What is sad he just forgot to fit the vapour barrier between the rafters and the plasterboard. But plasterboards are precisely cut.

@quattro blood his got hands like leather

[@marksmith2412]

Something I do with plasterboard that I rarely see others doing, after scoring and breaking I'll fold the board then run my rasp over both cut edges at once before separating my piece. Keeps your edges nice and true and saves having to knock off any lumps that might make the board a bit tight.

Great job Robin, I’ve done the 3rd window with the training and the plasterer has started this week and has been commenting on how good the boarding and walls are.

[@ukconstruction]

Top man, I am well pleased that you have been able to put this into practice, have a great week!!!

[@tilepro-uk]

I luv it that you blow the dust away when you slice the plasterboard. That’s exactly what I do. There is too many dust particles throughout the building trade and it’s about minimising what you inhale. When the lights on it you realise just how much a plasterboard actually gives off

[@rich3511]

Pure genius. Thank you so much for passing your skills on to others. Is much appreciated.

[@ittsjaake9055]

I’ll remember this, too many times I’ve been doing similar work with a sliding bevel and roofing square. Cheers Robin

[@SingleTrack66]

It’s how I do it. I always try to get the bottom reveal vertical. It looks really cool if you line it up exactly with the wall below. (Takes some figuring when you actually fit the velux) I also would have packed out behind the plasterboard with insulation or blown some foam around to prevent a cold spot

[@thetessellater9163]

Good point, though foam can be so messy

[@KennyEvansUK]

Under part L you need to defo fill those spaces behind the plasterboard, you can just use Rock wool as it can be classed as a void on the reveal.

[@willber318]

This is why I’m watching this as I need to insulate mine. I’ve foamed around the velux but need to insulate and board them.

[@SingleTrack66]

@@willber318 make sure you do. The top flashing is notorious for causing condensation if it’s not insulated. People tend to think the window is leaking but it’s nearly always because someone didn’t bother or didn’t know how important it was to insulate that wafer thin piece of tin.

Hello Will. None of my business really, I’m a Spark who happens to really like Robin’s work. This is the age old problem, I’ve worked for some terrible companies who don’t care about the standard of work or the time you really need to do it well. If your work is of a good standard (I’m sure it is) don’t hesitate to go out on your own. So many of the trades I know, including myself, took the leap and never looked back. The feeling you have of doing a great job in the time you need outweighs the steady pay packet from a firm. After a while of being recommended, you’ll build up clients and the rates you charge will be much higher. The satisfaction and the higher rates of pay will change your working life and probably your private life too. Whatever you decide, I wish you well and maybe give it some serious thought. All the very best. Gerry.

[@tobybeswick36]

'I've built this roof' well that's always a good start, having a proper joiner build your roofs haha! I'm sure alot of people already know, but a multi tool works well for cutting plasterboard close to the edge instead of the handsaws, you can also cut small width pieces with the multitool that you would struggle with a knife cutting Great job as always, i bet the plasterers love seeing this quality of plasterboarding

[@muirallie]

Great to see splayed instead of the harsh looking square fit. Surely better air flow must help with any potential condensation too.

[@thetessellater9163]

Velux suggests top to be horizontal and bottom reveal vertical, or close to, though not possible on very shallow or very steep roofs.

[@joefowler9600]

If you do the reveals square from the velux, you can fit in some insulation behind all the reveals. Without insulation the reveals are going to be a cold surface and potentially get condensation on them. Also use foil back board.

Interesting way of doing the reveals. I can get a sneaky 25mm of PIR in the reveals if I set it 90 to the window. I guess this can distribute the light a bit better. Hmm may give it a go.

[@joefowler9600]

Thats how i do it also, i think it looks better without a splay and like you say, you can get a bit of insulation behind the reveals.

[@thetessellater9163]

Robin, surely if you had deducted 25mm from the length of the top and bottom pieces [2x12.5mm, assume], that would negate the second part of cutting them to length. The sides fitted, then the top and bottom would be the right size to fit. Or, install the sides first, then measure lengths of top and bottom.

[@Herpitor]

Nope, because they are compound angles. The sides and top/bottom splay outwards from the window to the bottom of the rafters.

Sometimes i use a mixture haha so it might be 87 inches and about 5mm. The only time i use metric is when fitting kitchen's as everything comes in metric sizes so its the only time when metric is the simplest option and even then i still revert back to imperial when cutting fillers and worktops.

I have to disagree with “easy and fast” comment on the title, your correct on your measures but the top and bottom should always be square so the top and bottom can be measured direct from the window edges, then cut to size before once, “rough the sides in” as you said yes but not waste time fitting then removing the top and bottom, then cutting them both twice then re fitting, cut once, fit last, I’d like to see how you overcome cold bridging too?

The u value of the timber is completely irrelevant in this situation, you could argue it’s ok the rest of the roof insulated, a little heat loss in the edge will be fine, and with no vapour control this I asked the roof construction, as with no air flow, and the lack of vapour barrier mould could be a potential.

Use a good breathable roofing membrane, and dont stretch the membrane tight. The proper way to fit a breathable membrane is to let the membrane slight sag between each rafter. You could also double batten the roof for extra airflow below the slates, so a batten directly on top of rafters first, the batten as normal.
