ASHP & triple glazing

[nowty]

Those before photo's really scream why you need the top end 3G, I had not realised there was so much glass, especially on the side.

I think your going to notice a big difference, and should really compliment the recent air source heatpump.

Cheers Nowty, it's ALL glass!

My original mental allowance for this set of improvements was £40,000. It's coming in after grants at £26,000. I am in my parsinomus Scottish fashion now wanting motorised blinds, a pint of Guiness and £10,000 change.

At the outer end of the pricing spectrum we were being asked for £59,000. No grants, no change and sadly no Guiness. That last is a travesty.

Lesson in this, it IS worth diving deep on this stuff. Wait a minute, this wasn't planned. That £23,000 difference between high quotes and agreed IS a 22 Tesla Model Y RWD.

Weather looks good.

The last unknown space in the house. Haven't been in there in 28+ years. I was offshore when these windows were fitted. Will need layered up with insulation or a few bags of vermiculite thrown in. It's the space above the ceiling in daughterly's room.

Will have visual access once the sill is removed.

07.50hrs (drums fingers).






A quick check for later reference. See how much we can close that 1.4 deg gap.

Good luck with the 3G mate... You would expect it to make a lot of difference, especially with how much glazing there is.

In my urge to fill the seconds with stuff while we wait I've just went around the house and taken temperature reading on adjacent wall/upvc frames. A few inches apart max on each reading. The upvc window frames are on average 20.7% lower in temperature than the adjacent wall.

At the extreme end of what we have here which is the Vermiculite recently filled front lounge wall v's a North facing window 2g glazing bar on a average temperature day of 13 degs the difference is 17.6 degs v's 11.4 degs or 35.3% colder

If we can't improve significantly on that i'll get my coat!

They're here...

We have aluminium bi fold doors in the back. I remember doing temp readings on them last year and I'm sure the frames were a lot lower temp than the glass (double glazed).

Maybe the frames are more of an issue than the glass. Do companies insulate the inside of the frames? Maybe could be a good business model if they don't. Retrofit insulating window frames. Screw small hole in uPVC and pump it full of some type of insulation (polystyrene beads or something?)

The multiple sealed air voids with no metal reinforcement in frame are the thing apparently, along with plastic glazing bars? It is an impressive system. Way back in the thread when I was looking for and deciding which way we'd go I met a nice lassie called Shannon at Window Supply Co In Aberdeen who supply our fitters KSM glazing. She told me that these zero90 frames were developed by Liniar for an anticipated higher building reg's standard that was then rolled back as too high a bar for general estate builders to achieve (apologies to those fellas, no insult meant). The company then went ahead anyway and produced the frames and that's where I come in with the old self choice . My understanding is that the complete 3g unit can get to as low a value as Uw0.6.

I stopped looking at that point as it was as good (better) than I thought i'd get to or need bearing in mind the house design limitations. If anyone goes further i would be interested to hear what sort of Uw values are being offered in the Scandinavian outfits? Not a competition but I wouldn't mind knowing how far the tech has got to over there?

First window is out, North side too!

[Richard77]

Nice day for it... Hopefully not too windy!

[Joeboy]

Off to the races One side of the old window was wedged in place. No brackets, no screws.. just friction and silicone

Onwards & upwards! The bottom rail gap will be foamed before they fit the window and finish foam in. Good lads, our meetings have not been in vain.

Nice to see them off to a good start

If you upload multiple pictures to Post Image it should give a gallery link, could you post that link please, wil save a lot of toing and throwing on the tablet.
