Polytunnels are generally sturdy and long-lasting structures. However, they are also susceptible to damage and may need repair. Polytunnels should also be covered with a durable cover that is 720 gauge, or 180 microns thick. A cover made of this quality is typically guaranteed to last at least five years, but can last a decade or more.
Materials used for a polytunnel
The materials used in a polytunnel determine how durable and insulated it is. Wood is a durable choice and can last a long time if it is properly treated. Another option is plastic, which is cheaper but can break easily. Wooden structures can also last a long time, but they must be protected from the elements.
Polythene polytunnels are available in either green or white and are resistant to UV damage. They are commonly used for growing certain types of mushrooms and livestock. Depending on the materials used, a polytunnel can be very expensive or extremely inexpensive. A simple two-storey polytunnel can cost around $60.
Polytunnels come in a variety of sizes. Generally, they are around 10×12 feet. This is the right size for many home gardeners, and is much cheaper than a traditional greenhouse. You can start with a smaller size and then expand as your garden grows.
Before purchasing a polytunnel, you should consider the type of crops you plan to grow. For example, if you plan to grow vegetables year-round, you may want to buy a larger polytunnel. This will give you more planting space and more storage space.
In addition to sizing, you should consider the type of cover. Some polytunnels will have more internal bracing than others, which gives them greater flex resistance against wind stresses. Also, you can choose a polytunnel with a Ground Bar Kit to help prevent leaks from occurring. Some also feature front hinged double-skinned metal doors and a ground skirt with a wide opening.
Price of a polytunnel
Compared to greenhouses, polytunnels are much cheaper and offer more space for your growing needs. They also offer better ventilation and are much easier to customize. While greenhouses can offer greater protection from adverse weather and pests, polytunnels can be moved easily.
Prices range from about $50 to several thousand dollars for a commercial-sized polytunnel. However, if you plan on using the polytunnel for many years, you should consider investing a little bit more money in it. Commercial-sized polytunnels can be as large as sixteen feet by eight feet and can cost up to $3500. A smaller polytunnel can cost anywhere from $150 to $400.
If you’re planning on building a polytunnel yourself, you should consider the amount of effort required to construct the structure. A smaller model is easier to install and may require less time. Some models come with poles and metallic pins for securing them to the ground. You can easily download instructions manuals online. They will take you step-by-step through the construction process.
Price of a polytunnel kit
If you’re looking to start growing your own food this year, then a polytunnel kit is the way to go. They’re great for raised beds, market gardens, and kitchen gardens and are easy to store until the next growing season. If you live in a region with mild winters, you can even use a polytunnel throughout the winter. If your location is more prone to wind, you should consider buying a heavier-duty plastic cover.
The cost of a polytunnel greenhouse kit is usually about $500, but you can also build a polytunnel yourself for less than $40. The process of building a polytunnel is easy and takes less than 30 minutes. Because you can move it from one place to another, a polytunnel is ideal for rotating crops and ensuring a successful growing season.
Planning permission for a polytunnel
If you’re considering building a polytunnel on your allotment, you will need to obtain planning permission. A polytunnel is a greenhouse or an outdoor building that stands three meters or more off the ground. It should be located at least 2m from the boundary of the site. There are several restrictions that apply. For example, you cannot build a polytunnel where there is a listed building or if the area is an Area of Outstanding Natural Beauty.
While domestic polytunnels don’t need planning permission, a commercial polytunnel does need planning permission. This type of structure is usually cheaper than a greenhouse, but the total cost of the building will depend on the quality and size of the structure.
