Cathedral Greenhouse

The Cathedral is one of our largest greenhouses, distinguished from other Janssens models by a cupola that adds both height and curb appeal. It features a wider footprint than the Royal Victorian line, making for a significantly more floorspace than even the VI 46. Like all Janssens models its 4mm tempered glass and aluminum frame make it resilient enough to withstand wind gusts and most hail. The Cathedral’s structure is additionally reinforced by thick aluminum portal frames which span its entire width, increasing its durability in sustained winds and snow events. Moreover its doors and windows can be installed nearly anywhere, providing substantial flexibility in design.

If you’re searching for a true backyard showstopper that is both beautiful and durable, the Cathedral is the one to pick.

Please note that we keep a limited stock of Cathedral greenhouses on hand, so lead times may be longer than those of other models.

What Makes Janssens a Quality Brand?

  • Aluminum profiles are thicker and stronger than most competitors at an equivalent price range
  • Stainless steel hardware prevents rusting or corrosion of any type
  • Glazing is 4mm tempered glass where many others use 3mm, granting both greater insulation and resilience to extreme weather conditions (wind and hail)
  • Glazing panels are held in place with heavy-duty rubber weather seals
  • Glazing panels are full-sized single pieces, and look much nicer than the overlapping panels sometimes found on other brands
  • 4” high foundation frame is included, where others usually cost extra
  • Tempered glass is TUV and GS tested
