Hi all can anyone tell me the best place to get plastic for a new polytunnel?

Hi

Depending on what type of plastic you are after,they sell it on ebay

Make sure you buy one that is UV rated, or it won't last very long.

There are lots of suppliers on-line, and this thread may help

I've used this for our cover...

http://www.generationhireandsale.co.uk/sheeting.php

It only comes in 2m or 3m wide rolls, but it only took three 'strips' of the 2m wide to cover our 'poly.



Picture taken when the doors were unfinished this summer 

Where the over lap was, we used flat timber, and 'sandwiched' the overlap with screws, giving even more strength to the frame. 

But I guess this current weather warning of high (possible 70mph gusts) winds will be the real test.

How did it work out , because the link says only 50% light transmission?

It's not UV stabilised either

Hi mum, the cover we used was the clear one (Triflex), it has the 70% light transmission not like the white cover which has a reduced light transmission rating.

As for being UV stablised, all but one other plotter has used this kind of cover and it has lasted them 8-10 years, that's longer than what them 'proper' poly covers last.
