Polytunnels

How Long Do Poly Tunnels Last?

How long a polytunnel will last largely depends on the quality of its frame and the quality of its polythene covering. Fortunately, there are several different types and qualities of polythene to choose from. These will be discussed in more detail shortly. Generally, polyethylene coverings will need replacing every five years, although higher quality ones can last up to 10 years.

Building a polytunnel

When it comes to building a polytunnel, a little research will go a long way. Start by checking out some build guides online. These can be a great help to you and can provide you with step-by-step instructions. Also, they can show you what tools and parts you will need.

First, you need to prepare the soil where you want to put the polytunnel. This can include leveling the ground. You will also need to anchor the structure. Using anchors will make it easier for you to move the polytunnel to different places.

Next, you need to make sure the foundation tubes are long enough. They should be six feet long and driven into the ground at a depth of three feet. Once they are in, make sure to use a spirit level to check their level. If you can’t afford to buy the foundation tubes, you can use offcuts from scaffolding poles or mains water pipe. Just make sure to cut them to the proper length and drive them into the ground to ensure they are level.

Repairing a damaged polytunnel

A polytunnel is an extremely useful structure that helps keep out cold temperatures, which is vital for growing plants. They are traditionally used to grow fruits and vegetables and to keep livestock indoors. However, they can be vulnerable to damage. Here’s how to repair a damaged polytunnel to prevent it from becoming a complete loss.

First, inspect the frame and cover of your polytunnel. If there are sharp edges or tears, these should be taped up. Also, make sure that you have installed special tape between the frame and the cover. This will prevent damage to the cover and will help extend its life.

A tear in the polythene may be a minor tear but can lead to a larger tear. If the tear is too large, you may need to cut off the affected area. Otherwise, you’ll risk the frame deteriorating further. If it’s a small tear, the polythene cover can be repaired using a polytunnel repair tape. This repair tape is available from polytunnel suppliers.

Proper maintenance of a polytunnel

A polytunnel requires regular maintenance in order to remain in good condition. This includes keeping it clean and preventing damage. It is important to regularly check for holes and other damage. If you notice a hole, it is a good idea to use a repair tap to fix it. For larger rips and tears, you should use two pieces of tape in an X-shape. Keep in mind that thick plastic can only give so much, so cleaning is crucial to maintaining the quality of your polytunnel.

Regular maintenance can also extend the lifespan of your polytunnel. Regularly removing leaves and debris from your polytunnel is a good idea as they can puncture the plastic. The plastic will last for a couple of years if you take good care of it, but it will degrade eventually.

Another important maintenance is checking for damage caused by wind. Winds can cause damage to polytunnels as they swing from different angles, causing various bits to flap around. Using storm braces will help prevent polytunnels from blowing away in winter gales.

Cost of a polytunnel

The cost of a poly tunnel depends on its size and construction. Commercial-sized polytunnels can be as large as sixteen feet across by eight feet tall and thirty-six feet long. These structures start at approximately $3,500, but smaller versions are far cheaper. These greenhouses are made from powder-coated aluminium, which helps to prevent oxidation. They also feature toughened glass for extra protection from bad weather.

Choosing a polytunnel with a low carbon footprint is also important, as the material used to make it is usually renewable. As a result, polytunnels are more eco-friendly than many other building materials. The carbon footprint of a polytunnel is calculated by looking at its entire lifecycle, from its feedstock to its delivery on site.

Once installed, polytunnels are an excellent option for growing crops. They are able to extend the growing season and yield bigger crops. Many of these tunnels are pre-assembled for easy installation. They have a durable UV-stabilized polythene cover, and stainless steel hardware.
