Good morning all, I was wondering if some of you good folk could advise me on sealing up wall electrical sockets and any openings on the walls for electrics regarding air leakage. We have have been recommended a product called 'Aerosana Viscon' by our renewable heating engineer but have recently bought Blowerproof liquid airtight membrane on the recommendation from forum members for sealing joints between floors and wall along with walls and ceilings. It's maybe obvious that Blowerproof would also to the job for the sockets etc but has anybody used it for this job, or would you recommend a different product? @Conor, did you use Blowerproof also for this or go with a different product? Thank, Joe

Turnaround times on windows?
KillyfadNewBuild replied to DragsterDriver's topic in Windows & Glazing
It's with McMullan - O'Donnell; we have had good experiences dealing with them, great customer service and very personable. Our contractor also recommends them very highly and has worked a lot with them over the years. https://mcmullanodonnell.com/ -
Turnaround times on windows?
KillyfadNewBuild replied to DragsterDriver's topic in Windows & Glazing
We're being told 10-12 weeks turnaround times. Our windows are being measured up this week. -
Hi All, I hope you're all keeping well! I was hoping to gain some advice from you who have experience sealing up for airtightness. We are going with Siga Fentrim IS 20 around all our doors and windows and have been advised to seal the joints where the floors meet walls and the ceiling meet the walls. Our house is a concrete block built house with concrete slabs for the first floor. Many thanks, Joe

Yes, there is room for insulation and the contractor is recommending some TLA even if it's only a few inches. It seems to make sense to add some insulation.

Haha great to know we can use the house for a nuclear bunker - it was within the architect's plans for the build to have 200mm concrete slabs up stairs; our contractor who is family connected and we trust didn't flag any issues with the depth. There is 3 bedrooms, 1 with ensuite, a bathroom and a hot press up stairs. The house is well insulated, we also plan for the windows and doors all sealed up with fentrim and key areas sealed. Heat pump for heating throughout the house with UFH upstairs and down.

Hi All, I was hoping to run past you all our situation with our first floor 200mm concrete slabs. We are being recommended liquid poured TLA insulation on the floor from our builder mainly due to the slab being at some parts ever so slightly uneven, so the poured insulation will work to level out the floor before the screed goes in place. I have on my notes that the architect mentioned with the 200mm concrete slabs you don't need insulation, just lay the UFH pipes and screed over them - which I may have noted wrongly. What have you done on your upstairs, or from experience what would you recommend for depth of insulation and screed? Thanks and as always, I appreciated everyones feedback. This forum as helped me so much in the last few years from an non-subscriber to now a member.

Just to confirm the concrete provider and polisher said the minimum they would do is 75mm He would always recommend 100mm as 75mm would be more prone to cracking but he said it's doable and just a little more prep work would need to be done. Hopefully this can help others down the line in similar position.

Thanks for your reply, Jack. We were meant to have more depth to work with but that wasn't the case in the end so it's now a trade off. If I want my 150mm of Kingspan insulation, I need to drop the concrete slab over the ufh to be polished to 75mm which my contractor had already recommended against but if the supplier/polisher says 75mm is fine to work with, ultimately the decision is down to us.

Hi Aine, Welcome to the forum - Newbie here too from Co. Antrim.

Hi, I was hoping to get feedback from members who have polished concrete flooring at 75mm (or close to depth) above underfloor heating. I want to maximise my sub floor insulation thus dropping from 100mm recommended by my contractor to 75mm (I have another post getting insulation advice and was hoping here to gain advice from members who maybe have a 75mm slab or close too) I am getting ready for the conversation tomorrow morning with the potential concrete provider and our contractor and was hoping to get advice from others who have polished a 75mm slab on the their experience regarding pros and cons. Many thanks, Joe

Ground sub floor insulation advice
KillyfadNewBuild replied to KillyfadNewBuild's topic in Heat Insulation
I'll speak to the contractor, concrete supplier and polishing people in the new year and see what they collectively say about dropping some mm from the concrete so I can use it towards insulation. If not, the v-value calculator is displaying the below for 125mm - if I have selected the correct option "Solid concrete - Insulation below slab"?- 25 replies

Ground sub floor insulation advice
KillyfadNewBuild replied to KillyfadNewBuild's topic in Heat Insulation
My only other option would be to push for reducing the depth of the concrete for the polished floors. If I could drop it to 75mm, then I could achieve 150mm (or a reasonable combination) but then I might have issues with more cracking and my contractor having issues and probably lose benefits from the depth and thermal mass with the concrete floor. Would grade of board come into play, as there might be a 125mm premium/platinum combination which could be the same as standard 150mm boards?- 25 replies

Ground sub floor insulation advice
KillyfadNewBuild replied to KillyfadNewBuild's topic in Heat Insulation
The photo I posted on the other thread is maybe a few weeks old (I don't have any recent photos at the minute) and the block work has progress a bit more since that photo. There are sills already in place which some are low and only giving 225mm in total to work with - plus forgive me, I have been reading this forum for a long time but I am still green and learning when it comes to new builds. My main aim is to ensure we have a nice warm house to enjoy with the family.- 25 replies

Ground sub floor insulation advice
KillyfadNewBuild replied to KillyfadNewBuild's topic in Heat Insulation
It's trying to get that happy balance; our current house suffers so much from heat loss and we just want the new house to be done right. If 125mm should get us to the recommended figure from our architect it would help bring down our worry levels haha Is there normally a two layer insulation application, i.e. 80mm then 45mm on top or below, or 125mm single boards throughout the ground floor? Thank you for your reply, it's really appreciated.- 25 replies
