Quite small and yet perfectly formed, our 8ft wide polytunnels are a popular choice for domestic use, for gardens, allotments and other little community spaces. No matter how much growing space you have you always want more but an 8ft wide polytunnel is easily big enough to allow you to grow food all year round. Just choose the length of tunnel you require - we recommend going for a tunnel that is as long as you can fit in your space - there is always something more you will want to cram in! Then just click on any extras you may wish to buy. Not sure what's included? Click on 'What's In The Kit' to find out what you need to know.

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.
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.
You will be required to secure the foundations into concrete, alternative methods of securing the 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.

Unique to First Tunnels... We offer the option of the hoops of your Polytunnel to be supplied in a two or four piece design - Read the 'Pros and Cons' of each type, below...
Four piece hoops have smaller sections making delivery easier and cheaper whereas two piece hoops have larger sections that require bigger, more expensive transportation.
When ordering your polytunnel, time and consideration should be given to thinking about precisely where the delivery will be made. A 12ft x 25ft polytunnel would typically consist of about 10 items and weigh 160kg in total. The largest items of your delivery will be the hoops.
A delivery to your home might sound convenient, but please consider how you will transport the parts to site. Our four piece hoops will fit into the avarage family saloon, the two piece hoops will require a van. Obviously, the bigger the polytunnel, the larger the hoop sections.
Four piece hoops are the modern and customer focused approach with added hoop joint strengtheners. Just as strong if not stronger than the traditional two piece hoop. However the two piece hoop, doesn't require hoop joint strengtheners and is the favoured design for many suppliers, it is a lower cost to produce and quicker and easier to manufacture.
A 2 piece or a 4 piece hoop?
Without getting too techy...A two piece hoop has one joint in the centre. Granted the number of joints in a four piece hoop is three but by spanning the two outer joints with heavy duty, steel joint straighteners this undoubtedly makes a four piece hoop as strong, if not stronger as the conventional two piece design. These Hoop strengthening joints are included as part of every complete Polytunnel kit, they are not required to be ordered extra like some competitors who also provide four piece hoops.
See these strength joints in action. View our 4 piece hoop withstanding an Atlantic storm with 60mph+ winds.
When constructing, joining four pieces takes a tiny bit longer than joining two pieces.
It's true... constructing a four piece hoop does take longer, perhaps 1-2 minutes per hoop for the average person. And like anything the more you do the quicker you become. So choosing two piece hoops might shave about 10 minutes off the complete build time of a typical 12ft x 25ft polytunnel and 10 minutes is less time than you'll spend making a brew.
Four piece hoops are a quality solution engineered, tested and produced with the customer in mind. Two piece hoops are a solution for an easier manufacturing process.
Why do we do a four piece hoop? - It's not cheaper, neither is it more profitable for us.
So Why...Authentic reviews from actual customers are an important resource for improving and addressing the needs and wants of our customers...We listened, you suggested a four piece hoop (for many reasons), we made it happen, and now you simply decide which you prefer..two piece, or four.
It's not AS easy to supply a four piece hoop - we have to roll the four profiles, swage each end (to slot back together) and then supply additional fixings and storm strengthening joint, not to mention the Q clips (all included at no extra charge). A two piece hoop is easier from a manufacturing point of view, but we aren't here for ourselves we are here for you.
We must be doing something right...check out our customer reviews.
We have five options available. Foundation Tubes can be driven into the ground (if the polythene is to be trenched) alternatively you can use Anchor Plates. The Screw Anchor can be used if ground conditions are suitable. If you have a solid base of concrete or timber then Base Plates will be required.
We have three options available. The Trench method requires a trench digging all around the perimeter of the tunnel approx. 30cm wide and no less than 40cm deep. Quicker and easier than trenching the cover, are Base Rails, which are available in Timber or Aluminium versions.
We have two options available. Crop Bars are attached to every hoop apart from the first and last, Twin Support Brace runs down the full length of the tunnel, either side of the central ridge, both are ideal for hanging baskets, suspending canes/nets & crops.
We have three options available. Side Ventilation is a fixed rail (Timber or Aluminium) underneath which, is fixed a net windbreak, allowing ventilation and air flow. In addition we also have Timber Side Ventilation & Screen, which allows the net to be covered through the use of a screen, which can be lowered/raised, helping control temperature and air flow. Please note, the Screen is not compatible with Aluminium. All options available, for one or both sides.
Ground Cover inhibits the growth of annoying weeds. Acting as an excellent sub-base for use with bark, mulch or gravel. Ground Cover provides total floor coverage, supplied with metal staples.
Staging introduces a work surface at the ideal height of 75cm, significantly adding growing space. Complete with brackets, allowing you to attach a worktop (not supplied) of your choice.
Polythene Care Kit contains 1 roll of 4 inch repair tape and a 2.5 litre container of Algon Organic.
Overhead Irrigation comprises a water pipe suspended below the central ridge. Supplied with a header pipe, down tubes, sprinklers, inline tap, pressure regulator and hose connector. This complete kit is ready to go, just connect a hose and you’ll be amazed how quickly it will pay for itself in terms of time, money and improved productivity.
Automatic Overhead Irrigation is supplied with the added advantage of a weather resistant, battery operated hose end water timer. Essential for those days when you just can’t be there to operate the system manually.
All Polytunnels supplied come complete with two doors. We have hinged and sliding door options...
The top panel is covered in Shade Net to allow ventilation whilst the lower half is covered with polythene to prevent low level draughts.
The Outer Door Frame is 75mm x 47mm, whereas the Inner Door is 50mm x 50mm. All timber used is FSC® certified.
We also offer a DIY option...make your own doors. If you prefer to build your own bespoke doors - you can exclude the doors and timber end frames and receive a discount.
All door panels are covered with polythene, ventilation is easily controlled as you can slide the doors open to leave any gap of your choice. Sliding doors sit securely on the doorframe, flush to the polytunnel, and out of harm's way.
The Outer Door Frame is 75mm x 47mm, whereas the Inner Door is 50mm x 50mm. All timber used is FSC® certified.
We also offer a DIY option...make your own doors. If you prefer to build your own bespoke doors - you can exclude the doors and timber end frames and receive a discount.
