Janssens Modern Greenhouse

A modern clean look is what this mono pitch glass greenhouse was made for. Some people don’t like the classic Victorian style but still want the quality that Janssens delivers for decades. If this sounds like you, Janssens Modern Greenhouse is a perfect choice.

This is one of the few greenhouses that is build as a freestanding greenhouse with a mono pitch roof (it is not meant to be a lean-to greenhouse). The 4mm tempered glass gives it the classic greenhouse look. Thick frame profiles combined with rubber seals and a high-quality structural design will give you peace of mind in any weather condition.

With plenty of roof and louver vents, you won’t have problems getting great airflow going. They all come with automatic openers which don’t require electricity. They simply open and close when the inside temperature rises or falls.
