    Hello

    1. Has anyone used Styroloft boards? They are EPS laminated to ply. Advertised as lighter than normal 22mm flooring so sound ideal to me for the loft.

    2. I have a loft conversion with dormer. Only part of the loft was converted. The wall between the conversion and the loft is made of these terracotta blocks. Would they benefit from additional insulation, and how? Glue Jablite or Celotex to them perhaps? If I use the styroloft product I was thinking of dot and dabbing the boards onto the wall.

    Thanks

    Is this property in the UK?
    I would not have thought putting an EPS backed board into joists would be a good idea.
    All external walls would benefit from insulation if they have not had some already.
    What about just Eps/pir backed plaster board? You can dot and dab to these bricks. You need to be careful with mechanical fixings and drill slow.

    Just looked them up they are XPS not Eps. So will be fine.
    Though Rockwoll batts and chipboard will be cheaper and have better acoustic properties.
