One of the best features of our new Easy-Build polytunnels are the aluminium base rails and door frames. So why did we decide to use aluminium over timber?

Aluminium V's Timber



Aluminium provides the longest lifespan for your polytunnel. Aluminium is a durable, resilient and strong material, and can last anywhere from 30 years upwards. This makes aluminium a perfect material for use on your polytunnel.


Timber is subject to high levels of deterioration and decay and will need replacing several times over the lifetime of your polytunnel.


Our polytunnels will last a lifetime, therefore, we wanted to use a material that is as strong and durable as the hoops and foundations. Aluminium does initially cost a little more, however, timber will need replacing several times over the lifetime of your polytunnel.

Aesthetically Pleasing

We can't argue that when a polytunnel is new both timber and aluminium looks great. Fast forward a few years when timber has been affected by humidity, moisture and pests and the aluminium is just as clean and shiny as it was on day one... aluminium is the clear winner.


Aluminium door frames and base rails ensure very low levels of maintenance just a wash down with a hosepipe and they are as good as new. Timber door frames and base rails require effort to ensure they are kept looking good.

Fitting The Polythene


Our ‘W-Wire’ polythene securing system simply weaves into the open channel of the aluminium rails & frames, securely trapping the polythene in place.  If you need to redo a section, it’s easily unclipped and can be ‘wiggled’ back in to place in a jiffy, ensuring a tight, neat finish every time!  This is especially useful when pleating the polythene around the door frames. ‘W-Wire’ is the easiest and quickest system on the market and doesn’t require any specialist tools.


For those of you who have previously used timber rails you’ll already know how difficult it is to fasten polythene using wooden laths/battens - trying to pull the polythene tight whilst holding a lath in place, positioning the nails, and finally hammering them home, and all with only one pair of hands. The timber battens may need replacing each time you replace your cover.
