Heavy Duty Polytunnel

Size: 12ft x 24ft x 8ft


This Heavy Duty Polytunnel will help you make the most of the British seasons, encouraging and promoting higher temperatures and humidity in it's very own micro-climate due to the heat exchange being very efficient. At a spacious 12ft W x 24ft L x 8ft H, you'll have ample room to grow and maintain flowers, plants, fruits and vegetables.

This Polytunnel Greenhouse is perfect for allotments, large gardens, fields, smallholdings, school gardens, communal gardens or plant nurseries.

An allotment polytunnel could be a great investment.

As the Polytunnel isn't a permanent structure, it can be moved and assembled easily without the need of planning permission.

With a Polytunnel, out of season / climate plants have a better fighting chance at withstanding the unpredictable nature of British weather.

You'll be able to better control the conditions in which your selected plants thrive best - temperature control, ventilation and irrigation begin to become a reality for the keen grower.

You can also keep your growing efforts safer from excessive heat, sunlight, wind, cold, rain and scavenger pests.


Highly efficient heat transfer:

We like to use and get to know any product that we sell, so we put one of these Polytunnels up on our farm to see just how good it is, and we weren't disappointed. We popped a temperature / humidity sensor in the Polytunnel on an average overcast spring day, with a few breaks in the cloud, giving us a temperature differential of nearly 10 degrees in 12 minutes.

Powder Coated Heavy Duty Steel Frame:

Powder coated steel helps to prevent corrosion and keep your Polytunnel lasting a long life. The poles are heavy duty at 1.5mm thick.

Removable Front & Rear Panels:

Control the airflow to your Polytunnel with the option of attaching or detaching the front & rear panels.

The front panel features Zips and Velcro holders, so you get the best of both quickly.

Cylindrical Roof:

Thanks to the cylindrical shape, water / snow become less of an issue and you don't have to worry about your Polytunnel buckling under heavy stagnating water / snow.

Additional Anchoring Included:

We understand that some areas are more prone to high winds than others, which is why we include additional anchorage for your Polytunnel. 4 heavy duty ground stakes and 4 complete ratchet systems are included to help keep your shelter firmly in place, but we advise dismantling your shelter if severe weather is anticipated.

Heavy Duty Woven Fabric:

Our Polytunnels are built to last - lightweight polythene is effective but also very flimsy.

Our polytunnel plastic is superior in quality - we provide a high strength woven thread, UV treated 200gsm Polyurethane Polytunnel Cover which is much better suited and will long outlive a lightweight polythene cover.

Cover: 200G/M2 PE COVER, 3% UV and 100% waterproof.
