  • Why Janssens®?

Janssens® Victorian greenhouse aluminum profiles are larger, thicker, stronger than those of any competiter in this price range. The 4mm glass that Victorian used is better than other brands 3mm. You also can choose from glass or polycarbonate glacing. 

  • Can I customised Janssens greenhouses in your store?

Yes. Please contact us for customise your owe Janssens greenhouse ideas. The lead time will be 5-6 months.

  • Glass or Poly?

GLASS: Traditional horticultural glass (3 to 4 mm thick) is most often used in greenhouses because it is cheaper than safety glass. However, it is less strong and when it breaks it shatters into sharp pieces. Safety glass is five to seven times stronger than horticultural glass and should it break in an extreme case, it will fall apart into small harmless pieces. All our conservatories are equipped with 4mm safety glass as standard.

POLYCARBONATE: If you want to completely prevent glass breakage and also want to pay attention to insulation, you can also opt for plastic windows. These consist of clear double sheets of polycarbonate. They insulate 40% better than single glass, which means less temperature fluctuations occur in the conservatory. An additional advantage of plastic is that the sun's rays are effectively filtered.
