Will 9mm / 11mm do do you think? Rafters are at 400 centers.... I'm thinking OSB3 would do as well

because that would suffer from the same problem: being lifted UP by the hooley caused by the Wind Trap underneath it . That's what I have renamed the Winter Garden - time spent standing talking to people in the Winter Garden area - I've noticed it's a bit more drafty there than elsewhere.

Part of our roof is outside the heated envelope: open to the fresh air in other words. Have a look at this image. The Durisol wraps the heated envelope: the steels the Winter Garden. Here's a different route view of the same thing. The area on the left is the winter garden. And while there is a window on the plan, we are now not going to have that window: just a plain roof. (Too much solar gain and too much of a Right Royal pain in the Botticelli.) The strange hatching on the roof indicates solar PV -being fitted tomorrow. Woohoo Hoo. Now that we have decided to fit tiles the left hand area of the roof, it occurs to me that the underneath of the tiles will need to be boarded. otherwise the tiles will just be blown off their battens because the wind catches that corner of the house quite a lot. Question. What with? OSB3? Marine ply? WBP? Plasterboard, Caba Board? Any ideas ?

Pleb? We'll I'm not an aristo, so that makes me a plebeian self builder too. What makes it easier? It goes click. Watch the threads about Nulok: I'll be adding to them by the weekend. As I say above, betcha can't wait, eh? Ian

Jesus, Ed....He'd be a walking safety nightmare. ? Couldn't work it this time...... not like the Haldane Fisher driver. After 10:30 here, the sea breeze kicks in, so it could be a lot worse.

Monday morning 0900 sharp it arrived. Superb shipping company: they range me twice to confirm they were arriving. A cheerful Brummie driver (well .... Halesowen is that Brum?) told me that he hadn't had a site H+S briefing for many years. How long did that take? 30 seconds tops. I write this post as a DIYer and a self-builder. I'm in the middle of the full-on DIY experience, and that's why I chose Nulok. I dunno about where you are , but round here, ya jus' can't get the staff guv. It looks as if I might be able to manage it on my own . But then again..... The Delivery Note shows that the all up weight if the delivery was 2.7 tonnes. Imagine my delight then to have to handball it all off the side of the road myself. DIY can be a bit of a bastard sometimes. I have a trailer onto which we should have been able to simply slide the load off the wagon . But I was so exhausted on Sunday night, I didn't unload the last load from the trailer . That'll learn me, wunnit? 5.4 tonnes later (once onto the trailer, once off, 2 lots of 2.7) Can't take a joke? Shouldn'a started this self build should I? A decent Poldark-sweat later (Demelza would have swooned), I had both earned a sherbet, and the further hearty dislike of neighbours who had to slow down to drive past the load sitting in the road. Funny how the bin lorry could get past nay borra Jimmie ( he's Welsh) Up yours too pal. So, unvarnished here's some piccies. I'll be tekin' it slow (back hurts a bit) and posting my Laurel and Hardy-esque progress . Well just Laurel..... That's half the load(ish) for 88 square meters Here's the battens which are metal One pack of tiles is about 1 square meter. Each tile is 400 by 400. The tiles are supported by metal channels which sit either side of it. I hope to have recruited a young lad (lad was previously autocorrected to lady: I can wish) to give me a hand. But more of this later. Bettcha can't wait can ya?

Welcome. Here is what you need. Ian

My personal trainer says that I have a ' resting musculature ' Debbie says ummm......?

Listen pal, wimmin are queueing up in the lane to admire my rippling torso , just like that bit-part bloke in Poldark.

@PeterW, I am not cool, I am not a dude...

I know I am going to get the blame for this. And it is almost certainly going to make it rain for a month. I've had enough of squinting and the forecast is good for the rest of the week; and I'm on the roof . All that highly reflective foil..... So I'm buying some sunglasses. I don't need to look good (or cool even), but I don't need a namby pamby pair of beach shades. I don't need a hard-man aviator look either (although deep down I am a hard aviator Tom Cruise type - but taller, much taller , .... and more handsome) Advice?

Remember your wet T shirt. And video it.

I'm planning to incorporate bat boxes in our Winter Garden roof space. Hopefully Swifts will move in: that would be brilliant. The swallows are already doing close inspections; Sid the Tom Cat is sitting on the scaffolding, licking his lips. And I have found that creating hibernaculae for GCNs much easier than I thought. Anything to keep the little darlings out of the kitchen each time it's warm and raining. We found one (dead) in the cup holder of the back seat in our car. Debbie had been looking at me accusingly - You need a shower dear. - Clearly it had been cooked by the recent weather. How the Hell does a GCN get into a car? Rare? I think not.

Dare not look.....

Ooooooohhhhh hooooo, Ahhhm on ma way hen!

Have you got a few litres of the stuff..... I need a whiff or two to get over my trauma.....

Yeah, well, I didn't expect sympathy. But even a smidge would have been nice. Photo? Its all in the washing machine: but the scaff is full of it.

Treated myself to a decent pair of work trousers from local work-wear shop. At last my knee pads stay where they are put. (The Aldi version of the trousers allows the pads to float free: kneeling meant swearing ☹️ ) Up on the scaffolding, while screwing it onto the gun, a tube of foam decides to dump it's contents on my lap and the scaffolding boards. I slip on the wet foam , and sit in it. OK, calm down at the back now please. Anyone know how to get dried foam out of my knickers, my watch strap, my hands, my watch face, my work boots, my socks, my trousers. From now on... if foaming, I'm changing to the Aldi trousers. Never mind my knees.

Hier sind viele deusche Kuchen zu kaufen. Ja, und dazu billig. Muss nur ein bischen Geduld haben...... MfG Ian

@newhome, I did discuss this with Mr Stevenson. He says he will look into providing CC payment. I drew his attention to BuldHub, and hopefully he will have a look at this thread. Ian

Yes. You have me interested in your thoughts about the integrated solar tiles...... I understand that they are wired in series : but I may be wrong. My site has a little bit of shading for part of the year, and I'm not keen on the one-off-all-off feature that goes with in series wiring.....

3.68 kWp, Yes, Just enough for self consumption - since FIT appears to be a waste of money. My thinking starts at what I think might be considered by some as the 'wrong end' of the stick. I can probably make a good guess at the amount of electricity we are likely to need in kW hours: kWh/a : lets say for argument 3000 kWh. My question is - Given that I want to avoid exporting power to the grid; How little capacity should I install to assure the optimum supply for self consumption?

Tell me more....

Building on @Stones and @ProDave 's lead (pun accidental and innocent) here, it seems that we should put in just enough PV to consume for ourselves. And if, in the same thread , @AndyT agrees as well @JSHarris, you have to have a really good reason to do something different. Next question. How much PV is just enough? Is the calculation as simple as adding up all the likely kWh per annum consumption, and comparing that with the likely kWh the PV system will produce? There will be days when we produce far more than we can consume, and others when we can't produce enough. It'd be good if we could switch panels on and off at will - bit like varying the pitch of a propeller according to need - use all our panels in winter and switch half off during summer. But then that'd be expensive too.
