How to Choose a Winter Greenhouse


The design or type of a greenhouse is crucial, especially for winter use. Traditional designs like the Janssens Royal Victorian offer a classic look and effective heat retention, while innovative designs like the Hoklartherm Riga’s “onion” shape are engineered for snow resistance and wind deflection.

Dome or geodesic greenhouses can also be effective in winter, as their shape allows for even distribution of snow and wind loads. When choosing a design, consider not just the aesthetic appeal but also how the shape will interact with your specific winter conditions.


Size is a significant factor in choosing a winter greenhouse. Larger greenhouses, like the Janssens Royal Victorian VI46, offer more space for a variety of plants and can create a more stable internal environment.

However, they also require more heating in colder months. Smaller greenhouses, on the other hand, are easier to heat and may be sufficient for your winter gardening needs.

Consider the space available in your garden and the scale of your winter gardening plans when deciding on the size.


Durability is paramount in a winter greenhouse. Look for structures with strong frames made from materials like aluminum or galvanized steel, as seen in the Exaco Livingten and Hoklartherm models.

The glazing material is also crucial; polycarbonate panels offer more durability and insulation compared to traditional glass. Ensure that the greenhouse can withstand heavy snow loads and high winds, common in winter months.


The frame of your greenhouse should be robust enough to withstand winter conditions. Aluminum frames, like those in the Janssens and Hoklartherm greenhouses, are rust-resistant and strong yet lightweight.

The thickness and design of the frame can also impact its ability to hold heat and support the greenhouse under the weight of snow.

The Exaco Livingten also stands out as a fantastic choice when it comes to frames. Its thermal barrier makes it a unique option in the realm of greenhouses.


Choosing between a hardcover (rigid panels) and softcover (flexible materials) greenhouse depends on your winter conditions. Hardcover greenhouses, typically made with glass or polycarbonate panels, offer better insulation and protection against harsh weather.

Softcover greenhouses, while more affordable and easier to install, may not provide sufficient insulation in colder climates and can be more vulnerable to damage from snow and wind.


Proper ventilation is crucial in a winter greenhouse to prevent overheating on sunny days and to manage humidity levels. Look for greenhouses with adjustable roof vents, side vents, or louvered windows, which allow for controlled airflow.

Automatic vent openers, as found in many Hoklartherm models, can be particularly useful as they adjust the ventilation based on temperature changes.


Insulation is a key feature to consider for a winter greenhouse, whether you’re looking for the best portable greenhouse for winter or a more permanent structure. Effective insulation keeps the warmth in and the cold out, crucial for maintaining a stable environment for your plants.

Look for greenhouses with features like double or triple-wall polycarbonate panels, as seen in the Hoklartherm Riga models, or insulated glass like in the Exaco Livingten Greenhouse.

The R-value, which measures thermal resistance, is a good indicator of how well a greenhouse will retain heat.

Additionally, consider greenhouses with insulated foundations or the ability to add insulating materials to the flooring for enhanced heat retention.


Shelving is an often overlooked but important feature in a winter greenhouse. It allows you to maximize space, organize plants effectively, and can even contribute to the overall heat distribution within the greenhouse.

Consider greenhouses that offer integrated shelving solutions or have the capacity to add custom shelving.


Your winter greenhouse should offer protection not just from cold and snow, but also from other elements like strong winds and pests.

Look for features like heavy-duty seals, lockable doors, and reinforced coverings. The ability to add additional protective elements like snow load kits or wind braces can also be beneficial.
