    I'm going to look into the cost of getting a skim coat done, although I might be urinating contrary to the air movement on that one- I don't think it's common practise up here. Just so I can budget for it, it wouod be interesting to hear what people have paid for this- PM if you prefer. Is a m2 price the standard,p? I'd imagine smaller rooms and vaulted ceilings (both of which I have!) would bump the cost up. If it turns out not to be too expensive, that probably means I can get slightly sloppier with my plasterboarding

    I just used ordinary nail gun nails on my counterbattens, but I used long screws on the battens. This was because I wanted to fix right through to the stud, and you can feel whether a screw has bitten or not, plus a 90mm nail wouldn't have been long enough.

    It never really occured to me to do it landscape. Don't you end up needing a lot more supports on the board joins?
  4. Crofter
    Thanks Nick, makes perfect sense now. So a shorter joint with some added support, rather than a long joint that lines us with the battens. It will be easier to handle two square bits as well, rather than two long skinny ones. (Confession time- I already broke one board yesterday when I thought I could balance it on my head and carry it up a stepladder. Note to self, no you cannot).

    Erm, not sure I'm following you on this one. How many bits am I cutting the board in to?? If I cut lengthways, then there is no 'top' and 'bottom' bit, just a left and right.
  6. Crofter
    Here we go... the next bit of pb on the left has to be cut to fit round the beam... so vertically or horizontally? I have already planned the boarding of the ceiling so as to maximise the number of full boards, but there are three each side that clash with the beams.
  7. Crofter
    Another wee question: On the vaulted ceiling, there are exposed beams that the boards will have to be cut around. In some places the beam is at the edge of the board and I will cut a small chunk out, all good, but other beams land smack bang in the middle of a board. So I presume my options are: - split a board longways up the middle, and fit it around the beam. Pros: no additional battens needed. Cons: full length cut edge joint. - split the board across its width and put one part above and one below the beam. Pros: shorter total joint length. Cons: Will need extra battens to support it What would you chaps do? And don't say "make sure the beams are all on 1200 centres", it's a bit late for that!

    Agree that management of the nearby trees is going to be much easier and more effective. You could always consider the rebuildability of the hut... lash beams together Polynesian-boat-style so that they absorb the flex and gracefully make their way to ground without breaking?

    Keep it under 30m2 and without obvious overnighting accommodation and you won't need a warrant. Likewise if you make it portable/moveable in up to two sections, which is the route i've gone down. Going the portable route lets you make it pretty big (6x18m exc roof overhangs) and obviously you can't have a slab, you'd have to go for a suspended floor. I would think that for a garden room that spends a lot of time empty, the main consideration should be keeping it free of damp, rather than worrying about energy consumption. So I would be tempted to make it both well insulated and well ventilated, and maybe not go down the airtightness route, unless you are going to go the whole hog and fit MVHR. Hmmm... sub 30m2, straw bale walls, design it around whatever windows you can get on Fleabay/Gumtree, little woodburner, optional single room MVHR unit to keep it sweet.

    There's a great deal of choice on this. Fortunately all the vital statistics are available on the BBA certificates (don't consider any membrane which doesn't give you the cert number). I didn't have a spec to meet but made a choice based on availability, price, and getting what seemed like a good product for the money. I have an exposed site and a slow build so the stuff needed to be able to last as the only weathertight layer for several months. I used Glidevale Protect TF200 on the walls, and for the roof I went with Cromar Vent 3 Pro, which has not let a drop in since I installed it last summer. The wall membrane was not quite so impressive and there was a rip with consequent leakage at the SW corner of the building, but patching it with another layer solved that problem.

    Use a gun and then you can go back to the it after several weeks and it will still work. OK you have to pay £7 for the gun but consider that an investment. I've not had to throw out any part used disposable cans since.

    Windows looking good- you've been busy! I've likewise had mixed results with the foam guns. I just buy them at £7 a pop from eBay. The gun grade foam is about £3.50 a can from Toolstation so just as cheap as the single use version. I'm on my third gun now and this one seems to be a keeper, after I ruined the first two. The trick I do now is to give the nozzle a little squirt of foam solvent to keep it clear after each use, but I don't ever unscrew the can unless changing to a fresh one immediately. Oh and glad to know I'm not the only skip raider on the forum! The shuttering ply I used for my piers came from a skip...

    Another question... where I have to butt two boards together, e.g. on walls that have vaulted ceilings above them, is it better to leave say a 5mm gap for easier filling, or should I just sit them flush?
  14. Crofter
    Well in the absence of any other info, I think I will just minimise joints even if this means one or two joins end up lining up with openings. The sheets are fixed to battens which are separated from the studs by a layer of 50mm PIR, so I think there is scope for slight movement in the frame without that translating to cracks on the sheets. Certainly I have a lot more fixings holding the sheets to the battens than I have holding the battens to the studs, and those are long 150mm screws with a bit of flex in them. Could just be wishful thinking. No opinions on whether to leave a gap at the bottom or not?

    Could he dig a ditch and divert the burn instead?

    If the ground is flat enough to flood, there's probably not enough head for a hydro.

    In my continuing search for an answer on this, Google throws up this suggestion: https://www.familyhandyman.com/drywall/taping/drywall-butt-joints-made-easy/view-all Basically you force the board into a taper by screwing down onto a thinner batten. I guess this could work but it seems a bit of a bodge.
  18. Crofter
    Possibly. Maybe need some fine sandpaper to smooth off the cut edge of the paper. But I'm hoping this is a solved problem. I can't be the first person to wonder how to do this!
  19. Crofter
    The choice is jump to the other side, leaving a bit needing patched, or end up with a board edge lined up with the opening, risking cracks. It has to be in one or the other. They're full size sheets.
  20. Crofter
    Well I did say majority of people. Not everyone is mortgage free.

    Tapered is the standard around here. Most people just tape and fill, and don't bother with a skim coat. It simply isn't possible to avoid some cut-to-taper joints. E.g. today I was boarding around a window that's 1800 wide. So each side has a board with a cut out, and the middle is a piece 600 wide. That piece can obviously only have one edge tapered. Then carrying on along the wall, the next opening will be on a board edge- hence my question about whether to cut a board in half lengthways to avoid this (this is what i did for the sheathing). If I continue without a half width board, I'll end up with a tapered edge at the doorway... but I guess I could just fill that?? Not ideal but it looks like I have to compromise somewhere.
  22. Crofter
    We've been through this on the forum before. For the majority of people, energy prices are an insignificant outgoing compared to mortgage payments.
  23. Crofter
    Having started plasterboarding today I've realised I have some fairly basic questions. I understand it's good practice to avoid lining up board edges with the edges of openings- much as you would do with the frame sheathing. But I can't do this unless I cut a board in half lengthways. Is it really a good idea to add an extra floor to ceiling butt joint (and a messy cut edge meets tapered edge joint, at that) just to avoid having a tiny joint above a door?? Secondly, how important is it to leave a gap between the boards and the floor? I get the point where you have an old house with a potentially damp concrete floor, but this is a suspended timber floor. Third, any tips on getting a good finish in places where I am joining cut boards, or cut boards meeting taper edge?
  24. Crofter
    Another plasterboard/window detail question... Where the plasterboard meets the window opening, I was going to have a feather edge there. Will this leave too much filling to be done at the corner? The alternative is to cut the window opening out of the board and then put new battens in for a board join slightly further over.

    I once stayed for a few days in a self built 'eco house' where thr south facing conservatory had a rammed earth brick wall separating it from the rest of the house. The conservatory had louvred opening windows to help remove excess heat. The idea was that the bricks would heat up through the day and then slowly release that heat into the main body of the house. I only stayed there for a few days and it was snowing so can't really report how well it worked. Especially as the owners made us sleep in a tin shed outside rather than in the house itself. They were a bit weird. Another thought: if you start roofing over your conservatory, it becomes part of the house according to building regs. So even though you are reducing energy loss, you might find that suddenly you have to make big changes to the glazed area and insulation to keep the whole house compliant. Apologies if you are already ahead of me on this one. Third thought: don't put PV *inside* a conservatory! You will lose a percentage of the energy as it passes through the glass. Maybe roof mount them to give extra shading without losing the 'conservatory' status?
