Polytunnel plastic sheeting is durable and won’t split or tear. It also has a long-lasting anti-fogging effect. However, there are some risks involved, including the possibility of damage. Here’s a look at how to take care of it.
Polytunnel plastic sheeting is strong
Polytunnels are great for a variety of reasons, from growing crops to protecting crops from pests. They can create the perfect growing environment for vegetables, fruit, and flowers, all while providing protection from harsh weather conditions and pests. This makes them a popular choice for many people and an important part of any garden.
It will not easily tear or split
A polytunnel is made from polythene, a very strong plastic. As long as you don’t get it wet or put it on a high windy day, the cover should last for many years. If you do find that it tears or splits, you can easily repair the tear by using tape. Start from the middle of the tear and work outwards. Try not to leave any air bubbles as these will attract moisture and undo your mend. You can also use a rounded handle of a pair of scissors to rub the area. This will help to seal the tear and ensure that the patch is secure.
A polytunnel can be built using a kit, which means that you will save hundreds of pounds in construction costs. However, you must have basic DIY skills or the help of a friend. When installing the cover, it is best to do it on a warm day as it will make the plastic more pliable and easier to stretch over the frame. It is also important to find a level site. In addition, if you have an exposed site, it may be a good idea to install hedging or fencing to protect it from damage.
It has a lifelong anti-fogging effect
If you’re looking for a durable, anti-fogging polytunnel, Polythene sheeting is the answer. These materials are durable and feature a unique additive called lumisol, which helps to control the amount of water that collects on the film. The result is less water dripping onto the plants underneath. It’s a lifelong anti-fogg effect.
Fogging occurs due to the accumulation of water vapor on plastic surfaces, which is caused by changes in temperature. The difference in temperature between the interior and exterior surfaces of plastic film leads to condensation. The moisture forms on the inside of the material, which causes it to “sweat”.
Another way to measure the anti-fogging effect of plastic is to look at the speed at which water droplets spread. Digital fast frame imaging showed that the water droplets spread in 93 milliseconds. The human eye blinks about 100 milliseconds.
It is prone to damage
One of the most common problems with polytunnels is damage to the polythene cover. Bamboo sticks and thorns on plants often clip against the plastic, causing small nicks that can develop into rips. Birds can also get into the polytunnel, causing damage to the glass. This can be avoided by using a transparent repair tape, which can be applied to the plastic cover and greenhouse glass.
Although polytunnels are designed to last a long time, they will inevitably succumb to damage. Nevertheless, the best way to prolong the lifespan of your polytunnel is to take good care of it. You should avoid exposing it to extreme weather conditions such as high winds, rain, or extreme temperatures. It’s also a good idea to take precautions to avoid any damage caused by the sun’s rays.
It requires replacement every 4-5 years
If you have purchased a polytunnel, you may be wondering how often you need to replace the plastic covering. You may be worried about the expense and how the process affects the environment. Thankfully, there are a few things you can do to make the process as easy as possible.
Ideally, you should replace your polytunnel cover every four to five years, however this will depend on how much sunlight it receives. If the plastic is exposed to direct sunlight, the cover should be replaced sooner rather than later. In addition, if your polytunnel is larger, you should test the polythene to make sure it can withstand the elements. This will prevent the cover from failing during inclement weather.
The good news is that today’s polythene is surprisingly resilient. It can withstand cold and hot weather, and will flex under strong winds. The material is also incredibly resistant to snow. If snow does fall inside, you can wipe the surface of the polythene with a soft brush to remove it. Many polytunnels even come with double doors so you can open them to let fresh air in during super hot weather.
