    FAQ's

    Janssen Greenhouses do require a foundation but it does not need to be a fully concrete slab foundation. 

    Foundations don’t need to be concrete although it is an effective and durable foundation option.

    If gutters come with the Janssen greenhouse they are attached to the aluminum frame. This means you can’t remove the gutters.

    Junior Victorians are overall shorter and come in smaller sizes. When you compare the dimensions of the J-VIC 23 and VI 23, you’ll see that the center height is shorter. Also, the shoulder is significantly lower 5ft 2in on the J-VIC 23, versus 6ft 7in on the VI 23.

    The Royal Victorians have complete glass panels. The Retro Victorian utilizes narrower 14″ vertical panels of 4mm tempered glass with decorative non-glass panels for the lower sections. This creates a totally different look and might be an advantage in some weather situations.

    Products bearing the GS mark have been subjected to rigorous testing and evaluation. TUV & GS is German testing similar to UL Independent Testing and Certification in the United States. It is voluntary testing and certification that means a sampling of the product has been tested for safety and found to meet the minimum requirements of the German Equipment and Product Safety Act.

    Yes, you can purchase a drop door kit so that you can install the greenhouse on a 10-40” high stem wall. Please note, the kit does not include the glass that goes on top of the door. You can purchase this piece locally to suit your desired height.

    Is it possible/wise to remove the rain gutters, say during the winter months?

    No, the gutters are part of the aluminum extrusion.

    Yes, you can install the door on either greenhouse end wall.

    The Janssen Greenhouse can be used year-round, there are several factors to consider. The two main factors are weather and plants.

    What are the plants you want to grow and how much heat or cold can they handle? No matter where you live, greenhouses can be 20-40 degrees hotter inside during the day and at night they will be the same temperature as the outdoors. This is without any supplemental heating or cooling.

    Depending on where you live, heating and/or cooling your greenhouse can make the difference.
