100 MPH winds in March.  Once one panel comes out the wind gets inside and tears it apart.

<gulp>

Was that John + Vals? Is there a thread on here telling the story?

I think I should be OK when I bolt the whole kaboosh down. As I wrote the GH is sheltered from most of wind with a fence and very high/thick privets on one side, luckily enough from where the wind direction predominates (to the east) I sacrifice a little morning sun because of this but it's swings and roundabouts give and take etc........

Dramatic isnt it.
The year before last I converted my inherited with the house 6 x 8 greenhouse to twinwall.  It was originally 4mm glass.  Lots of cracks some missing panes.  I ordered 4mm Twinwall.  So I used the tape top and bottom.  I replaced each panel one at a time.  I redid the door.  Wherever possible I used a large sheet, the glass was several sheets in each panel.
Winter, a side panel blew out, that let the wind in and it blew out a roof panel and another side panel.  Next day I fitted extra springs, 8 springs on each long side.  The roof panels tended to bow slightly and that was how the wind got in.  So Ive now fitted timber strips, on the inside to tension and remove the sag in the roof sheets.  This is along the ridge line.
Last winter, not a problem, nothing was damaged.  However the tape was just falling off and was trailing all over.  I removed it.


My greenhouse is screwed down into a solid concrete base made of thick edging blocks.  I did not have the problem that John had.  A lot of that, John admits, was the exposed position.  However, screw it down, tight.  The wood base is not enough, screw it to concrete.  If you do as you say it sounds pretty good to me.

At last!

Finished the glazing..........

Moved in my little trio of tommies and my solitary chilli plant. I'm hoping to start a cuttings regime soon so will quickly fill up my staging with odds and sods. Thanks guys for the advice and the interest.

Onwards and Upwards!

Ahh, I thought about you yesterday.  I read on here, someware, that a good way to protect your GH from wind is to put a dexion frame along both long sides.  Screw it to the GH frame.  Put in end pieces and then a shelf crossbar.  The shelf slats can be removed to give full height when you need it.  The dexion being screwed to the frame strengthens the frame and if you put the slats in over winter it weighs it down.

Picture looks good.  excellent work.

I used 4 sturdy brackets, one on each corner, bolting the base down to the concrete block footings. The frame is well screwed to the base. The GH was in this position for 20 years or so (unbolted)  without toppling in the wind but that was with a full set of glass weighing it down. I think it will be safe now.........

Had to google Dexion :=]  That stuff looks very handy but not cheap, will take me a bit of buttering up of the Missus to extend my gardening budget (again) Could do with some in my shed as it happens...........

I see your chicken is admiring your handiwork. Or does she have an eye on those tomatoes

The girls quite enjoyed using the GH floor as a massive dustbath. Sadly the frolics have now come to an end for them since it's all been glazed. I'm hoping they'll use that soil filled Belfast sink you can see in the background :=]

Guaranteed I'll forget to close the door one day though.............

You will unfortunately, it's an inevitability. When you do it'll be carnage I'm afraid. They eat everything 
Their little beaks are like razors, scything everything off. Bless 

You'll be amazed at just how much you can rear and grow in a greenhouse that size. It opens up all sorts of opportunities that you didn't have before, allowing you to extend your range.

Tell me about it :=] It's filling up already. I already have plans, the choices available are bewildering but I think I'm going to go for chillies, tommies and lemon cucumbers.............
