Dot and Dabbed plasterboard

[mrmercedes84]

Hi

Had an energy survey done couple of months back.
One of the obvious findings were the majority of the house interior is plasterboard directly bonded to the cavity block wall.

Apparently this method has no thermal properties what so ever and was just the quick way of doing it when the house was built back in 2011 and gives no thermal or sound insulation.

As part of air tightness I'm doing now , I'm wondering how to proceed.

Would it be extremely expensive to strip back the walls and get rooms redone one by one over time.?

Was platerboard on block wall common back in 2011?

Thanks

Direct bonding was well "outlawed" by 2011 and AFAIK was never up to recommended specification.

Not overly expensive to do room by room (have done it in my parents home) as its usually only 2 walls per room that need it.
The difference is literally unbelievable .
Obviously full room redecoration afterwards to finish.
Have a look here, this is what I used. I recommend not to use below 50mm.

Hi

So you used insulated plasterboard is it ?
Did you have put timber first before the plasterboard.

Assuming two walls only as they were interior side of the exterior walls ?

Also why is difference unbelievable ? Thermal is it ?

No timbers, straight onto blockwork of external walls.

Yes, the thermal difference was very noticeable.
