Covering a Polytunnel using Aluminium Base Rails

The use of Base Rails is a very popular option for covering a polytunnel. Premier Polytunnels offer an Aluminium Base Rail option, doing away with the need for digging a trench and allow for cover tensioning. This video demonstrates how to fit your polythene cover to Aluminium Base Rails.
Also see our in-depth video, ‘Fitting a Polytunnel Cover using Base Rails’, here: • Fitting a Polytunnel C...
Covering to Aluminium Base Rails - Roll the cover out down one side of the polytunnel and, holding the edge of the sheet, pull over the framework. Check the cover is central down the length and width of the tunnel - do not worry if the cover does not reach the floor on the ends of the polytunnel.
Starting at one end of the polytunnel, fix the polythene to the timber door frame lintel using a timber batten and nails. Pull the cover tight along the length and fix to the timber lintel at the opposite end.
Down one side of the polytunnel, starting in the middle, lightly tension the polythene cover down to the aluminium rails. Carefully fix in place using grey PVC 'U' profiles - these 'U' profiles should be inserted into the slot on the aluminium. Continue this process out to each end of the polytunnel.
Repeat this process on the opposite side of the tunnel - again, only lightly tension the cover down to the aluminium.
At each corner, cut the polythene in line with the end hoop below the aluminium rails. Pull the excess around the end hoop to the door frame, twisting your wrist to create pleats in the cover. Fix the cover to the door frame using timber batten - the batten should be fixed tight up to the rebate batten.
Repeat this process at the opposite end.
At each corner, lightly tension the cover down to the aluminium rails from the hoop to the door post, carefully fixing with a grey PVC 'U' profile.
Insert a grey PVC 'T' profiles into all 'U' profiles.
Once the cover is entirely fixed around all the aluminium rails and door frames, loosen the Base Rails fixings and lower the rails back to their original position - this will add extra tension to the cover. Re-tighten and secure all fixings with a self drill screw.
It is important to now fix all hoops to foundation tubes using self drill screws.
Taking care, trim off any excess around the door frames.

I am planning to get a poly tunnel next year so these videos are very helpful. My only complaint is that they don't come out often enough. I have been subbed for ages but rarely get any notifications. Do you have any pamphlets or catalogues about your products?

Hello,
Thank you for your comment.
It's great to hear that you are planning on getting a polytunnel next year. You will love it!
We don't film videos often - We have a lot of construction videos which were filmed and uploaded 6 years ago, and these videos are still relevant today.
We do certainly have a brochure which we can pop in the post for you - Please e-mail your name and address to [e-mail]
Kind regards,
Premier Polytunnels
