I am also using the underside of the pitch below the the roof build up to run MVHR and will have a curved ceiling which reduces the impact of the height of a vaulted ceiling.

What are the room dimensions and eaves height?

Thats fantastic news, well done. Does the construction figure include vat ?

Can I just confirm the supply outlets can be anywhere, floor, wall or ceiling. I have a vaulted ceiling and was planning to run radial pipe along the inside of the ridge and exit high up, central in room and nearly 4.5 m from the floor. Performance wise does it not make much difference if its in the corner of a room or high up on a wall?

Ours is 600mm for walls and roof, 400mm for first floor. Internal walls 400mm. OSB will be fixed to walls and roof on the inside.

Thank you, @PeterW, @Barney12, @Onoff.

Can someone point me to building regs requirement for insulation between timber joists on the first floor, Thank you.

I need about 80 sheets. Will look again at Seconds.

Its just me and my Dad so labour costs are not an issue. I have asked Rockwool for a U value for floor, walls and roof. I will cost it all up, Celotex is going to cost at least 4k + the screed cost which might be another 3k.

150mm insulation and 80mm including final timber, about 65mm screed.

The concrete slab is already in. Celotex seems in short supply at the moment and the cost has risen another 20% so was considering a suspended floor instead, it also avoids the final screed cost as well.

I was planning to fit 150mm celotex, UFH, screed then engineered flooring on top of the 100mm concrete slab but due to rising costs and supply issues wondering about an alternative approach. I have enclosed a drawing (by hand) which shows the build up. 2x75x47 cross laid, base timber @ 600mm centres, top timber @ 400mm centres. 2x70mm Rockwool flexi. Then vapour barrier, is it needed? , 22mm structural flooring, 25mm underfloor heating, 18mm Knauf Brio floating board and finally 15mm engineered flooring. Looking at the list not sure if it would be any cheaper but will cost it up. Does anyone have any costs for floor screed per sqm as a guide. Your thoughts appreciated as always,

Same experience Miele, Dyson and a Henry. Miele for the home and Henry for the garage / workshop.

Thanks, great advice. @ProDave @JSHarris @le-cerveau

Having MVHR in our new build but wondering about having an extract in the Plant room, its not on the drawing from BPC. It will house an unvented cylinder and buffer tank, etc. Any advice appreciated. Thanks.

Thanks Craig.

Thanks Janet, had Internorm visit this morning. Really love the quality its just the tilt and turn issue into the room. If you open them a little do they stay in position or prone to swinging into the room? Thanks for your advice.

All our windows are single pane except 4m sliding and 2m kitchen window. Internorm have quoted us for the 1500x1500, Rationel have a max width of 1300mm. So are all your windows tilt and turn except the one above, if so is the external profile different to the others? Which company did you use, so many horror stories about delivery and fitting. I did help fit my brothers Nordica windows last year, not easy due to size and weight but doable.

Thanks Peter. Got it now.

It was 30K for Inter and 31.3K for Rationel including the extras. Both include fitting + vat. Rationel want another 5K for cills, tape, packers, survey etc. Also with tilt and turn they are limited to 1300mm width, we have 1500mm. So top guided is an option. This is what I wanted to hear about. Do you use the tilt option much, issues with opening across the cill into the room etc. @IanR Question, If I add a quote is the member notified? @ProDave

Rained off today on Dartmoor so time for some window shopping. Internorm / Rationel have both quoted for triple glazed, tilt and turn and prices are near identical. Can any owners of the above offer any practical advice regarding opening types especially tilt and turn. Thanks all. @Stones @JanetE @Barney12@IanR @dogman @ProDave @craig

Exactly as Prodave and Peter.. I think we moved 500 tonnes +. We used a 3 tonne digger which was a bit small tbh. I set the profiles as far back as possible on the site so we could reuse them, checked again for the blockwork after the concrete pour. It was all quite enjoyable.

We set out and did the ground works ourselves, made some timber profiles, Measure the diagonals as well. We took many hours to get it right. Just took a measurement from an existing fixed point on the site to start. Extended 2m out on all sides as well. We will have more digging out todo once house nearing completion.

@Barney12 I hear you.

Good topic as our kitchen has a vaulted ceiling, 4.5m high and we will have central island with induction hob. Similar size to Alphonsox. Looking at downdraft extractors, is it best to have recirculating than external extract due to having MVHR fitted?
