Janssens | Cathedral Victorian Glass Greenhouse Kit With 4mm Tempered Glass Glazing

The Janssens Cathedral Victorian Glass Greenhouse is a versatile, spacious, feature packed addition to any garden or backyard. The large floor size (15x15, 15x17, 15x20 (baseline), 15x22, 15x25, 15x27, or 15x30), tall sides, and extended roof cupola section allow space for all of your plant growing needs, or use it as a hot tub cover or outdoor sunroom.

Price shown is for the baseline configuration mentioned below (see Features section), and this baseline size and configuration can sometimes have a shorter lead time.

The attractive looks of the Cathedral Greenhouse are matched by superior strength from pre-welded aluminum framing and 4mm tempered glass construction. This choice of glass provides a high degree of safety.

The Janssens Cathedral Glass Greenhouse 15x20 ft baseline configuration includes:

• Four roof vents with spindle openers
• Two louver windows with automatic openers (no electricity required) to help keep the interior at a comfortable temperature
• Two large hanging push out windows on the sides that tilt open for added ventilation
• A wide set of lockable hinged doors for easy access

This is a premium, large size structure that can be used for multiple purposes and will add value to your home.
