When you’re investing in a commercial greenhouse, the covering material isn’t just a surface decision—it determines how long your structure lasts, how well your crops grow, and how much you’ll spend on maintenance and replacement over the years.
So which greenhouse covering material truly lasts the longest? Let’s explore the three most widely used materials—polyethylene film, polycarbonate panels, and glass—to determine which is the most durable for your farming operation.
Polyethylene (PE) film is a flexible plastic used in single or double layers for greenhouses. It’s lightweight and economical, making it a go-to choice for budget-conscious growers.
Single-layer PE: ~2 years
Double-layer PE (with UV treatment): 3–5 years
Some premium multilayer films with anti-drip and IR features may last up to 6 years with proper care.
Needs regular inspection for tears and UV degradation.
Can be replaced easily, but frequent replacement adds long-term costs.
Lowest initial cost among all options.
Best for short-term projects or seasonal growers.
Higher long-term cost due to frequent replacement.
Farmers in mild climates or who operate seasonally.
Startups looking for a low upfront investment.
Polycarbonate is a rigid thermoplastic available in twin-wall and multi-wall designs, offering insulation and impact resistance. It’s increasingly popular for mid- to large-scale greenhouses.
UV-protected panels: 10–15 years
Premium multi-wall panels may last 15–20 years with little deterioration.
Minimal maintenance required.
Occasional cleaning and UV inspection recommended.
Resistant to hail and physical damage.
Moderate upfront cost, but excellent long-term ROI.
Ideal for growers seeking a long-lasting, lower-maintenance solution.
Commercial farms in windy, cold, or variable climates.
Growers focused on year-round production.
Tempered or horticultural glass has been used for centuries. It offers unmatched light transmission and a sleek appearance, often used in high-end or institutional greenhouses.
Tempered glass: 30–50 years with proper installation
Requires sturdy framing (typically aluminum or steel)
Breakage possible under impact (hail, storm debris)
Regular cleaning is needed to maintain clarity.
Frames and seals may need repair over time.
Highest upfront cost of all materials.
Excellent for long-term investment—especially if structure longevity is the top priority.
Permanent installations in temperate climates.
Educational, botanical, or high-value crop facilities.
| Covering Material | Average Lifespan | Maintenance Level | Initial Cost | Long-Term ROI |
|---|---|---|---|---|
| Polyethylene Film | 2–6 years | High | Low | Low–Moderate |
| Polycarbonate | 10–20 years | Low | Medium | High |
| Glass | 30–50 years | Medium | High | Very High |
Durability isn’t just about the material—it’s also about the climate you’re growing in:
Hot/dry areas: UV degradation is a concern—choose UV-stabilized polycarbonate or glass.
Cold/snowy regions: Polycarbonate resists cracking and provides insulation.
Storm-prone zones: Avoid glass unless protected; opt for impact-resistant polycarbonate.
If lifespan alone is your priority, glass is the winner, lasting up to 50 years. But if you factor in durability, maintenance, and cost, polycarbonate panels strike the best balance for most commercial growers. Polyethylene film remains a solid short-term option but requires regular replacement.
For most commercial applications, UV-protected multi-wall polycarbonate provides the best durability-to-cost ratio—especially for growers operating year-round.
