Don’t let the snow or cold weather stop you from getting a greenhouse. If you choose a greenhouse with the right materials it can withstand snow and cold weather with ease. 

Unfortunately, It can take hours or reacher to determine which greenhouse is best for snow and cold weather. 

Don’t worry, we’ve got you covered. 

In this post, we are going to go over the top greenhouses for cold weather and snow. We will go over the best greenhouse of different sizes, shapes, and materials to help you find the perfect greenhouse. 

Let’s get started. 


Can you have a greenhouse in cold climates?

Yes, you can have a greenhouse in cold climates but not all greenhouses are made for cold weather.

There are some key features of a greenhouse that make it able to withstand cold weather. The thickness of the panels and the type of frame material will determine if a greenhouse can withstand the snow and cold temperatures. 

The thickness of the panels determines their insulating ability. Thicker walls provide better insulation and allow your greenhouse to withstand colder temperatures.

For cold temperatures you double-wall polycarbonate or glass panels perform best. In addition, you want polycarbonate panels that are at least 6mm thick. 6mm thick. If opting for glass 4mm tempered glass panels are ideal for cold weather. 

The frame thickness and material help determine its snow load and wind resistance. Aluminum and steel greenhouse frames perform best in cold weather.

Another important factor in wind resistance and snow load is the panel thickness. If you will be experiencing heavy snow or strong winds a greenhouse with 8mm twin polycarbonate walls are ideal. 


Can plants survive in an unheated greenhouse? 

Yes, plants can survive in an unheated greenhouse. But, it's important to monitor the temperature inside your greenhouse. Heavy polycarbonate panels or glass panels are a great way to keep your greenhouse insulated. Your greenhouse panels will keep the cold temperatures outside while also helping absorb the heat and keep it inside. 

If temperatures get too low it will be necessary to use external heating to ensure that your greenhouse maintains its temperature inside.
