Just bought a 6x3 meter polytunnel off ebay to store softwood nets

Its rubbish. It degrades within a couple of years as its not UV stabilized then splits along the threads. It lasted about 3 years on our exposed site we normally get 5-7 years from the normal visqueen we use.

 

The plastic sheet used on lorry curtainsides is very good but difficult to keep under tension.

 

Roll up tunnel vent is UV stabalised. Not used it but I believe it normally has a 10 year life on the top of a tunnel. It will be expensive but must be stronger than normal tunnel cover. Whether its worth it depends on price difference. I will enquire.

A local garden centre told me they have to be careful what they use now due to lack of fire proofing.

If the public have free range then I would imagine that's a big problem. No general public on the nursery I work for but always a worry. Our thermal screens have fire break lines but I have seen pictures of the devastation a screen fire can cause. Pretty much a new glasshouse needed.

Ist year I was there we had a fire in a home made lighting cabinet. (Built pre CWB I might add) It caught the tunnel plastic above it but was limited to that end of the tunnel. A lot of black smoke apparently but easily put out with a hose.
