About Janssens Greenhouses

Janssens Greenhouse Assembly Overview

What Makes Janssens a Quality Greenhouse Brand

Janssens greenhouses are renowned for their European craftsmanship, superior materials, and long-lasting design. Every detail is built to exceed the standards of most competitors in the same price range, ensuring exceptional performance and visual appeal.

Premium Construction and Materials

  • Heavy-duty aluminum frame: Janssens uses thicker, stronger aluminum profiles than most greenhouse brands, giving each structure superior rigidity and weather resistance.

  • Corrosion-proof hardware: All fittings are made from stainless steel, preventing rust or deterioration in humid or outdoor environments.

High-Performance Glazing

  • 4 mm tempered safety glass: While many greenhouses use 3 mm glass, Janssens provides thicker, TÜV and GS-certified tempered glass for better insulation and durability against wind, hail, and impact.

  • Full-length glass panels: Each glazing sheet is a single, unbroken panel that creates a sleek, modern appearance—unlike the overlapping or segmented panels found on many other brands.

  • Hybrid glazing option: 10mm Twin Wall Heat Block Polycarbonate roof panels. More information and photos here.

  • Weather-tight sealing system: Heavy-duty rubber gaskets hold the glass securely in place, improving insulation and reducing heat loss during colder months.

Smart Design Advantages

  • Integrated foundation frame (4” high): Included with every Janssens greenhouse, providing a stable, level base that other brands often charge extra for.

  • European engineering standards: Janssens greenhouses are precision-built and independently tested for strength, safety, and long-term reliability.

High Quality Product

I just installed the last pane of glass, the one you ordered for me and it’s perfect! The greenhouse is finished and it is beautiful!

My wife and I assembled it on a concrete pad in about 2wks. I’m handy but certainly not a professional builder. The junior orangerie arrived intact with clear instructions. There were videos and the phone help line were available and very helpful. David Kerr, our contact at Exaco was accessible and friendly. His support and advice were very much appreciated.

The Janssen greenhouse is a well engineered high quality product!

We are so glad to have found Exaco Trading co. from whom we purchased it and who assisted us in building it!

I’m am sure it will provide us with many years enjoyment.

I highly recommend Exaco Trading co. and the Janssen products.

Hello, I am interested in the junior orangerie greenhouse. I just tried to order this from home depot website and was told it was out of stock . do you have one in stock? If so how lond does it take to ship and where does it ship from . thanks for your help.

MyGreenhouseStore

Hi WIlliam, Indeed these are now out of stock in the Austin warehouse. We have a pipeline of them on the way from the Janssens factory in Lier, Belgium, where they are manufactured. We've already sold out the shipments that are arriving within the next month. The first container that has some available (4 left at the moment) is expected in Houston Port in early-to-mid September at this point. They will likely sell out again before that container arrives. Would you like to claim one of them? Regards, Steve MyGreenhouseStore.com

My wife is interested in a greenhouse similar to your Junior Orangerie Glass Greenhouse. Will you send me a copy of your installation instructions, and any other info you might have, for review? I need to run it past my HOA and city building permit office to see if they'll even allow it before spending that much money. Thanks in advance for your assistance.

MyGreenhouseStore

Hi Tom, Thank you for stopping by. Here is the link to the installation manual. Feel free to call us at 888-648-5333 to ask any questions you may have. Becky Sher MyGreenhouseStore.com

What is the snow load and wind rating for this structure?

MyGreenhouseStore

Wind Load: 120 mph (3-second gusts), Snow load: 35 PSF (ground-snow load), Roof live load: 20 PSF, per 2017 professional engineering stamp in the State of Texas. If you need a local engineering stamp, we can put your engineering firm in touch with our firm in Texas to get all needed assistance at your expense.

The description indicates it comes with a large bottom frame base. Is this a solid floor or just the frame around the bottom?

MyGreenhouseStore

That is referring to the 4 1/2" aluminum base that goes around the perimeter. It does not include a floor. We do sell some greenhouse flooring material and fabic, and you can also pour a concrete slab, put in pavers, pour gravel on fabric on dirt, put in tiles, or create another flooring system. There are a few things to think about - water drainage, heat retention, comfort, etc.

Can I mount this on a knee wall with the door opening at ground level?

MyGreenhouseStore

Yes! ALL the Juniors now come with an option for mounting on a 15.75” high knee wall or ground mount. All parts are included in the kit.
