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.
