The process to get the inspection notes is in place. Has anybody received them since requesting the notes via the portal?

I am glad for you. I am going through hell with my council inspector. I guess it is like a lottery! My extension just needed one more inspection but council inspector made me open plasterboards to see steals, dig foundations, remove soakaway, etc …. And yes I had pictures! Then he only works 3...

I agree. Using ecotherm calculator online or even the one at changeplan doesn't help as these tools can't cope with my situation. I am planning to call ecotherm technical team tomorrow, maybe they will have an option for me and do calculations with internal insulation addition for my case. I am...

Yep, I know now .... as I said a nightmare. What would be best way to rectify/amend? Addition of insulation inside? Foams injection? .... anything else?

"A slight internal bulge from the mortar on either leaf and its compromised" I agree. But they used standard PIT (not rebated)

That's an option. But... 1st floor and loft boarded, plastered, painted and tiles in bathroom :( I was hoping that with expanding foam (or any other product) in cavities (through drilled holes across the existing plater boards and inner aerated blocks) could have been an options.

Wall tie are there but not always keeping the PIR against the inside leaf. Poor job form bricklayers. External render has been done by a specialised company with 10 years experience in the job. That's maybe why Mr BCO comment was more about U-value rather than damp. Initially he said the...

Ground floor still had walls cavity exposed around bi-folds. Punching holes from outside is not ideal (rendering done all around) or even not possible (one side of the extension is less than 50mm from neighbor garage wall.)

Thanks for highlighting the damp transferring risk. Will it also affect the u-value calculations? Yes about the builder rectifying it but I am trying to understand 1) if it can be rectified 2) the best way to rectify it (fastest). There is a back extension, a two floor side extension and loft...

Hello experts! Average home owner here, knows little about building and insulation. Large home extension being done (Half way through). External walls with blocks inside, and outside (rendered), 100mil cavity, 90mil PIR insulation boards (Ecotherm), 10 mil air gap. u-value = 0.17 (Ecotherm...
