Top 8 Greenhouse Kits for High Winds

Strong winds are often overlooked when purchasing a greenhouse. As a result, strong winds can cause severe damage or even destroy your greenhouse if you don’t prepare properly. 

So, how do you know if your greenhouse can withstand high winds? Don’t worry, we’ve got you covered. 

There is no need to spend time reviewing specs or researching all the greenhouse kits on the market. In this post, we are going to go over the best greenhouse kits that have high wind resistance. Whether you are looking for a specific size, shape, panel material, or frame material we’ve got you covered. 

Let’s dive in. 

 

Features That Impact A Greenhouses Wind Resistance

There are several features that impact the wind resistance of a greenhouse and those are: 

  • Panel Material 
  • Panel Thickness
  • Frame Material 
  • Foundation Preparation 

Panel Material

The panel material and panel thickness have a significant impact on the wind resistance of a greenhouse. This is because durable and thick panels are less susceptible to strong winds. 

Durable materials won't bend or be easily blown away by strong winds. The most common panel materials found on greenhouse kits are polycarbonate and tempered glass. 

Both of these materials are highly durable and won’t easily break when experiencing high winds. 

When wind resistance is priority you want to avoid using plastic or poly covers. These covers provide very little protection against the wind. Often times, these covers will flap in the wind and can cause damage to your plants. 

Panel Thickness

While the panel material of a greenhouse is important the panel thickness plays a more important role in the wind resistance of a greenhouse. 

The panel thickness determines how durable the panels of the greenhouse is. Thick walls can withstand stronger winds. Thicker panels will not bend or flap when there are strong winds. 

One key aspect of panel thickness is the number of layers. Single layer panels are less durable and have a lower wind resistance than panels with multiple layers. The most common is double-wall, these walls have two layers and are found in many greenhouse kits. If you need the highest degree of wind resistance you can opt for triple-wall panels although they are less common but still available in some commercial greenhouse kits. 

Another factor of panels thickness is how “thick” they are. Greenhouses panels that are less than 4mm thick will provide very little wind resistance. With 4mm thick panels you will get a moderate amount of wind resistance. For a stronger greenhouse you want to opt for 8mm panels and for maximum protection against the wind you want 10mm double wall or triple wall panels. 

Frame Material 

The material of your frame plays a crucial role in the wind resistance of the greenhouse. When choosing a greenhouse frame material you want to choose some type of metal. 

When the priority is wind resistance you should never consider a plastic or PVC frame. These frame provide very little support against wind resistance.  

The two best options when choosing your greenhouse material is aluminum and steel. Aluminum frames are one of the most common materials used on greenhouse kits. These are highly durable and offer exceptional wind resistance. 

Aluminum frames with reinforced frames or extra-thick aluminum will provide more support and wind resistance than conventional aluminum frames. 

Steel frames are stronger than aluminum frames but they are also heavier and more expensive. Steel frames typically provide significantly more wind resistance than aluminum frames.

Foundation Preparation 

One way you can improve the wind resistance of your greenhouse is the type of foundation preparation. 

A foundation that is secured to the ground will improve a greenhouses wind resistance. The most common option is using a concrete foundation and securing the foundation to the greenhouse frame with cement.

Another option is to secure the greenhouse to the cement frame using screws or bolts. These also help increase the wind resistance of a greenhouse. 

An alternative is to create an alternative foundation made of wood or metal and bury it significantly under the ground to provide some additional wind resistance. 

If wind resistance is the priority you want to secure your greenhouse to the foundation in some way. If your greenhouse is not secure, when there are high winds this can cause your greenhouse to move and in extreme cases blow away. 

If you're not securing your greenhouse to your foundation you can use a tie-down kit to secure your greenhouse to the ground. These tie-down kits allow you to secure durable wires to your greenhouse. These wires attach to your greenhouse and are secured to keep posts in the ground.
