Frequently Asked Questions
It depends on the size of the greenhouse. But generally, it takes about two people a weekend. It is recommended to be two people when assembling the house. See the assembly guide here.

The substrate must be level. Assemble the base and place the embedment brackets in holes or pipes in the ground. The base must be levelled and cross measurements checked. The base is then poured with concrete. Check the cross measurements and that it is level after the concrete has been poured. See installation guide for bases here .
It's important that a greenhouse sits on a strong and stable base that is firmly anchored in the ground. Some insurance companies only cover storm damage if the greenhouse is mounted on a moulded base. We recommend that you talk to your insurance company about setting up a base and greenhouse to ensure that you are properly insured in the event of storm damage.
You can choose to make a fully cast concrete base, which is very demanding. You can also make a base out of safety-impregnated wood. We always recommend buying an original Juliana base, which consists of precisely cut 12 cm high galvanised steel profiles that are easily assembled over the supplied cast iron.
This ensures adequate bases and is an easy-to-use solution.
Yes, you can. Many customers place the greenhouse on a terrace. You need a base and then cut off the moulding brackets. Then screw the base frame to the ground. However, Juliana does not take responsibility for faults and defects when the construction is changed. Check with your insurance to see if it covers when the house is not cast in place.

When investing in a greenhouse, it's important to consider your needs. If it's the first time you're buying a greenhouse, it can be difficult to assess your own needs, and in that case, the best advice we can give is to buy it as big as the garden allows. We've never had a customer complain that they bought a greenhouse that was too big.
That's not to say that you don't get a lot of pleasure from a smaller greenhouse, because you certainly do. It just means that you'll often get caught up in the joy of growing and wish you had room for much more.
Juliana's greenhouse models all have good side and overall height, which is important because it provides space and room for people and plants. It's nice to make room for a chair and a small table in your "oasis" where you can enjoy your coffee and newspaper. Even in the very early spring, it doesn't take much sun to provide warmth and light, and it's a great place to sit.
There's no clear-cut answer to this question, but again, it's good to start from the way you want to use your greenhouse. If you think of the greenhouse solely as a place to optimise cultivation, then you may benefit from some of the advice below. If you also want to enjoy your greenhouse as a "driver's house", it's a good idea to have it close to your terrace or the place in the garden where you spend the most time. This way, the greenhouse becomes a natural part of your daily life and you'll get the most out of it.
The N-S or E-W location depends on several things. For example, how early in the year you want to start, do you have glass or polycarbonate, and what plants are you growing. The following guidelines are for guidance only, as there are probably as many opinions on this topic as there are gardeners, but they are very good guidelines for first-time buyers.
The N-S orientation is optimal if you have a glass greenhouse. When the sun rises in the east, the greenhouse heats up quickly, and when the midday sun is in the south, the narrowest side faces the sun, so it doesn't get as hot. When the sun sets in the west, the greenhouse utilises the sun's heat to the fullest.
The E-W orientation is optimal for those who want to get an early start in the spring and for those who have chosen a greenhouse with polycarbonate sheets. In early spring, most light comes from the SE to SW, and with the wide side of the greenhouse facing south, you get the most light to your plants. This is especially important for polycarbonate greenhouses, as it allows them to extend the season even further than if they were facing N-S.
TIP: MAKE SURE YOU'RE SHELTERED
The wind cools the greenhouse, so make sure there is shelter around the greenhouse with a hedge or fence so the wind can't cool it down as much. Also, be careful not to place the greenhouse too close to large trees. They shade the greenhouse and falling branches can damage glass and profiles.
When choosing a cladding/glass type for your greenhouse, there are basically two options: clear glass or non-transparent polycarbonate.
Polycarbonate has the advantage of insulating due to the air in the ducts, which protects against frost at the beginning and end of the season. Polycarbonate also refracts light, minimising the need for a shading solution. For most Juliana models, polycarbonate is available in 6 and 10 mm thicknesses.
Glass is by far the most commonly used covering material today, primarily for aesthetic reasons. Glass is available either as traditional split greenhouse glass or as toughened glass in full lengths. The latter is by far the most attractive and provides a solution that is much stronger than regular glass. In addition, in the event of an accident, toughened glass shatters into very small pieces, whereas regular glass breaks into large pieces with a higher risk of cutting yourself. Watch a video about the difference between the glass types here:
Juliana Drivhuse A/S gives a 12 year warranty on its greenhouses, excluding glass and polycarbonate.
For more information on what the warranty covers, please refer to the assembly guide for the greenhouse in question.
It is difficult to protect yourself 100% against storm-force or hurricane-force winds.
The best way is to choose a strategic position for your greenhouse in advance. Preferably sheltered by other buildings, trees or garden structures that can help to ‘break’ the direction of the wind and create ‘blind angles’ where the wind does not directly blast the greenhouse.
We have found that, beyond a shadow of a doubt, the biggest factor in how well the greenhouse can weather a storm is its position. That applies no matter what model of greenhouse you have.
All Juliana greenhouses are produced at the factory in Odense, Denmark.
In the event of storm damage to your Juliana greenhouse, we recommend that you first contact your insurance company for an estimate of the damage and to clarify any conditions of cover.
Then get in touch with your Juliana wholesaler or dealer who will be able to help you replace your greenhouse. You can find our retailers here.

If you need glazing for your greenhouse, you can order it and have it cut to size by your local glazier. Alternatively get in touch with a Juliana wholesaler or dealer who will be able to help you. You can find our retailers here.
All three automatic window openers fit all greenhouses with glass (except for Juliana City Greenhouse). If you have a greenhouse with polycarbonate, we recommend using the Univent window opener, as it has double springs. Spiro and Ventomax are not recommended for windows with polycarbonate.
Your opener can be installed in your greenhouse all year round. However, you should make sure that the cylinder of your opener is removed during the winter period to protect it. As spring approaches, it is recommended to lubricate all moving parts with some thin oil (olive oil). Also, lubricate the threads with grease or Vaseline before reinstalling the cylinder.
You can order automatic window openers from a Juliana wholesaler or dealer.
As the goods are being delivered it is important to check for damage in transit and make sure the number of collis matches your delivery note.
Any damage in transit or missing parts must be reported to your wholesaler or dealer as soon as possible.
