Sooner or later an investor in the greenhouse business faces a specific question: build a Venlo glass complex or settle for an industrial film greenhouse? Both structures are designed for areas from 1,000 m² and year-round operation, and both come with climate control and irrigation systems. But their capital investment, launch times and operating economics are fundamentally different.
In this article we look at how a Venlo greenhouse differs from an industrial film greenhouse in structure, cost of ownership and use cases. Without categorical conclusions — the choice always depends on the crop, the region, the area and the budget of the particular project.
The fundamental difference between Venlo and an industrial film greenhouse
The two formats solve the same task — creating a controlled environment for commercial growing. The differences begin at the level of the structure and the covering and then diverge in the cost of entry, the engineering complexity and the planning horizon.
How a Venlo greenhouse is built
Venlo is an industrial glass greenhouse developed in the Netherlands that has become the world standard for high-intensity production. The structure consists of repeating gable sections 3.2–4.8 metres wide glazed with 4 mm toughened glass. The load-bearing frame is made of galvanised steel profile.
Light transmission of 88–92% is retained throughout the service life of the covering — 25 years and more. The modular structure allows the area to be extended to dozens of hectares. Climate control, fertigation, supplementary lighting and screening are run by a single automated system.
Capital investment in a Venlo is considerably higher than in a film equivalent. The reinforced frame, the complex engineering and the longer installation create an entry threshold that is justified over a long horizon.
How an industrial film greenhouse is built
An industrial film greenhouse is a multi-span structure with a galvanised profile frame and a covering of light-stabilised film. The span width is from 8 to 12 metres. The gothic roof shape lets precipitation run off naturally and increases the internal volume.
Ventilation is provided by roll-up side walls and ridge vents. Some configurations use an inflation system — air is blown between two layers of film, which improves thermal insulation and reduces heating costs in winter.
The film covering lasts 3–5 years and is replaced without dismantling the frame. This creates regular operating costs, but the initial investment in a film complex is 2–3 times lower than in a Venlo of comparable area. Installation takes less time, and the modular principle allows the area to be brought into use in stages.
When it makes more sense to build a Venlo
A Venlo glass greenhouse is not economically justified in every project. There are several scenarios in which the high capital investment pays off over a long horizon.
Large projects of 3–5 hectares and above. At this scale the difference in unit cost between Venlo and a film greenhouse narrows, and the advantages of stable light transmission and minimal maintenance of the covering come into their own.
Light-demanding crops with high added value. Trellised tomatoes, cut roses, chrysanthemums — where every percentage point of light directly affects yield and product quality. Unlike film and polycarbonate, glass does not cloud over time and provides a stable light flow for decades.
Regions with access to agricultural subsidies. Federal and regional support programmes for greenhouse construction can cover a substantial part of the capital costs, which noticeably shortens the payback period of a Venlo.
A long-term strategy of 10–15 years. Over such a horizon the total cost of ownership of a Venlo can turn out to be comparable with a film greenhouse, because there are no regular costs for replacing the covering.
When an industrial film greenhouse is the more rational choice
An industrial film greenhouse suits a wider range of tasks and budgets. Here are the typical situations in which this format is preferable.
A limited starting budget. For family farms and medium-sized businesses entering the greenhouse sector, a film structure makes it possible to start production and begin earning revenue at significantly lower initial cost.
Phased expansion. New spans are added to an existing complex without stopping production. A business starts with 1,000–2,000 m² and increases the area as demand grows, spreading the investment over time.
Fast commissioning. A one-hectare film greenhouse is handed over in 3–5 months, a Venlo in 6–10. When the planting date has to be met, a film structure gives a head start.
Seasonal and extended-season growing. For businesses that work from spring to autumn the high capital cost of a Venlo may not pay off. A film greenhouse handles seasonal production at a reasonable investment.
Venlo versus film greenhouse: comparison by key parameters
| Parameter | Venlo greenhouse | Industrial film greenhouse |
| Covering | 4 mm toughened glass | Light-stabilised film |
| Light transmission | 88–92%, stable | 85–92%, falls towards the end of the service life |
| Service life of the covering | 25+ years | 3–5 years (replaced without dismantling the frame) |
| Capital investment | High | Moderate (2–3 times lower than Venlo) |
| Operating costs for the covering | Minimal | Regular replacement of the film |
| Heating costs | Lower (air tightness, screens) | Higher (heat losses through the film) |
| Installation time (1 ha) | 6–10 months | 3–5 months |
| Level of automation | High (comprehensive automation) | Medium to high (depends on the package) |
| Roof shape | Gable (Venlo standard) | Gothic or arched |
| Ventilation | Ridge vents, side vents | Roll-up sides, ridge vents, inflation |
| Scalability | Modular, no limits | Modular, no limits |
| Indicative payback | 5–8 years (depends on the project) | 2–4 years (depends on the project) |
| Best scenario | Large intensive complexes, supplemented lighting | Family farms, phased growth, seasonal and year-round production |
Any comparison is only valid within a particular project — the exact figures depend on the area, the region, the crop and the composition of the engineering systems.
Which questions to answer before choosing a project
Before comparing proposals for a Venlo and a film greenhouse it is worth answering a few questions. They determine which format suits your business.
| Question | Why it matters | How it affects the choice |
| Which crop do you plan to grow? | Requirements for light, height and microclimate differ | Light-demanding crops (tomatoes, roses) argue for Venlo; less demanding ones (leafy greens, seedlings) are handled by a film greenhouse |
| What is the area of the complex? | The unit cost of Venlo falls as the area grows | Up to 1–2 ha a film greenhouse is usually more economical; from 3–5 ha the difference narrows |
| Year-round or seasonal production? | It determines the requirements for heating and covering | Intensive year-round — Venlo is more efficient; seasonal — a film greenhouse is more rational |
| What is the starting budget? | The difference in capital costs is substantial | A limited budget — film; access to subsidies or long-term finance — Venlo |
| Which region will it be built in? | Snow and wind loads, the cost of energy | Both structures can be adapted, but the cost of adaptation differs |
| What horizon are you planning for? | The total cost of ownership changes over the years | Up to 5–7 years a film greenhouse is cheaper overall; from 10–15 years Venlo starts to win |
The answers to these questions allow a contractor to propose not an abstract solution but a configuration for specific tasks.

FAQ
Which is cheaper to build — a Venlo or a film greenhouse?
An industrial film greenhouse requires lower capital investment at the start — 2–3 times lower for a comparable area. Over a horizon of 15–20 years, however, the total cost of ownership may converge because of the regular replacement of the film.
Which pays back faster?
The indicative payback period of a film greenhouse is 2–4 years, of a Venlo 5–8 years. The exact figures depend on the crop, the region, the scale and access to subsidies. The calculation is always individual.
Which greenhouse should be chosen for tomatoes?
Both options suit commercial growing of trellised tomatoes. For intensive year-round production on areas from 3 ha a Venlo gives an advantage in light level and microclimate stability. For seasonal growing and areas up to 2–3 ha a film greenhouse does the job at a lower investment.
Which is better for berries?
Berries — strawberries, raspberries, blackberries — are grown successfully in both types of greenhouse. In practice most berry growers choose film structures or high tunnels, since berries are less demanding of light transmission and the lower entry threshold allows them to reach profitability sooner.
Can a film greenhouse be upgraded to the level of a Venlo?
No — these are fundamentally different structures. A film greenhouse can, however, be fitted with supplementary lighting, climate control and automation, bringing the level of microclimate control closer to that of a glass equivalent.
Are both options suitable for the Russian climate?
Yes. Both structures are adapted to the snow and wind loads of the particular region of construction. The frame is reinforced, the heating system is designed with a capacity reserve, and film greenhouses are additionally fitted with an inflation system to improve thermal insulation.
What is the minimum area for each type?
For both options commercial construction makes sense from 1,000 m². The economic advantages of a Venlo begin to show at areas from 3–5 ha.
How can a cost estimate be obtained?
Send a request on the NIVA GREENTECH website. A manager will clarify the area, the crop and the region and prepare an individual budget with equipment options for both types of structure.
