Roger, what is holding that scaffolding down? Presumably when you get a tarp on the type of breezes you get up there will just get underneath it.

Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!
The Orangerie - duff glass-fibre-coating REPAIRED

On that basis Roger why do high sided vehicles get blown over? I hope you are right and with the usual caveat of me knowing nothing I would try and anchor that scaffold if it were me.
Well I sincerely hope you are right.

Actually I think the tarpaulins will rip before the scaffolding takes off. They're supposed to be heavy duty. If they are then I'd hate to use their normal ones.
You do make a good point and I may screw down the orangerie a bit more.
Back on hold again.
I took a closer look at the plastic tarpaulins that I'd planned to use. They were described as 'reinforced' 'heavy duty'. Rubbish. No reinforcement. Thin as anything. No nylon mesh embedded in them. They will rip at the slightest breeze. Damn glad I didn't take off my protection covering this time.
Went back to the company who supplied that clear tarpaulin I had covering my gazebo when the workshop was being done. Bit more expensive but considering what it went through, worth the little bit extra.

So new tarpaulins arrived and Callum been and gone. I stuck my micrometer on the two types of tarpaulins. The first ones measured 3 thou. The second ones (like what I had before) are 15 thou with substantial nylon webbing moulded in.
Lots of reinforcing cat's cradles to give a bit more support
Padding on an scaffolding poking out to try and prevent chafing of the tarpaulin
Top sheet in place. I had to remove it after originally fitting in place as I'd assumed it would be packed so that the longest side unfurled as it were. Sod's Law said it was the other way round.
Aargh...start again
I got it in place by concertina'ing it up at one end. Fixing a rope to the two corners and one dead centre pulling on a couple of eyelets. This latter one proved essential as it prevented the middle part of the tarpaulin from dragging behind the two outer edges and causing fouling on bits and bobs.
Really, really tricky finessing the various tarpaulin sheets as the scaffolders had never built anything like this to accommodate tarpaulins and so many scaffold poles got in the way.
But after a very long day and all on me tod
we have a cover.
And inside...bluddy luxury

That looks just the job Roger. There will be no stopping you now.
I presume the lantern is coming as a kit of parts for assembly in situ then rather than craned into place?

In tree wood or are you buying alloy extrusion?
Either way plenty of fun with compound cuts lol.

Very simple construction. Ridge board and rafters. Having said that it's all new to me. I think I need birdsmouths or some such.
Aluminium extrusion then to go on top for the glass to seal onto. Not sure yet about the hip part but I'm sure SketchUp will tell me.

It looks very nice and toasty Roger.
I’ve been watching the rebuilding of the sailing boat Tally Ho on utube.
He covered the boat with timber frames and tarpaulins by himself which has survived one winter in NW USA. Fascinating programme to watch, he’s back in Cornwall looking at 65’ clear lengths of Douglas Fir specially grown there for boat masts. The trees have most of their branches removed during growth to prevent knots.

So now I'm in the dry (well, sort of...see later) I can crack on. The metal hangers will foul where my upstand is going
(you can see my firring piece as per forum instructions !
Easily rout-outable
I then angled the table saw to match the slope of the firring piece and ripped the first piece of upstand.
This then left me with the other half to go on top of the OSB (because I decided for integrity to run the OSB all the way through from the outer edge to the inside opening.
Corner firring piece to change the slope between sides
and one side nearly OSB'd
But you can see my problem. Water pools all over the place and I'm having to spend a lot of time pushing the water up and down to the next pool and up and down to the next pool. Trouble is that this tarpaulin isn't that good and drips...not impressed. In a strange sort of way, wind is my friend as if there's not much water pooling, the wind will throw up the tarpaulin and discharge the water.
which is fine onto the concrete floor but not onto the OSB which needs to be bone dry to fibreglass.
So I have a few fibreglass questions.
1) Can I fibreglass the roof in stages ?
2) The guttering channel (wood with applied decorative mouldings) will be a last minute job as I can't easily get to it with the scaffolding. Plus I could see the scaffolders standing on it :evil: So what can I do at the edges? Can I just wrap the fibreglass mat over the edge corner or do I have to use those preformed drip edges ?
3) I'm aware that I may need to get some cobalt stuff if the temperature drops too much but anything I should be aware of when using it ?
4) How dry does the OSB have to be ? See below
Back to drips, I discovered that condensation can accumulate on the underside of the tarpaulin so that when a gust comes along, I get rained on !

I'm also starting to think about the rafters for the roof lantern and found endless calculators online. But then :idea: I remembered Mike's house and workshop build and thought 'I bet he has a clever way of doing this by himself) and Lo! So it was .
Thanks Mike :text-bravo:

That was wicked of me, above! Bad Malcolm!
Can you put any constructional timber, 2 x 2 , 3 x 2, 4 x2, anything you've got laying around, above the scaffolding tubes but below the tarp to make smaller squares with less water collected, or even allowing the tarp to straighten out.

Just wondering if a decent sized fan would inflate your plastic bubble and give you a domed roof.
Unlikely I know
Our glass fibre orangery roof is surrounded by parapet wall. There are outlets for rainwater at 3 positions with lead linings formed into chutes into downpipe boxes. makes me wonder if you need a gutter. Just do it with the roof profile.

The roof detail will be similar to this/ The guttering is effectively 'hidden' bar the downpipe
Hey Ho.
Another trip down South and another strong wind. Just got back. In the dark it looks as if the top sheet has been ripped off completely leaving the whole thing exposed. Luckily no rain for now but....
Will have to see what tomorrow brings with daylight. May well have to cut losses and admit defeat for this year.

Oh dear. Regroup and review.
I'm too far away to lend a hand. The only research I can find shows that securing a tarp to a roof is to have fixed battens over the tarp attached somehow either over or through to the structure underneath.

Nothing to regroup and review. I've spent £600 on the scaffolding. Do I get a more heavy duty tarpaulin for the roof or is that throwing good money after bad. Everything is sopping wet. If I shroud the roof stuff now then it's going to get mouldy and manky. If I don't cover it then the wet weather/snow/ice is going to trash it.
Do I simply admit defeat and get the chainsaw out ?
Out of ideas here, bud. Out of ideas.
Heavier duty tarps and stick with it! Don't let the b*stard wind drag you down!

Crikey what a mess to come home to.
I’d go for heavy duty tarps, perhaps two layers depending on the price, lots of guy ropes and an industrial hot air heater to dry the wood out.
Would varnishing them, when dry, work to give some protection?
What about a layer of strong netting over everything??

Regarding the osb, could you slap on some cheap and cheerful polyurethane varnish...or anything that would still allow the fibreglass to still stick ? Those pile of sheets on the floor may not take too long if you used a 9 inch roller on a stick. It's extra expense but at least the water wouldn't be getting soaked in.....as much.

I presume the structure itself is pretty stable, so I'd be inclined to tarp the structure in the first instance with whatever you've got left, but leave some through gaps for draft to ventilate and assist drying. Can you batten any of the tarp down to the top of the structure?
Then I'd try and tarp the scaffolding using the suggestions of the guys above.
That should buy time to consider how to adapt to this situation.

I found my OSB stack was OK with a cheap tarp wrapped round it. When unwrapped but stacked, I found that moisture got in the edges, so it's the edges that need protecting, and the top sheet projects all the rest.

Depends how much money you want to spend, but I would be tempted to look at building an OSB or ply 'wall' around the scaffolding you have - bolt or otherwise fixing the OSB to the scaffold itself. That will take you to 8ft high - a bit like they do around construction sites. Then you only have the same to do on top of the scaffold or tarp the top in some way. If you can reuse the OSB later for other rough jobs such as shuttering etc then so much the better.
A tarp cover in and of itself is going to be a pipper with the winds you have up there, and keeping the rain out is also not simple. You are never going to Heath Robinson a watertight temporary construction from just tarp and scaffolding.
If you do want to give up, work out the cost of a good protective structure, and the cost or starting from scratch and decide then which to go for.... It is a depressing situation now and you are fed-up, but taking a step back and being logical about your options will make you grateful you did when you have had time to think things over.
Just a thought - but is a completed orangery going to be sound if the weather is that bad up there?

Thanks for all the suggestions.
Have now had chance to take a closer look. The 8m x 10m top is trashed. Many of the eyelets pulled out. Notice that the listing says that they are not covered by any warranty. Now there's a surprise. One of the bottom side ones has also had its eyelets ripped out at the bottom but I can live with that.
Having come this far and bearing in mid that the wood OSB is too damp to do anything with until it dries ...so no varnishing etc .... and that I reckon cocooning it in plastic is going to be a recipe for disaster as it's wet now, I'll have one last try and get an even more heavy duty tarpaulin for the roof.
I had thought about something like a cargo net but do recall not having much success as to size. But will revisit. I may well jury rig something up as I have scaffold tubes in the right place to do this and a huge drum of blue cord left (I bought a 500m drum for this project
)
I'm also thinking that the top will have one end unfastened so that any wind has somewhere to escape from hence reduce the loading.
Just damn glad I brought all my tools in before I went away.

Any way to attach timber battens to the scaffold then batten over the tarp so it is sandwiched between battens? Don't need eyelets then and the result should be stronger.
