ProductsIf there have been spectacular developments in greenhouse industry, it is in greenhouse construction. The demand for reliable constructions, with years of carefree cultivation, maximum light transmission and correct insulation has resulted in highly advanced greenhouse constructions.
HAVECON builds such greenhouses. From the first rough sketch up to and including the final completion of the greenhouse, the wishes of the customer come first. HAVECON translates your wishes into a greenhouse that meets all modern cultivation requirements, in any desired size.
The dimensions of the greenhouses that HAVECON builds are listed in the table below. Other variations are of course also possible if the customer so desires.

HAVECON is the leader in greenhouse construction. With a different perspective on building greenhouses. Well-though-out designs, constructed with old-fashioned Dutch thoroughness.
Quality constructions require quality components. Reasons why the HAVECON experienced greenhouse builders use their own specially designed steel and aluminium sections, manufactured to strict quality specifications in our factory.
Because that too is part of HAVECON: Quality down to the last detail.
Correct construction planning, high light transmission, durability and quality are the four concepts which, together with advanced design, set the tone for HAVECON.
HAVECON Kassenbouw works with fixed and reliable suppliers and subcontractors, while Aad Voorwinden (co-owner) has twenty years of hands-on experience as a construction contractor.
HAVECON Kassenbouw has bundled its strengths: development, production, sales, construction, and not forgetting finishing off of the greenhouse, all this takes place and is directed from one central location (and point of contact). HAVECON Kassenbouw is ready for any job!
Aluminium gables and roof constructions come in standard sizes and comply with the strictest requirements and most recent standards specified by TNO (Netherlands Organization for Applied Scientific Research) and insurance companies. The same applies for greenhouse aluminium roof constructions with continuous ridge ventilation, up to 70% opening of the entire roof, suitable for installation of continuous insect screening.
The steel greenhouse components are manufactured with the greatest care and are fully hot-dip galvanized. This guarantees that your greenhouse is built with parts that will last for many years.
To produce a greater light yield, a white powder coating can be applied after galvanizing.
Apart from building greenhouses and industrial buildings, HAVECON also installs heating systems, screening systems (blackout and wall screens), substrate techniques, irrigation systems and total automatic computer control.
If you want to have a greenhouse built that you can rely on. After all, it is a major investment. HAVECON thinks that you are fully entitled to have total confidence in your greenhouse builder. That is what HAVECON is prepared for: a great organisation is the foundation that HAVECON management is built on.
For HAVECON it goes without saying that something that has been agreed on cannot be changed. You will have your greenhouse by the promised date.
