Building and
growing together

For generations to come.

BOAL Systems
Greenhouse roof systems

BOAL Systems provides a comprehensive range of aluminum roof and sidewall systems for high-tech glass or poly greenhouse constructions. 

We have established long-term collaborative relationships with our customer base of regional and global greenhouse builders. Constructed by the greenhouse builders, BOAL has completed over 10,000 hectares of new greenhouses worldwide.

We can tailor our modular systems to include fully integrated solutions such as climate screens, insect netting, insulation and ventilation systems to specific project requirements size, complexity, or regional challenges. 

With a strong focus on partnership, engineering and R&D, BOAL Systems is at the forefront of high-tech covered cultivation with superior technical capabilities and enhanced light transmittance allowing growers optimal yield with minimal resources. 

We continue to innovate to achieve the most ideal growing environment. We are always seeking to identify ways to optimise our current greenhouse systems for more energy-efficient crop cultivation, and we are testing new types of greenhouses systems for special crop-growing circumstances in environments that come with challenging conditions.
- Frank Boers, Managing Director

MODULAR SYSTEMS FOR SEAMLESS INTEGRATION

Product integration goes beyond roof systems.

BOAL Systems ensures that its roofs can be seamlessly integrated into the modular systems supplied by its sister companies Holland Screens, Holland Netting, Alumat Zeeman and WNL:

  • Integrated insect netting
  • Ventilation solutions
  • Climate screen solutions
  • Insulation solutions

PERFECTION, FLEXIBILITY AND AVAILABILITY

We have made a conscious decision to extrude our 100% recyclable aluminum in-house and to produce our greenhouse solutions ourselves. We deliver these to the place where the greenhouse is to be erected in the form of ready-to-use flatpacks.

In-house extrusion of the aluminum profiles by BOAL Extrusion (which is part of the BOAL Group) allows us to easily upscale production and results in a seamless backward integration of the aluminum components.


Teamwork makes the dream work

In this network, we test new ideas and work together to increase knowledge about sustainable greenhouse growing and develop new innovations.

Our partners include the following organisations: 

FROM ORDER TO PRODUCTION AND DELIVERY

Our engineers use state-of-the-art software to calculate the particulars of our clients’ projects and design their greenhouses in 2D and/or 3D. Aluminum profiles are carefully selected using certified calculation methods, on the basis of so-called stress calculations, applicable local standards, crop loads and the specific wishes expressed by the grower and the greenhouse builder. Detailed designs of all the various components are then submitted to our knowledgeable production team. We use high-tech machines to efficiently process the aluminum profiles. Our logistics operations are set up in such a way as to ensure that products are loaded and unloaded safely and efficiently, and at the time of your choosing.

Quality

A recurring theme you will find in all our departments is an ambition to deliver the best possible products. All our processes have been certified to ISO 9001, ISO 14001 and ISO 45001 standards, as well as to CE standards. The certifying organisation, TÜV Nederland, complimented us on the determination and vigor with which we continue to improve our processes, products and working conditions.

Holland netting

Grow greener crops

Holland Netting is a pioneering and leading supplier of insect nettingsystems or integrated pest management (IPM) systems for greenhouse farming anywhere in the world. Insect screens play a crucial part in sustainable crop protection.

They have been found to be effective in keeping out harmful insects, or keeping in useful insects. The insertion of insect netting in roof vents reduces the risk of unwanted insects entering greenhouses.

Holland Netting allows growers anywhere in the world to become less dependent on pesticides or to stop using pesticides altogether, which results in cleaner crops and safe food, grown locally.

Holland Netting’s flyscreens and Holland Screens’ climate screens can be seamlessly integrated into BOAL Systems’ range of aluminum roofing and sidewall systems for high-tech greenhouses made of glass or polymer film.

WNL

Insulation systems

High-quality insulation systems are an essential part of the energy conservation strategy implemented in high-tech greenhouses. By adding insulated sandwich panels to the sidewalls and front walls, which do not require any sunlight, growers will conserve a fair amount of energy. Production and service rooms equipped with insulation panels constitute safe workspaces and storage rooms with a stable atmosphere, thus reducing food wastage.

WNL is the leading supplier of insulation systems to greenhouse builders across the world, with advanced joined panels and integrated systems developed in association with BOAL Systems, such as BOAL S-House™.
