Glass or Polycarbonate Construction - Choose Which Best For You

The Victorian Greenhouse line is available with either 4mm Tempered Glass or 10mm Triple Layer "X-Strong" Polycarbonate walls. Each choice has a unique set of advantages allowing you to pick the option which will work best for your needs.

Advantages of Tempered Glass

  • Full transparency is a better "look" for some applications, especially if using the structure for non-plant-growing purposes.
  • The maximum amount of natural light when using the structure for growing plants
  • No fading or discoloration over the lifespan
  • Flame resistant
  • Glass is a chemical-free, environmentally friendly material.

Advantages of Polycarbonate

  • Almost impossible to break, polycarbonate will flex and resist things like objects hitting the panels or heavy wind and snow loads.
  • Blocks harmful UV rays and creates a diffused light environment that promotes consistent light conditions throughout the interior of the structure
  • It has been shown to retain heat more efficiently than glass, an advantage in cold weather growing environments
  • Low maintenance will demand less cleaning than glass while still looking great.

Why Choose a Victorian Greenhouse?

  • UPDATE: Now available with 10mm triple layer "X-Strong" Polycarbonate windows instead of glass. No more need to special order this option.
  • X-Strong polycarbonate panels feature beveled edges with U-shaped metal end caps for increased durability.
  • Aluminum Profiles are larger, thicker, and stronger than those of any competitor in this price range
  • It uses 4mm tempered glass while others use only 3 mm glass
  • Windows are held in place by substantial rubber seals, which provide better insulation - others only use metal clips
  • Vertical glass is only one piece - looks much nicer. Others use two overlapping parts - which fill with dirt
  • 6" high foundation frame included - others usually cost extra
  • 1 or 2 Spindle Roof Window Openers (great in windy conditions), and automatic window openers on other roof windows
  • Includes a misting system (customer has to provide a hose to connect to the faucet)
  • Shoulder (with large gutter) 6'7" high - about 1 foot higher than other greenhouses
  • One sliding door - can be put in any vertical glass location (front, back, or sides)
  • Significantly better insulated than other glass greenhouses. How? Rubber seals, single pane window, and 4mm glass
  • Made in Belgium


  • Uses 4 mm Tempered Glass – others use only 3 mm
  • Available with 10mm triple layer "X-Strong" polycarbonate walls for better insulation in colder climates
  • It uses only single sheets of glass instead of the more common overlapping smaller sections.
  • All glass panes are secured with heavy-duty rubber seals – all the way around – others use only metal clips or flimsy thin rubber strips
  • Using 4 mm single pane glass and heavy rubber seals provide better insulation.
  • Taller design – 1 foot higher – gives you more head space
  • Made with thicker and stronger aluminum profiles – for more strength.
  • TUV & GS tested and approved (similar to a UL listing).
  • Each unit comes with a sliding door that can be put on any side of the greenhouse.
  • Roof windows: come with an old-fashioned spindle and a modern Automatic Window Opener.

      Excellent greenhouse professional quality

      I purchased the vi23 two years ago and could not be more pleased. I have a very small yard would buy the biggest possible otherwise. I am a retired Horticulturist and have owned the double wall polycarbonate and aluminum in past. This product adds beauty and function with lasting quality to your home landscape. The staff were unbelievably helpful and prompt in service. The packaging of the greenhouse was top notch with no problems and the set up was quit basic as well, with the help of my carpenter Before the greenhouse arrived I received a phone call From Andrew Cook to make sure I had all the information I needed and he gave me tips and explanations to help assembly. I have a greenhouse that will last for many years. I live in Memphis Tennessee our zone is a 7b. I have added two small "dairy" type electric heaters , Lights and fan. I added the accessories kit when I purchased. The shade cloth is invaluable here in the mid-south. Yes! I recommend this product.
