Thermal Anti Drip - 720 gauge Upgrade

-

£0.00

Close

Here at Premier Polytunnels we sell a clear Thermal Anti Drip polythene cover as standard. This is a 720 gauge/180 micron polythene film with a 5-year warranty against UV degradation and is the preferred cover of UK growers - supplied as standard with our Dream Polytunnel Package.

Our Thermal Anti Drip polythene is the UK's first polytunnel cover to include NEW 5-layer co-extrusion technology. This 5-layer, 21st Century technology allows special chemical additives within the polythene to be divided more evenly throughout the layers, therefore reducing the effect of each additive upon the others and making for a more efficient polytunnel cover. These special additives help to greatly reduce many fungal and bacterial diseases that can damage plants.

The air inside a polytunnel has a high moisture content, causing water to evaporate and form droplets on the inside of the cover. Anti Drip additives within the polythene film prevent large droplets forming and dropping back onto the plants, causing damage and disease to them.

The Thermal effect of this polytunnel cover prevents heat radiation being lost from the polytunnel, therefore maintaining a higher foliage temperature and drier plants, and leading to lower heating costs.

This film uses mineral additives to diffuse the light entering the polytunnel, ensuring that some light will make its way into the central and more shaded areas of the plants.

The film also includes Anti Dust additives on the top/outside layer, making it more difficult for dust to remain on the polythene and making it easier for the wind, rain, and your cleaning efforts to remove any accumulated dust from the polytunnel.

Premier Upgrade

-

£135.00

Close

Although our 12ft wide standard polytunnel has unmatched stability, for those sites exposed to extreme weather conditions why not choose to Premier Upgrade your polytunnel to include a larger diameter of hoop (38mm).

Anti Hot Spot Tape Kit

-

£0.00

Close

This self-adhesive foam tape is a must on any polytunnel – We cannot recommend it highly enough. The tape is placed on the metal framework wherever the cover comes into contact, helping to prolong the life of the polythene sheet as it prevents cover degradation from friction and the built up heat on the framework. The smooth surface of the tape allows the cover to be pulled easily over the framework without catching or tearing during construction.

Anchor Plate Kit (for soil base)

-

£0.00

Close

FOR FIXING POLYTUNNELS INTO A SOIL BASE.

Originally designed and developed by our very own polytunnel specialist, anchor plates have been successfully used for many years and have proven to be a much simpler method of securing polytunnels into the ground than the use of concrete. These plates clamp to the base of each foundation tube in a 16-inch hole, which would be dug just as for concreting. When earth is compacted back over the plates, this prevents the polytunnel framework from lifting or sinking, even in the most severe weather conditions.

Anchor plates MUST be used when purchasing base rails and are advisable to be used even when trenching the polythene cover in soil as this prevents the framework from sinking and the cover becoming loose.

Anchor plates have been updated at Premier Polytunnels to include an offset hole to allow easier fitting when the foundation tube cannot be placed central in the hole, for example, when avoiding walls, paths, and underground obstruction.

Crop Bar Kit

-

£0.00

Close

These galvanised steel bars are placed horizontally across each of the intermediate polytunnel hoops above head height. They can be used to support hanging baskets, canes, shade net, lighting, irrigation, and many other uses. A further beneficial side effect of crop bars is added strength and stability to the polytunnel structure in extreme weather conditions, particularly on blustery and exposed sites.

Triple Ridge Kit

-

£88.00

Close

These extra ridge bars are placed on each side of the polytunnel's curved roof and run down the full length of the tunnel, exactly the same as the centre ridge which is supplied as standard. This Triple Ridge option adds further longitudinal strength to the structure. These side ridge bars are also suitable to be used for supporting hanging baskets, canes, etc, therefore positioning the baskets over the growing area and out of the way of paths.

These extra ridge bars can be positioned to suit your individual requirements, such as to avoid Crop Bars.

Storm Strengthening Kit

-

£16.00

Close

The weakest point of a polytunnel hoop is a joint. On any polytunnel that deforms in extreme weather conditions, the first point of failure is a hoop joint. Collars bolt into position over each joint doubling the thickness of the hoop, giving added strength and peace of mind.

Timber Base Rail Kit

-

£0.00

Close

A timber base rail simply clamps around the base of the polytunnel framework, therefore doing away with the need for digging a trench and allowing the polythene cover to be simply fixed to this rail. Base rails are adjustable to allow for cover tensioning.

Anchor Plates or Base Plates are a MUST when using this method of fixing to prevent the polytunnel framework from lifting.

Timber base rails are pressure treated with a wood preserver to protect against rot and the cover is fixed simply by using timber battens and nails.

Timber Side Rail Kit (Left side)

-

£117.00

Close

Timber side rails are exactly the same as base rails, but these rails are placed around the polytunnel framework at the top of the straight sides. This allows for net ventilation, which is supplied by Premier Polytunnels, to be placed between the base rail and the side rail, with the main polythene cover stopping at the side rail. Side rails can be fitted along one side only or both sides.

Timber side rails are pressure treated with a wood preserver to protect against rot and the cover is fixed simply by using timber battens and nails.

Aluminium Side Rail Kit (Left side)

-

£238.00

Close

Aluminium side rails are exactly the same as aluminium base rails, but these rails are placed around the polytunnel frame at the top of the straight sides. This allows for net ventilation (supplied by Premier Polytunnels) to be placed between the side rail and the ground/base rail, with the main polythene cover stopping at the side rail.

The polythene and net are trapped into the aluminium with PVC infills which can be easily removed and reused should the polythene need re-adjusting or when the time comes to re-cover the polytunnel.

Ventilation Screen Kit (Left side)

-

£203.00

Close

When nature needs a little help, a polythene ventilation screen puts you in control, allowing you to create the environment which best suits your plants all year round.

The side ventilation (incorporated in our Side Rail kits) sometimes used on a polytunnel is not always required, especially in the colder months. To protect young or tender plants from frost damage or to maintain heat from an artificial source, it is often necessary to screen off the net ventilation.

Here at Premier Polytunnels we have designed a simple to use polythene screen which is rolled down over the side ventilation net. The ventilation can be screened off fully or partially, or can be left completely open depending on the amount of ventilation required.

A low ratio gearbox allows you to roll the screen up or down in seconds with the use of a simple handle that requires little effort. Operated from the inside of the polytunnel where the screen runs between the hoops and ventilation net.

This kit is a ventilation screen only, designed to be used in conjunction with a Side Rail kit.

Polytunnel Gutter Kit (Left side)

-

£93.50

Close

Here it is... the solution to collecting rainwater from your polytunnel.

With more than 30 years experience in the horticultural industry, we have used our expertise to bring you a water collection system for your polytunnel.

Designed in-house by our highly skilled and experienced team, and integrated into our polytunnel design, these gutters are designed to be used in conjunction with our timber or aluminium side rails. On aluminium side rails the gutters simply slot into place on either one or both sides of the tunnel. For fitting to timber side rails, a gutter carrier is screwed to the timber rails and the gutters simply slot into place. A stop end slots into the gutter at one end or, if you prefer, you can position the stop end at any point along the gutter and collect water at each end of your tunnel.

Long-lasting and aesthetically pleasing, our polytunnel gutters require no maintenance other than clearing them of debris occasionally.

Collecting rainwater is an easy, cost effective way of ensuring you can always keep watering.

This kit is a polytunnel gutter only, designed to be used in conjunction with a Timber Side Rail kit or our Aluminium Side Rail kit.

Ground Cover Kit

-

£33.00

Close

This black, heavy-duty UVI ground cover acts as an effective weed control with less than 0.5% light transmission, while still allowing water to be easily dispersed through into the ground without collecting in puddles. Premier Polytunnels use 100gm ground cover – 10% thicker than most other ground covers. This ground cover is strong and tear resistant, easy to clean, and has grid lines for accurate pot spacing. The inclusion of UV stabilisers allows for a long effective life.

Overhead Irrigation Kit

-

£59.00

Close

An overhead watering system is a simple and effective method of bringing water to your polytunnel, ensuring that the plants you have tended and nurtured receive just the right amount of water.

It is essential to consider the water SUPPLY and water PRESSURE when irrigating large areas, therefore Premier Polytunnels have used their expertise to design systems that you can rely on.

A polythene pipe fits to the roof of your polytunnel with sprinklers on drop tubes placed at approximately every hoop along the length, ensuring full coverage and avoiding dry spots. The pipe continues down the door post where it is connected to a garden hose.

A single central line is the ideal way to water 12ft wide garden tunnels.
