    I recently was discussing an issue in a semi-detached property with partial fill block walls. The blocks are parged with sand and cement. See below

    The same property is drywall with steel studs in most walls, except for a few international partition walls that use wood studs. I notice on several walls, mainly the wall to neighbours, that the steed studs are very visible with a thermal camera in cold weather. This is less apparent on other walls, even though they are far more exposed and a highly wind exposed position. Is it typical for steel studwork to show up on block built structures

    Part walls are notorious for being in house winter cooling systems due to them being draughty. Even when the cavity is not connected to the inside of the house (generally it is big time connected) the party wall blocks will be colder than external wall blocks and the metal studs will transfer this heat better, quicker and more efficiently than air

    So yes I would expect to see them in the real world.

    It sounds like the back of the plasterboard on some walls is exposed to external air movement somehow. Finding and eliminating the openings would be a good first step before putting beads in the cavities. The openings may also show up on thermal camera images, but they might be in the loft or under the floor.

    This end of terrace house has the typical Irish party wall system which is 4in solid block on the flat so there is no cavity as such, but for some reason that the wall seems colder. Maybe its more connected to the attic than the others, as djh alludes too.

    Certainly it seems like it is connected to outside and is getting outdoor air between it and the plasterboard

    Thanks for the feedback. I was trying to narrow down was it conduction from the concrete block or the cold air from the attic. Your point and feedback clarifies its probably the cold air rather than the concrete block. I am considering installing genieclips on one wall for soundproofing and I thought this might have a happy side effect of thermally decoupling the steel studs from the cold concrete but it is probably not going to help.

    Don't disagree with any of the above comments, however when using a thermal camera you are rarely at thermal steady state so it is quite easy to draw incorrect conclusions.

    e.g. if it had been warmer outside than next door for a significant period (even if it wasn't at the time you surveyed) then the party wall could show up as a cold wall.

    In the same vane I have photos of our EWI looking 'worse' than the adjacent less insulated brick wall when the external air was warming up externally in the morning (and EWI thin coat warmed much faster than the bricks).

    A second survey at a different time of day would allow you to check the conclusion and then move on to looking for air leakage.
