Poly carbonate green house demolished in wind

Spirit_2

The title says it all. Yesterday my green house took off. I have lost panes and the frame is twisted.

I will start again. I have a brick base and a concrete path and will be looking for a new greenhouse to go on it.

Anyone else had to start again? I will go for toughened glass this time (last greenhouse was second hand from Sil), anything else I should do?

I have 2 polycarbs which have been subject to panels blowing out in strong winds but no significant damage.


It was a few years back but since then I have taken extra precautions to keep the panels intact and touch wood - literally 6ft long 4x2's in this case, I have had no further issues.


Did you have the base bolted down though? That is the first thing you need to do!

The base was bolted down the problem was the house fixing to the base.

There's no doubt greenhouses are better, but £ for £ polytunnels give much more space and are less liable to blow away if built correctly.

However, regardless of what's put up, a decent hedge to filter the wind is very useful, or if you have the money and less time, then a hit & miss fence will do the same job.

Most of the greenhouses round here took off or smashed in the storm in January, our polytunnel was absolutely fine.

I have a polycarbonate GH built it last year and its not in a sheltered spot but survived Winter. I have it screwed into wooden frame quite thick wood which is anchored to ground with 4 metaposts.

I got mine from Primrose its made by Palrams the sheeting isnt twin wall polycarbonate just polycarbonate slotted into frame


This is on my allotment



This is mine

Your allotment looks lovely and a testament to a lot of work and knowledge.

We have bought a rhino greenhouse and will have it erected for us as OH is particularly busy with work at the moment and we want to ensure it is put up properly.

The greenhouse has the same footprint as the blown away one so will be fitted onto the same brick base. The greenhouse site has hedges on three sides. Distances from green house are South (5 feet from hornbeam hedge) The door was at this end. East 30 ft from mixed hedge and West 20 ft from privet hedge. Is there an optimium distance for hedges?

Yes, supposedly somewhere 3 to 5 times the height of the hedge, but I'd not worry too much about that.

Even just 1x the height of my laid elm hedge feels pretty good, compared with the open garden, although there is supposed to be turbulence in that area.

The RHS gives some fairly detailed advice about shelter belts and hedges. After the last few winters, I'm convinced we should be planting more of them, as severe wind seems more common now....and it isn't just my age!

Thanks that is really helpful, not that I can move what we have but may be able to make modifications if needed.
