Almost scared to post these but what do you think?

So comparing them it seems the same????

Baskill started putting in the windows,the builder was using some foam taday, now worried after seeing other thread it's ok. A screengrab shows Soudall. Red can. The pdf below I think is it's details... foam.pdf

Yikes,they will install them but maybe we should do something to assist? Like wash down for dust so tape sticks? Should we paint the area with something? Blimey a bit nerve wracking.

Thank you!!!!! Right PIR it is. The architect specified 150mm (50 + 100)of Kingspan K103 so I just need to find out what is the equivalent from competitors. You say it should be 200 but that may be difficult at this stage in terms of do we have a spare 50mm?

Just wondering Our plans say this " Ground Floor Construction Provide Cemfloor liquid screed, depth to ensure a minimum of 25mm cover to underfloorheating pipes - to be confirmed with manufacturer (Laid in Strict Accordance to Manufacturers Specification) on 500 guage vapour barrier (all joints taped & sealed) laid over 150mm depth of PIR Kingspan, floorboard insulation made up in 2 layers with bottom layer 50mm depth & top layer 100mm depth on 150mm deep concrete floor slab with Radon Shield (DPM) Membrane under slab laid over 50mm sand blinding on min 300mm & maximum of 600mm depth of consolidated hardcore base.... Or a screed company offered this..... For energystore TLA insulation 160m2 @ 150mm £3480 Estimated U Value 0.18 For 160m2 of cemfloor liquid screed @ 50mm £2700 I see on this many people discussing using Kingspan, price wise is there much difference? There doesn't seem to be. Everything is so bleeding expensive.

Hello, I watched a you tube saying expanding foam in the rafters was a huge no no with mortgage companies. Our mechanical ventilation guy said we should use it to help seal and make things airtight at the ends of the rafters and joists saying it would be easier and quicker than the tescon tape which he suspects will peel. I know you have to prep the surface (wash the dust off, anything else?). Oh and here is the advice for the windows. Whatcha think?

Right ok will ensure they are right. Good to know. Cheers

Yep, thanks will do. Her area will be zoned to be hot.

She has been thanks. She is in constant atrial fibrillation so we are walking a tight rope with warfarin, bisoprolol, digoxin etc. Doing well though, quite happy, she just likes it about 23 degrees lol. I haven't the heart to turn it down.

Mea culpa. I am fretting and it likely is stupid. That said, coming from the 'I haven't a clue' perspective it is terrifying. Right back to ashp. I must get that paperwork thingy off the architect that gives the heat loss calcs you all keep mentioning. Also at work and nothing much is happening so intensive building/ you tube going on with me going ah!!!!

Sorry can't answer your question and you likely know this but yesterday someone reminded me to ensure a temp probe is in the wet room floor before screed and not stuck outside in the hall as an afterthought.

That's a great idea too! Cheers. To go off piste, in Germany, Luxembourg etc I see family having their washing machine in the bathroom. That would make so much more sense but from what I gather it's a no no here.

That's good, hadn't thought of that. We have a utility room close by, I was thinking it could cater for queued up dishwasher dishes.

Fair point, it's her husband. 🤣

A friend said she detests her sink on the island because it gets too messy. Any thoughts? We can have it at the outside wall or on the island. Also sorry for all the questions. 😳

Here's the thing, we are having a granny annexe and bluntly mum requires intense heat since she is on blood thinners. We have spent 1k on oil in this leaky rented house since the start of the year. The areas she can't reach are a normal temp but for the new build the spec of an ashp is really worrying me. Not only that it has vaulted ceilings which I guess makes it worse. Yes we have 200mm PIR cavities and triple glazing but she needs fast heat. Not it to sloooooowly warm up in a day. Yes , she is nearly 87 and won't be around forever but we plan to stay there so maybe I will face the issue myself in 20 years? We met extended family yesterday and I was told how a couple who have moved into their new house deeply regret getting an ASHP since their electric bills have been breathtaking. Yes they know the fitter was incompetent but that doesn't help. There are so few here that are trained. To even get one serviced will be fun. I was watching heat geek on you tube and there was a guy in the comments studying thermodynamics who said his course wasn't covering this stuff and it should. The poor guy who had a terrible experience with an ashp had the patience of a saint. I owned a renault zoe a couple of years ago and now am back on diesel. I just get the feeling this might end up the same way and frankly it would be too expensive a mistake. We got planning permission and the plans submitted did have an ashp included. I wonder if we could change? That said that Qube house I showed you is now up for sale and it swapped from ashp to oil I see.

I called into an engineering workshop re the balcony and whilst looking at the plans said he could build our main staircase (it has a turn in it) for 2k plus. It's tempting, it would never creak. We had one years ago and it was carpeted. Great job. I asked would it satisfy building control, he said yes. Tempted. Also I guess could put it in as soon as floor was down? Like it wouldn't mind a knock.

Conor, are you happy with it? Which one did you get?

So what did you do?

Thanks, 😊

Hmmm, a bit concerned. The mvhr guy visited and was slightly shocked at how high the ceiling was (new build, vaulted, don't ask, hindsight is fecking wonderful). He said he could put the vents into the walls as high as he could. However, if heat rises, should it not be at the highest point?

So ventilation guy said loads think ashp are sh*t , expensive to run and cost a fortune to service. He said get a wee oil burner for a fraction of cost.
