated) |
| Expected service life | 1.5β2 years exposed | 5β7 years exposed |
| Replacements in 5 years | 3 sets | 0 (still functional) |
| Material cost over 5 years | $3,300 | $3,400 |
| Repair patches & labour | $380 (frequent, per set) | $120 (occasional) |
| Re-covering labour (3Γ vs 0Γ) | $900 | $300 |
| Spoilage from failed coverage | $600 (one rain event through a split) | $0 |
| 5-year total | $5,180 | $3,820 |
| Cost per mΒ² per year | $1.04 | $0.76 |
The PE tarpaulin looked 68% cheaper on the quotation. Over five years it cost 36% more. That inversion is the entire argument, and it's why "which is cheaper" is the wrong question.
Two caveats worth stating plainly. If you cover something for three months and never again, PE wins β you don't need five years of anything. And if your climate is mild with low UV, PE lasts much longer and the gap narrows. TCO cuts both ways; run your own numbers with your own exposure.
PE tarpaulins fail from the top down. The polyethylene film itself is degraded by UV, and while manufacturers add UV stabilisers, the stabiliser load is finite β it's consumed protecting the film. Once it's used up, the fabric embrittles and splits at the first real wind load. In high-UV regions, that's often the second summer.
PVC coated fabric behaves differently. The polyester base cloth carries the mechanical strength, and the PVC coating carries the weather resistance. UV hits the plasticiser and pigment in the coating; the base cloth keeps its tensile and tear strength far longer. This is why a PVC tarpaulin can look chalky and faded at year four and still hold a load, while a PE tarpaulin looks fine at year one and disintegrates at year two.
For agriculture this matters in a specific way: farm coverings don't just block rain, they're structural. They're strapped, weighted, and wind-loaded daily. A covering that loses tear strength is a covering that's about to fail in the one storm that matters.
Tropical wet season β a Malaysian livestock operation. Covering feed stores and open pens through monsoon. The failure mode here isn't UV, it's constant wet-dry cycling and microbial growth. PE tarpaulin grew brittle and developed pinholes within two seasons; the farm was patching monthly. PVC coating resisted moisture ingress and stayed flexible, and critically, the welded seams held β PE's stitched seams were the first thing to fail under repeated wetting. On this farm PVC's advantage wasn't lifespan alone; it was seam integrity in a wet climate.
Arid high-UV β a Middle Eastern date and fodder farm. This is PE's worst case and PVC's clearest win. Intense year-round UV consumed PE's stabilisers fast; two PE sets failed inside 18 months, one during a sandstorm that shredded it at the embrittled folds. The PVC covering, at 650gsm with a UV-stabilised coating, was still in service at year five, faded but structurally sound. Here PVC didn't just save on replacements β it prevented the covering from failing mid-storm, when a failed covering means exposed fodder in a sandstorm.
Temperate four-season β a European mixed farm. The most interesting case, because PE performed better than expected. Mild UV and only intermittent exposure let a good UV-treated PE tarpaulin last nearly three years. But freezing winters exposed PE's second weakness: cold embrittlement. Folding a frozen PE tarpaulin cracked it along the creases, and each winter's folding shortened its life. PVC stayed flexible at low temperature, so it survived both the fold-and-store cycle and the winter itself. PVC still won on TCO, but the gap was narrower β this is the climate where a careful PE user can justify PE for short-term seasonal covering.
Step 1 β Measure your exposure hours, not your seasons. A covering deployed year-round in high UV is a different product decision from one deployed eight weeks a year. Count months of sun exposure, not months of ownership.
Step 2 β Ask whether the covering is structural or shielding. If it's strapped, load-bearing, or protecting something that can't get wet, seam and tear strength dominate β that's PVC territory. If it just keeps dust off, PE's lighter weight is fine.
Step 3 β Price the replacement cycle, not the unit. Take your expected lifespan for each material in your climate and multiply by the number of replacements over your planning horizon. Add re-covering labour β it's real, and it's higher for the material you replace more often.
Step 4 β Add the failure cost. What happens if the covering fails in a storm? If the answer is "spoiled harvest" or "injured stock," weight the decision toward the material that keeps its strength longest. Post-failure cost usually settles the argument before the TCO table does.
Step 5 β Split the purchase where it makes sense. You don't have to standardise. Use heavier PVC for the critical, year-round, structural coverings and lighter PE for short-term, low-criticality shielding. Match material to consequence.
The most expensive mistake on a farm isn't choosing PE β it's choosing an under-specified version of either material. A cheap 140gsm "UV-treated" PE tarpaulin is a one-season product wearing a five-year label. Equally, a thin PVC tarpaulin with a light coating and a cheap base cloth will delaminate early no matter what the grade name says. If you've decided the covering is structural, put the money into the specification: for PVC, the GSM (650gsm and up for year-round farm exposure) and the base-cloth denier; for PE, a genuinely high UV-stabiliser load and reinforced hems. Material choice sets the ceiling; specification decides whether you reach it.
No. If your covering is deployed briefly, in mild UV, or shields something low-consequence, PE's lower purchase price stays lower through its whole life. PVC wins on TCO when exposure is long, UV is intense, or failure is costly β which describes most year-round farm coverings, but not all.
Ask for the UV stabiliser loading or the manufacturer's tested UV exposure hours β a genuine UV-treated product will have a figure. Beware "UV resistant" with no number; on thin film that usually means "lasts a bit longer than untreated," not "lasts a season in the sun."
Yes, and it's a common use. Silage covering benefits from PVC's tear strength and seam integrity under weighting and wind load, and its moisture resistance. Use a food-safe or appropriately specified grade if the covering contacts feed directly, and confirm with your supplier.
PE tarpaulins are typically stitched or heat-sealed along a narrow seam. Under repeated wetting, wind flutter, and UV, the seam is the highest-stress point and the hardest to protect. PVC coated fabrics are usually welded into a continuous bond, which resists that stress far better.
For a structural, year-round farm covering, start at 650gsm PVC and go up for high wind-load or high-consequence applications. Below that, you're trading durability for weight and cost β reasonable for seasonal shielding, risky for permanent coverage.
PVC, generally. PE becomes brittle in freezing conditions and can crack when folded or flexed while cold. PVC coated fabric stays flexible at low temperature, which matters if your covering is folded, stored, and redeployed each season.
Convert both to cost per mΒ² per year over your real lifespan expectation, then add labour for re-covering and a provision for failure cost. Two quotes that differ by 2Γ on the invoice can invert completely once replacement frequency is in the model.
Stop comparing price tags and start comparing cost per season of cover. On most working farms, over a realistic horizon, PVC's higher purchase price buys back more than it costs through fewer replacements, less labour, and fewer failures. But run your own exposure and your own consequence β because the one farm where PE genuinely wins is the one where the covering is brief, sheltered, and cheap to replace.
