House is
1930s brick-brick
In Scotland so roof is a slightly different set up.
Tiles>batten (maybe counter)>sarking>rafters If there is a felt layer it would be between battens and sarking.
Looking for some advice as looking to insulate coombed ceilings and potentially the ceiling between first and attic
Happy to be linked to a previous thread and even happier if the answer is linked to a website/publication I can read up on myself.
Our house, when moved in, didn't have any insulation at attic level. It has stairs and floored (T&G, nailed etc) and it was decided at the time easiest and quickest would be to infill the rafters with celotex. So 100mm insulation and 50mm air gap.
I've since learnt this may not have been best as the roof isn't ventilated. Sofits are lathe and render and no ventilated tiles.
Is this a potential issue?
We are now looking to do works on the first floor including atleast insulation for coombed ceilings. Proposal was lathe and plaster down and continue with celotex, with PB or insulated PB. But now concerned that this isn't a good idea due to lack of ventilation of the 50mm air gap.
We would also like to insulate between the first and attic. But with some reading online have concerns that an attic insulated above and below isn't good either.
Anyone able to offer advice?
