Are Polytunnels Waterproof?

Are Polytunnels Waterproof

Polytunnels are an excellent way to grow crops in cold climates. They are resistant to UV damage and easy to maintain. Additionally, they are inexpensive and multi-functional, allowing you to use them for multiple purposes. So how do you decide which type is right for you? Keep reading to find out more about these versatile greenhouses. It is possible to grow vegetables, herbs, and flowers even in the coldest climates.

Resistant to UV damage

Polytunnels are translucent, flexible plastic structures that create a micro climate inside. They also resist UV rays. Five Star Polytunnels offers XL horticulture polythene. These films are 8 layers thick and contain an additive called Metallocene. This makes the film stronger, thinner, and more flexible. These structures are also guaranteed for 8 years.

The K50 Clear plastic reflected most UVB rays and attenuated most UVA rays. SunMaster reflected less blue radiation and more red, far-red, and near-infrared rays. While both types of polytunnels were resistant to UV rays, they still failed to block the majority of incoming radiation.

When repairing or moving a polytunnel, it’s important to remember that nearby vegetation may cause damage. Even the slightest friction can lead to expensive repairs. Make sure that vegetation isn’t too close and prune as needed. If a problem does occur, repair the damage immediately.

Easy to maintain

If you want to grow your own food, one of the most practical ways to do so is by investing in an easy-to-maintain polytunnel. Even in the winter months, polytunnels can keep your crops healthy and produce. These structures are made of double-layer polythene reinforced with nylon mesh, which means that they are stronger, insulated, and more resistant to weather. However, they tend to be more expensive than regular polytunnels, and they do not allow for as much light as regular ones.

One way to ensure your polytunnel stays looking as good as new is to regularly repair any damage. Small snags and wind debris can cause damage to the plastic. Repairing small holes and rips takes just a few minutes and will increase the life of your polytunnel.

Multifunctional space

When considering a greenhouse, you need to understand what you want from it. If you want an extra-appealing garden, a space that produces large quantities of vegetables and fruit, or the ability to grow flowers and herbs in the back yard, then a greenhouse might be the best option for you. However, if your needs are more modest, polytunnels might be a better choice. These versatile structures can be expanded as your needs change, and they are cheaper than a greenhouse.

A polytunnel is similar to a greenhouse or cloche, but is generally made of plastic. Modern polytunnels are designed to allow you to grow plants and operate sowing and harvesting machinery inside them. This technology has changed the way strawberries are grown in the UK. Soft fruits and vegetables can also be grown in these structures. For protection against weather extremes, these structures can be equipped with foggers that reduce the temperature inside while maintaining a humidity level that is a good fit for the crops.


Polytunnels are a great way to extend your growing season and produce bigger crops. They are easy to assemble and do not corrode, but they do not hold heat as well as a glass greenhouse. While they are waterproof, they don’t keep warm as well during the winter and are not suitable for growing tender plants.

The walls of a polytunnel should be cleaned regularly with warm water and dish detergent. For more thorough cleaning, you can use specialized pressure bottles. This will help you get the most out of your polytunnel while preventing harmful algae and mold from growing. Ventilation should be done regularly every day. Most polytunnels come with movable windows that will help you ventilate them properly.

Easy to transport

Polytunnels are heavy-duty structures commonly used by commercial growers, but they are also affordable enough for the home gardener to buy and use. Prices for these structures begin at just a few hundred pounds, making them a great choice for many home gardeners. They are also easy to transport.

They are easy to store and transport, and their polythene covers are easy to clean. However, they are susceptible to damage and repair. To keep polytunnels in good condition, they should be regularly checked and tended to. If any damage is found, it should be repaired as soon as possible to prevent further damage.

The construction of polytunnels is faster and easier than that of permanent structures. They can be custom made to your specifications, and they are also much cheaper per square meter than traditional greenhouses. Furthermore, they are ideal for growing almost anything. The only drawback to polytunnels is that you may have trouble with thorny plants or fruit trees, as they may grow too large for the container.
