Wouldn’t all your rooms get 200mm smaller ok in your case, as you have the land, but smaller sites wouldn’t want to lose that much floor area. Your suggestion really points towards ICF

I can’t work out who makes the prices up,

Like this.

i would put the membrane directly on top of the sarking boards and then your counter batten but it works both ways, many ways to skin a cat i just like the look of the membrane on top of the sarking with lapped and taped joins i had the siga rep down this week and we were talking about this very thing.

Two whys. Why do you think 9mm boards will be impermeable, they won’t why do you want an impermeable layer above your rafters. The only thing I can think of would be if you are having spray foam insulation so need a solid surface to spray against if not then on top of the rafters should be your vapour permeable layer, then your counter batten then battens.

Not really pros or cons is this your place ? how long you going to live there ? downstairs on a solid floor ? Why would you want a tray form it all in the screed and tile it level with the rest of the floor it will look 10 times more classy than a tray. Up stairs over a timber floor ? Depends if your brave enough to tank it all out and have a former, a lot more skill involved in making this leak proof. If in doubt put a tray in.

What sort of price have you been given for the trespa, I thought the bloke was joking when he told me.

Yep get it all gone, right now.

Who makes up these ridiculous rules.

Just from a curiosity point, can you tell me why you need one.

Hi will, in the grand scheme of things, an internal vapour control layer should cost about £3 per m could be money well spent.

I picked a system that I believe suited my build what is your outside finish going to be ? if it’s render then this may be ok, but if you are having any type of cladding how will you fix to this system? if you look at the pics in the brochure 99% of them are rendered.

I had the SIGA rep at my place today doing a demo on all the sealing tapes and membranes they sell you should be providing a weather proof tape to the outside and an air tight tape to the inside. Squirty foam just doesn’t cut it anymore and will make your triple glazed windows a complete waste of money if not sealed properly.

They look nice @DonGillies who’s windows are they. All i I would add is make sure you look at how you are going to air seal the frames, the days of sticking a bit of mastic in are long gone. Also so look at using a nice trim to finish the render against the frame, don’t just render up to the frame and smear a bit of mastic over it, well not unless you want it looking a bit moody.

Lovely bit of timber there.

I do like it when I ask a sensible question that others are interested in. I thought the electric mat on top of ufh pipes was going to get me a good flogging.

16 degrees, good god you northern lot are tough @Ed Davies

As stones said , we stick built our last place and saved a fortune, but that’s because we built it. I would think the time you paid two good chippies, and hired a telehandler there won’t be a lot of savings to be had the spec of your frame is fairly basic, have a look for a few more timber frame companies, and maybe avoid the ones that are at the home shows, then improve the frame with a better spec insulation

Can anybody see any benefit in having electric ufh in the en-suite bathrooms (3) and bedrooms on wet ufh, that way if you want the main heating off in the warmer weather, but like a warm floor when you get out of the shower ?????.

What on earth does that mean. HYSTERESIS

Before I start to look at this loopcad thing, can you point me in sort of the right direction so a loop doesn’t want to be more than 100m i can have more than 1 loop in a zone i was planning on having 3 zones, 1, main living,dining,kitchen 2, bedrooms 3, bootroom. Any pointers

That could be them, I had a good look and they answer a lot of points that durisol miss. @Tom's Barn they have a stand at the Swindon self build centre, I haven’t seen them before lots of extras on offer over the competitors.

I think the drama starts when you have a manifold in a cupboard and you have multiple pipes coming in through the door way.

Never tried welsh before.

Yes, he’s on my to do list, saving up for all the pies.
