    I have a carpeted timber staircase which sits above the (cold) communal stair in my tenement block. My intention is to remove the carpet and lay reclaimed wood on the stairs. Would it be worthwhile stuffing some sort of insulation into the 'triangular' gaps under the stairs before I do this?

    if you possibly can do it by lining the underside with insulation or insulated plasterboard. insulation on top could cause problems in the future with the stair picking up condensation and then woodworm as it will be colder.

    Loads of cold bridges at the corner of each right-angle. Could you underdraw in 25mm Pu and plasterboard?

    Not really feasible to insulate from underneath due to gas pipes and electrical ducting, as well as the general issue of it being shared. And the cost of dealing with all the curves.
  2.  
    I thought the 'triangular gaps' *were* to be accessed from underneath..(?) Having trouble with spatial awareness. Were you proposing to drill holes in treads and stuff insulation through those?

    Yes, I thought cutting holes through the treads (or risers) would be much simpler than going through the lath and plaster below.
  3.  
    We-e-ell... It would, I am sure, be better than nothing, but every tread/riser intersection will be a thermal bridge.

    OK, thanks Nick. Given my stairwell is not that much warmer than the communal one, it's probably not worth it at all!
