16ft Wide Polytunnels

If a 16ft polytunnel is just the right size, not too big and not too small, then you have come to the right place. Simply select the 16ft option and you will be able to choose to purchase a polytunnel kit containing everything you need to make a tunnel of just that size. You can click 'What's in the kit' to find out more about exactly what is included with your 16ft polytunnel and should you require anything else, we have just what you need in our wide range of add-ons and accessories.

Crop bars, base rails, sliding doors and staging can all make it easier to get a bumper yield from your 16ft polytunnel, whether it is for a large domestic set up or commercial use. Don't forget, adding on those extras could not only make your life a lot easier, it can also save you money with our great bonus savings scheme. You can tot up savings of up to 20%! A fairly large polytunnel such as this one is the perfect step up into commercial production and is the smallest commercial size polytunnel we provide. It could be the perfect, cost-effective way to boost your smallholding or other small business venture.

Tech Specs

Although the smallest in our range of Commercial structures, the 16ft (4.88m) wide Polytunnel is ideal for many of the demands placed on it by professional growers. The shape lends itself to exceptionally good clearance for working, with ample height for cultivating tall plants and for hanging baskets. It's super strong thanks to 50.8mm diameter E370 high tensile pre-galvanised steel tubing. Every component of this Polytunnel has been developed specifically for this structure, no adapting, no fuss.

Instructions

We have two construction guides for our 16ft Wide Polytunnel Model.

16TR for polytunnels who require the cover to be buried in a trench.  16BR for polytunnels that have Base Rails eliminating the requirement for digging a trench

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 polytunnels.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.

The support hoops are 51.5mm diameter, galvanised inside and out. The crop bars and various strengthening components are similar quality. Door framing, hinges and staples etc all top quality. Nothing was skimped on, no corners cut. Quality covering as well, of course.

What's In The Kit

We supply Timber Hinged Doors at each end, Anti Hot Spot Tape, and of course the Framework to support our 200 micron Smart Clear Polythene cover.  

A trench will need to be dug around the perimeter of the Polytunnel to secure the structure in place. Don't under estimate how long & tiring, digging this trench can be - Eliminate the requirement of this trench by ordering Base Rails.  This alternative 'Ground Fixing' method and other useful additions such as Sliding Doors, Ventilation, etc, can be added, please see our Optional Extras.

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 5 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.

5 Year 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.

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.

Smart Clear

This high quality Polytunnel film has been designed specifically for the UK where low light levels are common. This film allows 90% light transmission allowing through more of the light spectrum used by plants. It also scatters light entering the polytunnel. This UV stabilised film is 200 microns (800 Gauge) and is supplied with a five year guarantee.

FOR USE WITH All crops which are frost hardy, where you don't need to introduce heat, such as over wintered nursery stock, hardy herbaceous perennials, or where the poly tunnel is only to be used for summer production of vegetables or flower crops.

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.
