Polytunnel Covers FAQ's

See below answers to some common questions we get asked about polytunnel covers.

The plastic for polytunnel replacement is made with materials that can withstand UV rays. In most cases, you can go up to 5 years before you need to replace your polytunnel cover. However, with a little bit of care and maintenance, you may get a few extra years out of your cover.


During the warmer months, you may only need to hose down your polytunnel cover. However, the polytunnel plastic may develop an unsightly layer of algae over the winter months. If you do notice even a small algae growth, it is recommended that you clean it as quickly as possible to prevent the algae from spreading and compromising the effectiveness of your polytunnel covering.

To clean our polytunnel cover, simply use a large weighted cloth. Spray a gentle cleaning fluid over the polytunnel and then cover with a large cloth and, with the help of a friend, gently pull the fabric to and for to remove the algae. If any algae appear on the inside, remove it quickly by spraying the cleaning fluid on the algae spots before dipping a sponge in water and cleaning off the algae.


When it comes to polytunnel covering, the best plastic for a polytunnel is polythene. This type of plastic allows more natural sunlight into the tunnel which is essential to the plants growing within.
