If you're a commercial grower, you can never have too much space. Our 30ft wide polytunnels are the widest polytunnels that we offer and are therefore a cost effective choice for large-scale market gardeners and farmers. One of these large 30ft wide polytunnels could also be the perfect solution for a shared space for a community group. Click on 'What's In The Kit' to check what is included in the price, then simply select the length you require and you are ready to go. You will have expanded your undercover growing area in no time.
Before you complete your purchase, you will get the opportunity of even greater savings with our great bonus save deal - the more you buy the more you can save, as you add in some useful extras such as base rails, crop bars, sliding doors and staging options. Check out all the useful extras and accessories for your large polytunnel and make sure you have a polytunnel that will perfectly meet your requirements. A 30ft wide polytunnel makes sound business sense for many larger scale growers, so whatever you are growing and however much space you require, we can help you meet your growing goals.
This is the biggest single span Polytunnel we make. Designed for optimum strength, durability, space and versatility. Developing techniques and design features from our smaller tunnels, things like straight sides mean that the vast floor space created is enitrely productive. There are lots and lots of internal configurations that are possible. Strength comes from the 60mm galvanised steel hoops with the reassurance of Joint Braces.

If you are experiencing problems with your large polytunnel construction, our construction team are available to answer your questions and help in whatever way they can. Simply call 01282 601253 on week days between 9am-5pm...PLUS weekend cover on 07801 601253, between 9am-5pm or contact us. Alternatively, you can visit our construction resources website at construct.firsttunnels.co.uk.
We haven’t stopped there, we know many people build their polytunnels at the weekend or over a bank holiday when our office is closed, so we have also produced a series of Polytunnel Construction Videos. This collection of videos can be viewed anytime, on your home computer, and even your phone for when you are in the thick of things constructing your polytunnel.

Can you imagine a small football pitch to play with? Well I have that size of area at my disposal. Will I fill it, doubtful, but its now used for drying clothes, storing bikes, wood for my stove and of course my second hand couch and obligatory stove for my kettle - secret hideaway or working hard - my wife cant decide which. Granted I'm lucky to have the space, but Id be equally as happy with a smaller poly tunnel, obviously would have to lose the couch though. Thnaks First Tunnel, |

We supply Timber Hinged Doors at each end, Anti Hot Spot Tape, Timber Base Rails and of course the Framework to support our 200 micron Super Therm Polythene cover. These options are pre-selected below, but can be amended to suit your needs.
You will be required to secure the foundations into concrete, alternative methods of securing the large polytunnel can be selected, eliminating the requirement of concrete – see ‘Polytunnel Foundation’ section.
Select the options below in order to configure your Polytunnel and when you’re happy, press "Add to basket"
Your first big decision when choosing a Polytunnel is almost always..."What size is ideal?". But there's other important factors to take into consideration..."What type of cover do I want?". It might not sound like something to give a lot of thought to, but the cover you choose will affect your day-to-day Polytunnel management, what and how you grow. We have 4 options to choose from...
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 five year guarantee.
FOR USE WITH All crops where heat is important such as bedding/annual plants, propagation houses & over wintered vegetable production.
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.
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.

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.
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.
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 = 95%
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
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%
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
The strain on a tested sample when it stretches. This is also expressed in Pascals or MPa.
Super Therm = MD920/TD920
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
A test to measure the impact strength on a test piece of plastic, using a weighted falling 'dart'.
Super Therm = 450
This specialist film reduces light transmission to 65%, and ultimately the temperature inside the structure. This film is most useful where sun scorch is a problem for growers. It is also suitable for animal husbandry applications and other stock and storage houses where a great build up of heat is not ideal. This UV stabilised film is 180 microns (720 Gauge) and is supplied with a five year guarantee.
FOR USE WITH Animal Husbandry structures and those plants that would normally grow under a shade canopy.
