High-quality aluminium profiles

As greenhouse manufacturers, we develop our own high-quality aluminium profile systems that precisely meet the highest requirements. Our range now includes approximately 450 of our own profile cross-sections. The ridge, gutter, and base profiles are particularly important for stability. All load-bearing profiles are continuous, preventing weak points (leakage).

Glazing with real glass

Glazing with real glass possible

Our high-quality profile systems have a high roof load capacity of up to 150 kg/m². Therefore, we can equip the Bio-Top series with 16 mm thick insulated glass in the roof area – for optimal light utilization and increased durability. Of course, we can also provide other types of glazing upon request.

Bio Varis with sliding door

Large selection of doors

By default, the Bio-Varis features sliding doors. However, depending on preference, a split hinged door can be chosen. A so-called horse stable door can remain closed in the lower part to prevent pests from entering, while the upper part enhances natural ventilation. An undivided hinged door is also possible, of course.

Assembly of the side wall in the greenhouse without glazing

Well thought out

All Hoklartherm greenhouses feature a modular system, making them easy to assemble using a step-by-step process. Windows and doors are pre-installed. To ensure everything goes smoothly, all products undergo a rigorous quality control before delivery.

To ensure that the greenhouse remains an eye-catcher in the garden for many years to come, our greenhouses are standardly powder-coated in RAL 6009 fir green. Other colours are also available upon request.

Besides size, the material plays a crucial role in greenhouses. Specially developed aluminium profiles provide high load-bearing capacity – a crucial factor when it comes to safety and durability in many greenhouses. Upon request, we gladly customize our products to your preferences. For instance, you can opt for ISO safety glass: not only does this real glass meet the highest aesthetic demands, but it is also exceptionally stable and sustainable.

Cozily furnished Bio-Varis greenhouse


The Bio-Varis greenhouse from Hoklartherm offers optimal possibilities for overwintering large plants or ambitious gardeners. The structure can also be used as a dining room in the open air or as a photo studio in the middle of the forest. With accessories, you can give your glass greenhouse a personal touch. Turn your greenhouse into an oasis of well-being or a place of tranquillity. We are happy to advise you on implementation and always enjoy receiving pictures from happy greenhouse enthusiasts.
