Exaco Janssens Cathedral Victorian Orangerie Greenhouse 15ft x 20ft
The Janssens Cathedral Victorian Greenhouse is a versatile, spacious, feature packed addition to any garden or backyard. The 20 by 15 foot floor size, 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 sun room.
The attractive looks of the Cathedral Greenhouse are matched by superior strength of pre-welded aluminum framing and 4mm tempered glass construction. This choice of glass provides a high degree of safety and impressive insulative value.
The Cathedral Greenhouse includes four roof vents with automatic openers and a louver window to help keep the interior at a comfortable temperature. Two hanging windows on the sides can also swing up for added ventilation. A set of lockable swinging doors and a single lockable sliding door make entry simple.
Additional features include four roof vents with automatic openers, and a Louvre window which can be used together for enhanced temperature control.

How delivery works
-
1
You place your order
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
-
2
We call to schedule
We'll contact you to set up a delivery time frame that works for you.
-
3
Free curbside freight
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.

Receive and unload
Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.
Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.

Frequently asked questions
Can't find your answer? Our greenhouse specialists are happy to help you choose.
678-408-8222 Email usDo I need a building permit for the Cathedral?
Because of its size, we recommend checking your local building code for any required permits before you order. The Cathedral structural permit set and the wind and snow load certification are in the documents section to help with that.
How tall is it inside?
The first gutter is 6' 8" high and the first ridge is 9' 1". The raised cupola section has a second gutter at 10' 9" and a top ridge at 12' 2".
Can I use it as something other than a greenhouse?
Yes. With 298 sq ft of floor space, tall sides and the extended cupola roof, it works well as a sunroom or as a cover for a hot tub, as well as a place to grow.
How is it ventilated?
Four roof windows and a louvre window work together for temperature control, and two large side windows hang from the top and swing upward for extra airflow.
What doors does it have?
It has a wide, lockable set of double hinged doors with closers, plus a single lockable sliding door, so you have two ways in.
What frame colors are available?
You can choose a black or a bronze aluminum frame using the color option above.
Is shipping really free?
Yes. Shipping is free. Locations with limited access, such as islands, are rare exceptions that may carry an extra fee, and we'll tell you before anything ships.
Do you offer a price match?
Yes. If you find the same greenhouse for less from an authorized dealer, call or email us with the offer and we'll review it.
Are you an authorized retailer?
Yes. Mulberry Greenhouses is an authorized retailer, so your greenhouse is covered by the full manufacturer warranty.
