Royal EOS T Greenhouse by Janssens — T-Shaped, Narrow-Pane Glass
The Royal EOS T brings the T-shaped Orangerie layout to full Royal-line proportions — 169 sq. ft. with a double-hinged, full-length glass door entry, and the narrow, vintage-style panes Janssens is known for. It sits between the compact Junior Orangerie and the larger Royal Antique Orangerie.
Available in White or Black. This is a special-order model through Janssens, so lead times run longer than our stock greenhouses — call or text us for a current estimate.

Built for Strength
-
Heavy-duty 17-gauge tubular aluminum frame — larger, thicker and stronger profiles than most greenhouses in its price range.
-
4mm tempered safety glass (where many brands use 3mm), TUV and GS tested for resilience to wind and hail.
-
Heavy-duty rubber seals hold every pane in place all the way around, for a tight, better-insulated structure.
-
Stainless steel hardware that won't rust or corrode.
- Engineered for winds up to 120 mph and a 25 PSF ground snow load.
-
38° roof pitch sheds snow quickly.
-
Full-height single glass panes — no overlapping panels, so it looks cleaner and won't collect dirt.

FAQ
How does it compare with the other T-shaped models?
All share the T-shaped foyer layout at different scales: Junior Orangerie 116 sq. ft., Royal EOS T 169 sq. ft., and Royal Antique Orangerie 185 sq. ft.
Why is it special order?
Janssens builds it to order rather than stocking it. Same frame, glass and 15-year warranty — just a longer lead time.
What foundation does it need?
It's designed for a knee (stem) wall, with two sidewall-height options depending on the wall. Talk to us before you pour so the foundation matches your configuration.
Does it come with shelving or misting?
Not standard — both are available as accessories, and we'll package them for your project.
Do I need a permit?
Often, since this is a permanent structure on a foundation — requirements vary by town, so check with your local building department before you order.
