Janssens ft Royal Victorian VI 23 Greenhouse Kit - VI-23-GLASS-BLACK

Janssens  ft Royal Victorian VI 23 Greenhouse Kit - VI-23-GLASS-BLACK

This high quality classic Janssens Royal Victorian VI 23 Small Greenhouse Kit provides the optimum environment for gardening year round while adding a delightful stately presence to any backyard setting.

The substantial aluminum framework and full 6ft 7in side wall height give you a comfortable interior workspace. The peak height is 8ft 6in. It has ample room to use as a small greenhouse for your veggies and other plants, or as a sunroom to enjoy the outdoors while you are shielded from the elements.

The Royal Victorian line is available in four sizes. The VI 23 is the small one in the series, at 7ft 9in W x 10ft 2in L x 8ft 6in H. Larger models are the VI 34, VI 36, and VI 46. You have a choice of standard Black or Fir Green aluminum frame. Other colors are available by special order to match your decor. The Janssens Royal Victorian VI 23 Small Greenhouse Kit comes with:

If you choose 4 mm tempered glass you will enjoy a full view of your surroundings and full sunlight entering the greenhouse. This choice offers a traditional beautiful look and crystal clear views with maximum interior light.  With glass side walls, you can choose either a glass roof or a hybrid configuration with the 10mm Heat Block polycarbonate roof.  The hybrid combination gives the best of both worlds - clear views, and good heat protection and insulation on the roof where most light and heat transfer is.

With the 10mm Clearer twin-wall polycarbonate (on the right in the picture) on side walls and roof you will have a lot of light (81% transmission), UV protection (external side of the polycarbonate extrusions), good insulation, and a clear if somewhat distorted view of the outside.  Note that the supply of the full (side walls and roof) clearer polycarbonate VI 23 is limited, and only available while supplies last.  No hybrid version is available with this glazing choice.

With the newer 10mm Heat Block twin-wall polycarbonate roof (on the left in the picture), you will have more diffuse sunlight (58% transmission), a higher level of UV protection (both sides of the polycarbonate extrusions), good insulation, and the panels are more opaque and milky in appearance, offering no clear visibility outside. This choice offers the most heat protection. A full (side walls and roof) Heat Block model is available by custom order. The hybrid model, also a custom order, has glass walls with a Heat Block roof.

Whether you are overwintering special or valuable plants from the cold, starting seedlings, or creating a tropical jungle, you can enjoy years of maintenance-free use. The automatic roof opener, louvered window, and misting system are included to allow you to control the environment within your greenhouse. Optional shade cloth curtains or roller shades are also available if you need more shade in your greenhouse.

The VI 23 is perfect for use as a full featured greenhouse, a cozy jacuzzi house, a sunroom, or an elegant outdoor entertainment space to extend your parties beyond your living room.

Maintenance Tips

• Clean tempered glass panels regularly with a soft cloth and non-abrasive glass cleaner to maintain maximum light transmission.
• Inspect glazing seals, clips, and rubber gaskets periodically to ensure all panels remain secure and weather-tight.
• Remove dirt, algae, and organic buildup from the frame, base, and corners to prevent corrosion and staining.
• Check doors, vents, and windows seasonally and lubricate hinges and moving parts for smooth operation.
• Ensure proper drainage around the greenhouse foundation to prevent water pooling and structural stress.
• Tighten bolts and structural fittings regularly, especially after strong winds or seasonal changes.
• Keep ventilation systems clean and fully functional to maintain stable temperature and humidity levels.
