Polytunnels and wind

[Northern Polytunnels]

Need to put up a structure this summer to keep our machinery in the dry and to put some straw bales in. Can't justify a steel building cost wise, so now looking at a polytunnel. How do they stand up to high winds? We're at 1000ft and quite exposed. Looking at a 30ft x 40ft. We looked at the Mcgreggor tunnels at the NSA show in Malvern and thought they looked far sturdier and better put together than all the other manufacturers there. Just wondering what experiences other had with them.

Everyones comments are bob on, I would just add FOUNDATIONS to the mix. There is no substitute for strong level foundations. Concrete if you can (look at planning permission) and go for a thicker diameter, galvanised foundation tube. Container Canopy may also be a good option (if you have containers) as this will give you more height than even a high-sided polytunnel.

Thank you for confirming it wasn’t Northern Polytunnels that you ordered your polythene from, but a totally separate company called LBS. You had us scratching our heads for a while there.

LBS and Northern Polytunnels have not been within the same group of companies for a number of years now. As such, due to data protection, we are unable to see your trading history with them. This is a public forum and false statements can be damaging to a business, we appreciate your right to “warn others of a rubbish product” but ensure you are naming the correct company and product. That being said, we would appreciate it if you would remove the false statements about Northern Polytunnels.

Your comment, “Guarantee is not worth the paper it is printed on” is also puzzling. We cannot comment specifically about your experience with LBS as we simply do not have the details, we would recommend that you contact them directly to resolve your issues.

Northern Polytunnels supply approximately 61,750m of Visqueen polythene to all areas of the UK and Europe per annum, and we offer a 7 year guarantee against manufacturing defects and early UV degredation. We have supplied it to the Arctic Circle, the Scottish Isles and we have 120 + polytunnels in the Falkland Islands. From what they tell us, it gets more than a little blustery down there and in 30 years we have had no complaints regarding the strength of our polythene or our structures. On the contrary, we are the only supplier to that part of the world. From our experience, we believe our polythene is by far the most superior of quality and strength.

Before you start accusing false statements actually READ what I said by your own admission it is Visqueen you use for your polytunnels and its Visqueen who have been out on site taking samples, photo's and recording roll numbers. Nothing false about the statement made.

I don't want to derail a thread that's off in a different direction but while you're here can I ask - Do you still supply the rubber strips that fasten the cover on?. I can't see them on your website. I probably have the original paperwork somewhere with the model name but without rooting for it, it's got a groove in the metal & you poke a rubber strip into the groove with a flat tool. (!)

We have PVC infills - https://www.northernpolytunnels.co.uk/pvc-infills.html which work in the same way. How old is your tunnel?

At a guess, about 6-7 years. It's called a "super" something & the small length of strip we had left says "V-grip" on it, if that helps.

Ah the Super 8, we do have some of those rubber infills in stock. Not on the website as we no longer sell the Super 8 polytunnel, but if you give us a call we can sort you out. The strips come in 1.5m long, can give you them for £1.00 per strip plus delivery.

That would be great, thanks.

Hi All,
Did your polytunnels survive last weeks storms? especially in Ireland. I have just bought an ex mushroom Tunnel for weanigs. (Just Hoops) My plan is 4ft wall, 2 ft wind break & then plastic roof.
Site does not have much cover & is @1000ft. My question is - do I completly cover the ends & hope the 2ft of wind break on sides is enough ventilation? Thanks in advance, j

Edit: Tunnel is for my 9 month old Whitehead Weanlings not weanigs!
