polytunnel cover help

[hypnophil]

I bought a polytunnel in september but with the recent winds it has taken a battering and the door has ripped from the zip, i thought about repairing it but maybe i should just get a better cover now i have the frame.
is is 7 foot wide, 7 foot high and 12 foot long, do any of you guys know the best way to go about this and where to get a cover from? i would prefer a seamless cover. also any advice on constructing a door and measurements of sheeting, the sites i looked at are in metres!!!!

You should be able to buy replacement covers from any of the major polytunnel suppliers - try Fisrt Tunnels or Northern Polytunnels - both have a selection of cover types to choose from. If you give them a call they will also advise on sizes required, and on door construction etc. I have spoken to both these companies before at length and found them both extremely
helpful.
Good luck
