Swipe to scroll through tabs

Our most popular polythene cover incorporates an additive that increases its Thermic efficiency, yet still retains 90% light transmission. In simple terms the polythene helps trap and preserve higher temperatures inside the structures for much longer - in heated structures, a 15-20% fuel savings can be achieved. A beneficial side effect of this added additive is that light entering the polytunnel is diffused - scattering light evenly throughout the structure. This UV stabilised film is 200 microns (800 Gauge) and is supplied with a seven year guarantee.

FOR USE WITH All crops where heat is important such as bedding/annual plants, propagation houses & over wintered vegetable production.

7m wide – 1.29kg per linear m - 50m roll would weigh 64.5kg
9m wide – 1.66kg per linear m - 50m roll would weigh 83kg
11m wide – 2.03kg per linear m - 50m roll would weigh 101.5kg
15m wide – 2.77kg per linear m - 50m roll would weigh 138.5kg

Please note - to help identify the polythene type and validate the guarantee, a series of numbers and letters are intermittently printed on the polythene. The printing will appear approximately 1m from the side which will normally be buried into the ground or trimmed off.

Super Therm Properties

Supplier

Our polythene is exclusively sourced from Sotrafa in Spain, the world's biggest producer of horticultural film with an enviable reputation for quality thanks to exhaustive testing in the demanding weather conditions of Almeria.

First Tunnels are the sole distributor of Sotrafa products in the UK, and we are proud to work with the global leader to deliver the best possible products for our customers. UK suppliers make cheaper alternatives, but the quality simply doesn't compare.

Warranty

Although guaranteed for 7 years against its biggest threat of sunlight degradation, when fitted correctly, it is not uncommon to hear our polythene covers have lasted in excess of 10 years.

Polythene Guarantee
UV Filters

Sunlight is the biggest enemy of polythene. While it's essential for the wellbeing of whatever you're growing, it also 'kills' polythene in much the same way you can find old discarded crisp packets lose their colour and become very brittle. First Tunnels polythene covers are developed and tested in the extreme conditions to give optimum performance and are UV stabilised to prevent the polythene from breaking down prematurely.

What is a KLy?

A Kilo-Langley is the measure of Solar energy radiated in 1 year. It varies from a minimum of 60 KLy in the Polar regions to 120 KLy in warm regions, and to a maximum of 200 KLy in the African desert. Southern Spain receives about 140 KLy whereas the UK receives about half of that, just 78KLy.

Solar Radiation
Thickness

Our Super Therm polythene is 800 gauge/200 micron and made up of 3 layers for outstanding strength and performance.

We use a 3 layer polythene made of exceptional quality material, which has a hugely beneficial thermal effect.

The common misconception about polythene is the more layers, the better the product. Unfortunately this isn't true. More layers simply hide poor quality films, which are sandwiched inside a very average inner and outer skin. The result of these multi-layer (often called 5 or 6 layer) films is a noticeably poorer all-round performance - the thermal effect is significantly decreased.

Thickness
Optical Properties
Total Transmission of Visible Light

Total Transmission of Visible Light
The amount of available light entering the polytunnel through the film. Measured as a percentage of total light.
Super Therm = 90%

Diffusion

Diffusion
The scattering of direct light entering the polytunnel ensuring no shadows, so all plants receive equal light. Measured as a percentage of total light.
Super Therm = 30%

Thermal Effect

Thermal Effect
A pocket of additives within the layers of the film that ensure and maintain a stable and optimum temperature within the polytunnel, especially during the night when it is colder.
Super Therm = 85%

Mechanical Properties
Strength at Break

Strength at Break
The load on a tested sample when it breaks. This is expressed in Pascals or MPa.
Super Therm = MD24/TD23

Elongation at Break

Elongation at Break
The strain on a tested sample when it stretches. This is also expressed in Pascals or MPa.
Super Therm = MD920/TD920

Creep

Creep
As the weather changes becoming hotter or colder, so the Polythene expands and contracts. Creep is the terms used to express this.
Super Therm = 5

Dart Test

Dart Test
A test to measure the impact strength on a test piece of plastic, using a weighted falling 'dart'.
Super Therm = 5

Please note - to help identify the polythene type and validate the guarantee, a series of numbers and letters are intermittently printed on the polythene. The printing will appear approximately 1m from the side which will normally be buried into the ground or trimmed off. Please retain a small piece containing the letters and numbers to validate the warranty. View the terms of the Guarantee here.

This is a good quality cover which I used on an old frame that I inherited on my allotment plot. It was easy to put on to the six metre tunnel with four of us choosing a calm day. We used the trenching in method and have achieved a tight fit over the frame. I am very pleased with the result and hopeful that it will last for the seven years.

Good product. Pleat folding to centre line is brilliant. Luckily we worked it out before unfolding it all but it would be wise to advise first timers such as us of this aid to handling a large sheet of plastic. Overall, advice on assembly was rather limited (but there are useful videos on the web).

Wasn’t too happy with the way the plastic was prepared this time. Years ago it was folded and put into a box, now it’s put onto a roll. Number of crease marks which in time will crack and will need repaired with tape, shame due to the money paid. In addition, it no longer comes with the chemical applied which reduces condensation. On the original tunnel plastic before one moved it the plastic was great from here, now one’s getting condensation every morning.

I ordered this product to fit my own built small poly tunnel after finding them on the internet. Fast and excellent service. Have fitted the product and as my first tear on an allotment- time will tell. I anticipate reviewing whether to create or buy a new larger unit next year and will come back to these suppliers. Very happy so far.

What is the Minimum Order Value? 
We sell replacement polythene by the metre, 25m or 50m rolls in various widths with no waste and no cutting charge. Order values less than £50.00 will incur a £4.95 delivery charge. Please see the delivery tab for offshore delivery charges.

Does the Polythene come with a warranty?
Our Polythene is supplied with a guaranteed for 7 years against its biggest threat of sunlight degradation. When fitted correctly, it is not uncommon to hear our polythene covers have lasted in excess of 10 years.
Sunlight is the biggest enemy of polythene. While it's essential for the wellbeing of whatever you're growing, it also 'kills' polythene in much the same way you can find old discarded crisp packets lose their colour and become very brittle. First Tunnels polythene covers are developed and tested in the extreme conditions to give optimum performance and are UV stabilised to prevent the polythene from breaking down prematurely.
Please note - A series of numbers and letters are intermittently printed one metre from the edge, which should be either dug into a trench or trimmed off after installation. This printing is essential to help identify the polythene type and validate the guarantee.

Is there an inside or outside to my Polythene cover?
Each face of the Polythene sheet is identical, there is not a right or wrong side when choosing which face goes on the inside or outside of the Polytunnel structure. If condensation is a problem we have Sunclear available which is a non-toxic coating that reduces this effect.

Where is the Polythene Sourced from?
Our polythene is exclusively sourced from Sotrafa in Spain, the world's biggest producer of horticultural film with an enviable reputation for quality thanks to exhaustive testing in the demanding weather conditions of Almeria.
