Royal Victorian Hybrid Greenhouse by Janssens — Polycarbonate Roof, Glass Walls
The Royal Victorian Hybrid takes our best-selling Royal Victorian and swaps the roof for 10mm twin-wall polycarbonate, while the walls stay crystal-clear glass. You keep the classic Victorian look at eye level, and gain a roof that holds heat better in winter, cuts heat gain in summer, diffuses harsh midday sun so plants near the peak don't scorch, and stands up better to hail.

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.
-
10mm twin-wall polycarbonate roof — better insulation and hail resistance overhead, and less costly to replace than a glass roof panel.
-
Integrated foundation frame included, where other brands usually charge extra.
-
Full-height single glass panes — no overlapping panels, so it looks cleaner and won't collect dirt.

FAQ
Glass or hybrid — which should I pick?
All-glass gives the clearest view and most classic look. The Hybrid insulates better overhead, softens harsh sun and handles hail better — a great choice for colder or very sunny climates.
Which size is right for me?
VI34 (150 sq. ft.) suits most backyards. VI36 (200 sq. ft.) adds length and a second sliding door. VI46 (250 sq. ft.) adds width for beds down both sides with a center aisle.
What foundation does it need?
A level base such as a concrete strip footing or slab, with the integrated foundation frame anchored to it. We'll help you plan it for your site.
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.
