8ft Wide Polytunnel

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.

Polytunnel extras will not only allow you to make the most of your space, maximise yield and make your life easier, they can also allow you to get some great savings with our bonus save scheme. Buy extras such as base rails, crop bars, sliding doors or staging and you can save up to 20% on your purchase. 8ft wide polytunnels are great value for money, allowing you to cut costs on feeding your family. With these bonus savings, they are even better for your household finances.

If you are experiencing problems with your 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.

Excellent product, though some of the instructions are a bit vague and some of the diagrams are a little too small. Over all we have managed to construct most of it so far. We are still to install the second door, the aluminium rails and the polythene. We will get there eventually.

I had helpful advice when I emailed to help me choose the right configuration for me. Delivery was speedy. Everything arrived well packaged. Most of the items (aside from the wooden parts) were clearly labelled and described in the instructions. Plenty more nails than required (useful when heads get knocked off!) The instructions are reasonably clear, but the videos are really useful for seeing exactly what you need to do. The self tapping screws took upwards of 10 mins each to fix and the one day build time assumes you're fit, have nothing else to do all day, and have probably built at least one other polytunnel. But it's a sturdy and well constructed item, and I think very good value. Really looking forward to years of extending the growing season at my allotment!

Most people only build one poly tunnel for themselves in their life time. First tunnels supply the support info, manual, videos and telephone back -up that is only just second best to them actually build the bloomin' thing for you! Everything arrives logged and itemised and all you need, apart from the tools, is there down to the last nut and washer. Following the instructions step by step could be done by a simple robot. The only problems occur when you think you might have a better way of doing things! It's like the old joke about the most dangerous nut in a car is the one behind the steering wheel.

What's In The Kit

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 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"

Select Length

Select Type Of Cover

Help Me Choose

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...

Super Therm

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.

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.

View the terms of the Guarantee here.

Polythene Guarantee
UV Filters
Solar Radiation

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.

Thickness
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.

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.

Dart Test

Dart Test

Super Therm = 450

Smart White

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.
