Are you looking for a large but elegant greenhouse? The Royal Victorian VI46 Greenhouse provides plenty of space for plants as well as lounging. The first-class greenhouse adds old fashioned style and beauty to your backyard. This is a classic English greenhouse with the best insulation and features of modern technology. The TUV and GS testing provide peace of mind and create a safe operating environment.
The Janssens Royal Victorian VI46 features seamless vertical panels in 4mm tempered glass or 10mm twin-wall Polycarbonate. No seams prevents potential air leaks and collection of dirt. Panes are secured with heavy-duty rubber seals without the use of metal clips. This, combined with seamless panels, creates better insulation all the way around.
The automatic roof openers, built-in misting system, and interior shade cloth allow you to control the environment to your specific needs. Whether you are overwintering valuable plants, starting seedlings, or creating a tropical jungle, you can enjoy years of use with this high-quality greenhouse kit.
Glass or Polycarbonate – Which glazing option should you pick for your Janssens Royal Victorian VI46 Greenhouse?
The choice between glass and Polycarbonate is an important one because they will serve different purposes. It basically comes down to your priorities:
- Are you buying the greenhouse for the aesthetic appeal? Then you should pick glass.
- Do you care more about practicality and the best growing environment? Go with Polycarbonate.
Clear glass panels look better and they give you the old-fashion greenhouse feeling. However, they don’t break the sunrays which means that your glass greenhouse will be hotter than a Polycarbonate greenhouse. This will play a huge role if you live in a hotter climate. Polycarbonate provides more insulation and durability but it’s not as elegant as glass because it isn’t transparent.
This is just a short summary to show you the major differences. We have written a very thorough article about choosing between glass or Polycarbonate here.

Janssens – 75 Years of Experience
Janssens is a Belgian manufacturing company that specializes in high-end greenhouses, orangeries, and more. They are market leaders in Europe and in the USA. Their elegant glass greenhouses stand out because of their high-quality design and innovation.
Does it need a concrete foundation?
All Janssens greenhouses require proper footing because of the included foundation frame. We don’t recommend complete concrete slabs because they hold a lot of heat in the summer and a lot of cold in the winter. A glass greenhouse already heats up and cools down very easily. A footer filled with gravel, dirt, or pea rock in the middle is a better option.
You have to cement the foundation into the footer for the perfect stability. Do not set concrete in the corners until the entire greenhouse frame is complete, level, and square! Please, have a look at the manual or this assembly video for the Royal Victorians. They illustrate how it’s done correctly.
Can I put the Royal Victorians on a stem wall?
Yes, you can purchase a drop door kit so that you can install the greenhouse on a 10-40” high stem wall. Please note, the kit does not include the glass that goes on top of the door. You can purchase this piece locally to suit your desired height.
Is it possible/wise to remove the rain gutters, say during the winter months?
No, the gutters are part of the aluminum extrusion.
Should we choose glass or Polycarbonate?
The choice between glass and Polycarbonate is an important one because they will serve different purposes. To keep it short: Glass is purely for aesthetics and Polycarbonate for functionality. You’ll have more protection from the weather and a better growing environment with Polycarbonate. It doesn’t look as nice as glass, though.
Benefits & disadvantages of glass:
- Great aesthetics
- Fragile, may break
- Panes do not fade or scratch easily
- Allows most light, doesn’t break light (not a good thing in hot climates)
- Less insulating
- Heavy panels are difficult to handle
- Easier and less expensive to find a replacement if needed
- Harder to keep clean/clear (hard water, they will fog with humid climate inside the greenhouse)
Benefits & disadvantages of Polycarbonate:
- Less visually pleasing
- Sturdy, less likely to break
- Panes may scratch and fade a little
- Light breaks (no hot spots)
- More insulating
- Lighter panels are easier to handle
- May take longer to replace
- More expensive to replace
Glass has historically been used for greenhouses and has the best aesthetic appeal. It also lets in the most light without breaking it. The panes do not fade over time and are easy to replace. However, the panes can be heavier to work with, may break, have less insulation, and require more maintenance to keep clean.
Advances over the years have made Polycarbonate an additional option worth considering. Polycarbonate has better light diffusion, is more resistant to changes in weather, and resists cracking. It is not as beautiful as glass, scratches more easily, and can be expensive to replace (in the case of breakage).

What is the difference between a Royal Victorian and Junior Victorian greenhouse?
Junior Victorians are overall shorter and come in smaller sizes. When you compare the dimensions of the J-VIC 23 and VI 23, you’ll see that the center height is shorter. Also, the shoulder is significantly lower 5ft 2in on the J-VIC 23, versus 6ft 7in on the VI 23.
What is the difference between a Royal and Retro Victorian greenhouse?
The Royal Victorians have complete glass panels. The Retro Victorian utilizes narrower 14″ vertical panels of 4mm tempered glass with decorative non-glass panels for the lower sections. This creates a totally different look and might be an advantage in some weather situations.
What is the difference between the Junior Victorian Orangerie and Royal Victorian Orangerie?
These two orangeries look very similar but they are not identical. In case you are unsure which one to pick, we want to make it easier for you:
|Junior Victorian Orangerie||Royal Victorian Orangerie|
|Peak height||8ft 2in||9ft|
|Shoulder height||5ft 2in||6ft 7in|
|Size||10ft 3in x 13ft||12ft 10in x 15ft 6in|
|Glazing||Glass||Glass or Polycarbonate|
|Door||Single sliding||Double sliding|
The most significant differences in these two models are size and features. The Junior Victorian Orangerie is smaller overall than the Royal Victorian Orangerie. The Junior Victorian Orangerie has a shorter peak and shorter shoulder height than the Royal Victorian Orangerie. The Junior Victorian Orangerie is also shorter in length than the Royal Victorian Orangerie, with a smaller overall growing area and footprint. The Royal Victorian Orangerie has more features such as the choice of Glass or Polycarbonate, and more roof/Louver vents.

What is TUV & GS testing?
Products bearing the GS mark have been subjected to rigorous testing and evaluation. TUV & GS is German testing similar to UL Independent Testing and Certification in the United States. It is voluntary testing and certification that means a sampling of the product has been tested for safety and found to meet the minimum requirements of the German Equipment and Product Safety Act.
Accessories and add-ons
What heater would you recommend?
This highly depends on the size of the greenhouse. We offer some heaters here and guide you through picking the right heater here.
Do you sell an extra sliding door?
The Janssens Royal Victorian Single Sliding Door can be added at the back or side of your greenhouse. This way you can create two entrances. You can find the product here.
Janssens VI 34
Does the VI 34 come with a hinged double door?
No, it has a single sliding door. You can order a hinged double door if you desire one. Call or email for pricing.
Janssens VI 46
Is VI 46 a kit with instructions that a reasonably skilled craftsman and another person can assemble?
You can have a look at the manual and resources here and judge for yourself. If you feel it’s too complicated or you don’t have anyone who can help you, we recommend professional installation. You can hire a local contractor for the job. Installation can also be discussed with Exaco (the importer), especially if you are in Texas. You can reach them at (512) 407-8500. You should use Ext 701 to talk to Claudia and she can get the prices.
Where can I find a pdf of the assembly instructions for the Royal Victorian Orangerie?
You can find the assembly instructions (including the foundation information) on our manuals page.
Is the EOS Junior T Orangerie 10 ft front to back and 13 feet left to right as you stand at the front entry?
From the door to the back is 3189mm, which is roughly 10.46ft and the 13ft is indeed left to right as you stand at the front entry. Check Page 9 of the manual for more details.
Where does this ship from?
Do you deliver to the house?
This product is delivered via LTL which is curbside delivery only. You will need to work with the driver to unload the contents of the crate, leaving the crate on the truck. The exception would be if you have a forklift or tractor with long forks available, which can be used with the liftgate to lower the entire crate to the ground. We recommend having a couple of people there for the delivery. The VI 36 and VI 46 are particularly heavy.
How long does it typically take for the shipment to arrive?
It usually takes about 2 weeks for your order to arrive. This unit ships from Texas. It takes 1-2 business days to package and then it ships to the shipping facility located nearest to you. The shipper then makes contact to schedule a delivery.
Due to the high demand during this pandemic, we are running low on products, and shipping companies take longer than usual. Please, keep this in mind when ordering. We will send you a follow-up email if there is a longer waiting time for your order.
