Bricking up side door

[Wooden Plank]

Hi all, thanks in advance for the help

We've just had a side door bricked up in preparation for a new kitchen installation. I've got concerns over the insulation and wanted a second opinion before starting to dispute.

They've used thermalite blocks for the external wall, which is rendered so that appears OK to me.

Then a timber frame for the internal wall, and plasterboard. No cavity insulation. I initially asked the builder what insulation he's used, to which he replied thermalite blocks and insulation board on the inside.

I've attached a picture of the board... it looks like regular plasterboard to me!

Am I being thick? Or do I get him back to put some insulation in? Inner wall has not been skimmed so easier to do now...

Thanks

He should have used 7kn concrete blocks on the outer skin, thermalites on inside wall with cavity infill.
Get him to put 100mm rigid insulation in the stud, vapour check then plasterboard

He should have done the timber frame before the blockwork, so it could of had sheathing and a membrane on the outside of the studs, although as above blockwork is better.

There's a risk of rot to that frame with that design. Is it even treated timber?

Get it re-done properly, don't pay a penny until it is.
