12ft Wide Polytunnel Range

The 12ft wide garden tunnels offer all the advantages of the smaller 10ft wide and are manufactured to the same high standard using 28mm diameter steel hoops. The extra width allows for the use of a double path system when growing in the ground or central beds, and when using staging or raised beds. 3ft straight sides give an internal space that is lacking nothing in comfort for the user and ample growing space for a variety of plants.

Although our 12ft wide standard polytunnel has unmatched stability, for those sites exposed to extreme weather conditions you can choose to upgrade your polytunnel to include a larger diameter of hoop (38mm). Please phone sales office for details on 01254 820088

All polytunnels are supplied as a complete unit ready for assembly onto a soil base. Our standard garden tunnel kits include ALL of the following:

  • An all-steel framework – made using LARGER diameter hoops than our competitors for extra strength – including foundation tubes, hoops, corner stabilisers, and ridge.
  • Timber door frame and an up-to-2ft 8in WIDE single hinged door at the front with a timber end frame with dummy door at the rear.
  • A NEW TO THE UK 600 gauge/150 micron Thermal Anti Drip polythene cover, with a 4-year warranty against UV degradation.
  • Option to upgrade to the 720 guage cover - See Options
  • A full range of additions are also available and are highly recommended to enable you to customise and enhance your polytunnel to suit the needs of your chosen plants, such as an extra/double end door, crop bars, anti hotspot tape etc. See Options

Please note that the back panel with half net comes as standard. On soil you will require anchor plates and on concrete you will need base plates.

N.B If you, if you choose the Vent Screen Option, you will also need to order a Side Rail Kit. Please also indicate which side the Vent will be going on.

Anti Hot Spot Tape Kit
This self-adhesive foam tape is a must on any polytunnel and is now included as standard – 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. 

38mm Hoop Upgrade


Although the 10 ft wide standard polytunnel has unmatched stability, for those sites exposed to extreme wetaher conditions why not choose to upgrade your polytunnel to include a larger diameter of hoop (38mm) with the Hoop Upgrade option.
