How Long Do Polytunnels Last?

How Long Do Polytunnels Last

When it comes to polytunnels, it is essential to invest in a high-quality polythene cover, as cheaply made ones can split easily. Most polytunnels will last for up to eight years and are usually covered by a warranty. If your cover becomes damaged, you can buy spares or repair it temporarily using tape. Ideally, however, you should replace your cover as soon as possible.

Materials used to build a polytunnel

Building a polytunnel is an excellent way to extend your growing season, protect your crops from the elements, and increase your harvest. The great thing about these structures is that you can erect them yourself, saving money on hiring an expert. Here are a few things to keep in mind when constructing your polytunnel.

Firstly, you need to make sure that your polytunnel is built sturdy and will last for years. The basic construction of a polytunnel is very simple and is done with galvanised steel hoops. These are then connected by stabilisers and a ridge. They are usually built on top of a bed of soil.

It is important to choose a site that receives ample sunlight. For best results, choose a site facing east or west. Avoid placing your polytunnel under a tree, as the roots can grow in time. In addition, make sure you have sufficient space to move around the polytunnel site. The larger the polytunnel, the more difficult it will be to move it around.

Sizes available

Polytunnels are available in a wide range of sizes and shapes. The choice of size is dependent on how much space you have in your garden. Some people have very large gardens, and therefore, need a larger polytunnel, while others have smaller gardens. No matter what you choose, you’ll need to plan ahead for the space you have available.

When considering the size of your polytunnel, keep in mind that the larger the tunnel, the larger the space it will take up. Larger polytunnels are generally wider and longer, which means more planting space and storage space. However, if you don’t have much space or have young children, you may want to consider purchasing a smaller tunnel. Regardless of the size of your polytunneling system, make sure you choose a durable polytunnel that will last for years.

Polytunnels can be made larger by purchasing additional arches and a larger cover. Polytunnels can be built to be either sheltered or exposed to the weather, but if they are placed in an exposed location, they should be constructed using a stronger structure and better storm bracing.


When considering the ecological benefits of polytunnels, it’s important to consider the carbon cost of the structure itself. This involves the CO2 emissions generated during production and transport. For a standard polytunnel, this CO2 emission factor is around 22g CO2/tonne-km. However, this figure will vary depending on the company and the type of polytunnel used.

The size of the polytunnel will affect its cost. For larger gardens, it is advisable to purchase the largest polytunnel you can afford. This will give you more space for your equipment and plants. Additionally, larger polytunnels can double as a work space.

Plants that grow well in polytunnels include cucumbers and artichokes. In addition, herbs such as rosemary and oregano are good choices for polytunnels, as they help retain moisture. Herbs such as oregano will also repel pests and protect surrounding crops.

Repairing a polytunnel

If you have a tear in your polytunnel cover, you can repair it easily with tape. You can get some from your polytunnel supplier. The tape will help strengthen the repair. Remember to apply it to both the inside and outside of the tear.

First, you need to consider the weather. If the polytunnel is located outside, the soil can freeze and cause the roots to die. If this happens, you need to move your sheep to a nearby shelter. You may be able to find a nearby farm that is willing to take them. In the meantime, you need to assess the damage done to your polytunnel. The damage may have an adverse effect on the growth of your crops, especially during the winter months.

If the tear is large, you should cut off the ripped part of the polythene. This will prevent the polythene from flapping around and tearing the frame. In addition, if there is a tear on the polythene cover, you should replace the cover with new tape to prevent it from getting damaged in the future.
