When choosing a greenhouse, you’ll want to consider the moisture content of the snow you’ll be dealing with. Dry snow occurs in dry climates over interior regions of a state with very low temperatures. “Wet” snow, on the other hand, picks up moisture from large bodies of water. This type of snow weighs four times as much as dry snow and can wreak havoc on the roof of your greenhouse.
Cold climate greenhouses are transparent on all sides
A cold climate greenhouse is usually transparent on all sides, while a warm-climate greenhouse is opaque. However, a cold-climate greenhouse is made to retain heat, not transmit it. The material used in a cold climate greenhouse must be highly insulated. In general, polycarbonate is the best choice, as it has a high R-value and is more effective in reducing heat loss.
They are made of heavy-duty materials
The sturdiness of the greenhouse structure is an essential consideration for greenhouses in areas where snowfall is a factor. The cover of a greenhouse can be punctured or torn if it is flexible. Heavy snow can be as much as four times heavier than dry snow. In a windy area, the snow may even blow the greenhouse away. So, it’s important to choose heavy-duty materials for greenhouse construction.
They are insulated
A gothic-arched greenhouse can deal with ground-snow loads up to 30 psf. Its steep slopes also increase sunlight for plants. Compared to a traditional greenhouse, the Riga greenhouse has a better design for snow resistance. It has been tested with wind speeds up to 120 mph (three seconds) to ensure its structural integrity. However, this greenhouse has some disadvantages.
They are rust-resistant
If you are worried about the upcoming winter and want to ensure that your greenhouse can withstand the weather, you can choose a rust-resistant model. These types of greenhouses are made of durable materials such as aluminum, which is lightweight and strong. Despite the high humidity inside, these structures do not rust easily. Some of them even feature Polycarbonate panels for insulation. To find the perfect greenhouse for your needs, you must take some time to compare the main features.
They are built to withstand high winds
The design and construction of buildings can be critical to their resistance to the destructive forces of high winds. While it is theoretically possible to build a building to withstand 250 mph winds, this would be an expensive undertaking and is only justified in extreme environments. Building codes in places like Miami-Dade County, Florida, assume a design wind speed of 146 mph. Even at those levels, however, it would be a major step up from conventional practice.
They have double-paned windows
Double-paned windows are energy-efficient. The space between the glass panes slows down the transfer of heat and cold. Many double-pane windows contain argon gas, a colorless, odorless gas. This gas is more efficient than air at preventing heat transfer. This gas also reduces noise pollution from outside. If a leak occurs, argon gas will not harm the house.
They are tall
These greenhouses are designed to withstand heavy snowfall and wind. The panels that make up the walls are pre-assembled and ready to paint, which means there’s no need to worry about assembling the panels yourself. The walls are also primed to resist weather conditions, and they’re tall enough to hold three hundred pounds of snow. This makes them the perfect choice for regions where snowfall is a regular occurrence.
