Which Polythene Should You Choose For Your Polytunnel?

Polytunnels have come a long way over the years. They are now highly customisable structures with a myriad of uses. Simply by changing basic features like doors and coverings, you can completely repurpose your polytunnel structure. Replacement covers are available from all leading polytunnels supplies. Here's a quick guide to help you choose the most suitable polytunnel covers for your needs.

 


Super Clear Polythene

The most commonly used polytunnel cover, designed especially for use in the UK. Typically a 720 gauge polythene with a 95% light transmission rating. The high light transmission increases the spectrum available to plants and promotes maximum light filtration in the UK's low light environment.

 

Ideal for: Growing all summer vegetable and flower crops as well as overwintering hardier plants. Although this cover has high light filtration, it does not have high heat retention properties, so it doesn't offer protection against frost.

 

Thermal Anti Fog Polythene

Like the super clear polythene, this cover is also 720 gauge but has a couple of added benefits. UVA and UVB filters have been added to reduce condensation levels and consequently minimise fungal diseases. Thermal Anti Fog Polythene also has an Infra-Red additive which helps slow down the rate of heat loss through the cover.

 

Ideal for: Covering heated polytunnels as using this type of cover can save 15-20% on fuel costs. It's also good for any polytunnel environment where heat retention is important such as overwintering crops and propagation.

 

Super White Polythene

The polythene cover is 720gauge with a 70% light transmission rating. Less light means lower temperatures in your polytunnel which is helpful for light-sensitive crops or in sunnier climates.

 

Ideal For: Growing plants that don't like direct sunlight and would generally grow under a shady canopy. Due to the protection from the sun, this cover also lends itself for use in retail canopies and animal shelters.

 

Smart Green Polythene


This is a newer innovation in polytunnel covers. It is slightly thinner at only 600 gauge but still very durable. This cover has a 65% light transmission rating. Because the polythene is green in colour, it blocks a lot of red light and, as a result, creates an environment similar to the forest floor. Plants do not fight for light, so they won't go leggy as they sometimes do when grown under shade.

 

Ideal for: Creates the perfect habitat for forest-dwelling, shade-loving plants that respond well to the green light spectrum.

 

Green & White Polythene

A thicker polythene cover at 800 gauge that offers complete blackout with 0% light transmission. One side is green in colour, while the other is white.

 

Ideal for: A covering option that lends itself to several applications. It's ideal for storage areas, retail canopies, livestock shelters and even mushroom houses.
