Commercial Economy Range
The economy range offers a great entry-level tunnel for the keen hobbyist looking to grow to the next level.
Whilst it is without some of the more sophisticated features of our commercial models (such as cover tensioning system), it is still a great option at a competitive price point.
Designed with a 5-year design life for the budget-conscious individual.
The economy range is constructed with a lightweight framework that does not come wind & snow loaded and thus will require wind protection and heating during winter snowfall.

With over 50 years of experience designing and manufacturing polytunnels, we know that quality counts, that’s why we build our polytunnels to last. If you are comparing us on price against a competitor, you must look at the detail of what you are actually buying, here are some tips on what to look for:
Our 4-piece hoop is made up of a 2-piece arch connected to a straight leg. The leg connection is located on a vertical plane meaning the hoops can withstand a heavier load. Manufacturing a hoop in this way also makes the hoop more customisable by giving the customer the ability to increase the height of the straight leg without compromising the stability of the single span.
Other manufacturers of Polytunnels often have their connections on the curve of the hoop which compromises strength and allows the hoop to ‘snake’. To combat this, extra bracing brackets are used resulting in increased materials, labour and cost.
Our timber is fully tanalised to reduce the speed of rotting.
The strength of our brackets and fittings have been proven for over 40 years and have been specially designed and manufactured in-house. Bespoke fittings are designed to simplify the construction process, thereby reducing the construction cost.
Different crops and growing systems require different solutions, which is why we offer a range of options to suit your individual requirements and budget. Options include; doors & louvres - foundations - brace and crop bars - choice of polythene covers - ventilation systems and irrigation.
Visqueen’s British made polythene allows UVB to enter the greenhouse unlike normal glasshouse films and glass. This has many benefits including enhancing the fragrance, taste, colour of crops with the added advantage of earlier harvesting and longer post-harvest shelf life. It also has a unique condensation reduction additive to further reduce light-loss. Our polythene is guaranteed for 7 years*
*incremental guarantee from invoice date
Our ground tubes (Foundation Tubes) are 1m long, they are ArmourGuard galvanised treated with a 2.5mm wall thickness.

Polythene film: Diffused or Clear?
Light Transmission- Light transmission is the quantity of light going through the polythene, measured by %.
- For temperate climates, a rate of higher than 85% is the target.
- Where the heat in the tunnel is retained during the night.
- This is measured by thermal retention + thermal transmission = 100 and is expressed as %.
- The higher the thermal efficiency, the better the polythene retains heat.
- The higher the thermal transmission the more energy is lost.
- The anti-drip coating reduces condensation droplets and produces more of a film of water.
- Reduces the risk of droplets then dripping which can cause fungal diseases.
- Improves the quality of light for photosynthesis, Droplets of water cause light refraction reducing the quality of light.
Lumisol Clear - Clear Polythene
The clear polythene improves the passage of light into the tunnel to promote photosynthesis.
Clear polythene is measured by haze. The lower the % the clearer the polythene appears and the more light is allowed to be transmitted.
- Our clear polythene has 30-35% haze.
- Our clear polythene has 88-92% light transmission.
- Our clear polythene has 80-85% thermic effect.
Improves the quantity of light to encourage photosynthesis.
Encourages early crop yields and crop strength.
Increases daytime temperatures.
5-year incremental guarantee, although a 12-14 year lifespan is not uncommon.
Lumisol Diffused - Diffused Polythene
The diffusion effect ensures better light distribution inside the polytunnel, Diffused Polythene is measured by haze.
The higher the % the cloudier the film is, the more light it defuses.
- Our diffused polythene has 90-93% haze.
- Our diffused polythene has 87-91% light transmission.
- Our diffused polythene has 80-85% thermic effect.
Reduces the stressful effect of direct sunlight on the plants.
Reduces the risk of leaf burn and crop deformation.
Encourages a more uniform ripening and colouring of the fruit as less shadowing is cast.
Note: designed for use in very luminescent areas of the UK.
5-year incremental guarantee, although a 12-14 year lifespan is not uncommon.
Over a certain length, commercial tunnels can struggle with stagnant air in the middle of the structure that airflow from open doors cannot circulate.
The best recourse for this is to opt for side ventilation. Whether manual winch, gearbox or motor-driven, it gives the grower control over the environment in the polytunnel.
Opening the side vents allows air to flow throughout the tunnel reducing hot spots in summer. Closing them during cooler months reduces heat loss and encourages the grower
to bring on plants earlier in the year.
Side vents are designed work in conjunction with open doors and/or roof ventilation, allowing full circulation through the tunnel.
- Timber Base Rails
- Timber Side Rails
- Timber Battens
- Full Depth net with PVC skirt
- Draft Panels
- Manual Gearbox
- Aluminium Curtain Tube with Keder Slot
- Wind-Up PVC Curtain with double Keder
This is our professional range side vent with a manual gearbox operating the internal roll-up PVC screen. This system is available for polytunnels with timber side rails. The PVC screen and exterior netting are battened on to the side and base rails using wooden laths. The netting comes complete with a solid draft-proof skirt, draft panels are also fitted to the mesh where the curtain ends to minimise the cold air entering the tunnel. The PVC Screen fits inside the aluminium drive tube using a Keder bead and is raised or lowered with a manual gearbox. (An automation option is available)
We only offer sliding doors on our commercial tunnels. Over the years we have learned that doors on polytunnels work better and last longer if they slide rather than swing. We offer 2 models; a low-cost timber framed, clad in polythene and our new heavy duty aluminium frame, clad with PVC. Both versions come with our aluminium profile sliding track and 4-wheel roller carriages.
Low-cost Timber Doors
- 3” x 2” timber with fixing battons
- Polythene cover
- Nail plate joints
- NP door furniture Door shoes fixing to the posts, drop bolt at the back of the door, door catch, small channel to hold the together when shut.
Heavy Duty Aluminium

- NP Designed door furniture, Door shoes to fix to the door posts, drop bolt at the rear of the door, full length channel section to form a seal between the doors, door catch.
Louvres are easily fitted to the ends of our structures. They can be used in conjunction with doors and the configuration can vary, depending on the size of your structure.
Louvre measurement: 0.79m x 2.12m.
Actual ‘opening’ size: 0.8m x 2.15m.
Ventilation Louvres - Pull Cord (Gable end instead of a door)
These feature our unique 3 positional hinge which locks the louvre in place. This allows the louvre to be set in the fully open position, (90°) 1/2 open (45°) or closed.
These can either be single row or a double row (as above) for extra ventilation.
Ventilation Louvres - Rack and Pinion (Above the door)
These louvres feature a rack and pinion system for opening, controlled by a gearbox with winding handle. The rack and pinion louvres are fully adjustable, not just limited to the three positions like the pull cord louvres.
It may seem like an obvious statement, but the more steel in the structure, the stronger it is. How much steel you need can depend heavily on the prevailing weather in your area. You can use the maps and tables included in this brochure (page 6) to check your average wind speed and snow load. This will help you to determine which kind of crop bar hangers you should choose; the “Inverted V” for lighter weather loading, or the sturdier “W-Hangers” for heavier weather loading, load bearing apparatus and crop support.
Formed from 50mm and 32mm diameter, Armour-guard coated steel tubing, our crop bars and hangers are just as strong and durable as the hoops they service. Not only do they pin the hoops together, they prevent lateral movement and joint loosening. When fitted with “W-Hangers”, they’re strong enough to carry direct loading. This is often seen in retail locations where large numbers of hanging baskets or planters are to be displayed. Crop bars also form the backbone of vital irrigation and air circulation systems as they are able to carry the additional load of water pipes, heaters and fans.
Our crop bars are just another reason why Northern Polytunnels produce the most robust tunnels on the market, specifically designed to stand up to the worst that the British weather can throw at them.
V Hangers - Sufficient throughout most of the UK
W Hangers - Used in more extreme locations on wider tunnels
These roof air extraction fans have revolutionised the way that polytunnels can be ventilated. These fans extract heat from the roof space of the greenhouse at its highest point. Which, in turn, draws cooler, fresher air in from the doors or side vents creating air movement in the structure. The 240v fans can be connected to either a simple on off switch, one of our fan controllers or a climate computer.
Click on the image to visit the Roof Fan page
The number of fans required depends upon the volume of warm air you want to expel and how quickly you want to expel it. As a general guide we would recommend a maximum of one fan for every 350m³ of air space – this would allow up to 13 air changes per hour. Typically, one fan would be required for every 35ft to 80ft of polytunnel, depending on the width, height, and existing ventilation systems. For a 30ft (9.14m) wide polytunnel this would be approx. 1 fan for every 36ft (11m) length of polytunnel. Therefore, a 30ft wide x 110ft long polytunnel would require a maximum of 3 fans. Even if only a single fan was installed you would still feel a significant difference as you would still achieve 4-5 complete air changes per hour.

Optimal ventilation is vital as it plays a significant role in the cultivation of crops. Effective air circulation not only supports but drives crop growth and gives the grower complete control over the climate inside the tunnel. Mould and fungal diseases thrive on poor ventilation, which is why proper air flow is so important. It’s not all about the heat. On a humid and sunny day, when the temperature inside the greenhouse rises excessively, it’s important to open the vents to avoid overheating and to spread that cooler air evenly throughout the tunnel. This can be achieved using circulation fans throughout the structure.
