14ft Wide

14ft Wide "EXTREME" Polytunnels

  • For our "Extreme" range of polytunnels, we've used a whopping 50.8mm diameter tubing for the hoops, ridge and corner struts. The steel is high tensile "Z35" grade which is galvanised and has a 1.5mm wall thickness.

  • The foundation tubes use the same diameter 50.8mm galvanised steel tubing..

  • For our 14ft wide "Extreme" range, the polytunnel hoops are spaced at 6ft apart for the most robust 14ft wide polytunnel available.

  • As with all our polytunnels we've made sure there are no weak links and each component is designed to ultimately fulfil it's purpose.

  • The foundation tubes on this range of polytunnels must be concreted into the ground. This ensures the structure is as strong as possible.
    Quite simply, we doubt you'll find anything stronger!

    The "Extreme" polytunnel kit includes:
    • Galvanised foundation tubes for concreting in
    • Galvanised high-strength steel framework
    • Tanalised timber end frames
    • Tanalised timber base rail included
    • Galvanised fittings & fasteners
    • Choice of Clear or Diffused polythene cover
    See below for a more detailed specification.
    Indasol Polythene:

    Our "Extreme" polytunnels are supplied with the latest technology polythene cover: Thermal Heat Barrier (THB) for improved temperature control. Reduces heat build-up on hot days, retains heat at night time. Anti-fog / Anti-condensate (AF) for moisture control. Avoids fog forming on those cold mornings and stops condensation forming as droplets, which can reflect up to 40% of sunlight and can cause spread of fungal diseases.
