Loft insulation in old house with partially sloping/vaulted ceiling

[Doggit]

If the cellotex is well fitted down into the rafters, then there won't be too much condensation coming up, and if there is a sufficient air gap, then it should rise into the general loft area before settling. Juts keep an eye on things, as the danger is that the moisture will condense, run down the cellotex to the bottom, so yes, holes drilled in the wall just under the tiles may well be needed.

Thanks again, that’s really helpful.
