I'm looking for advice on best method of installing some loft insulation into a Victorian period house with rooms within the pitched roof area. These are original with original lath and plaster lining. The roof itself is constructed of slates laid onto a fully wood boarded roof (ie no felt). the supporting boards attached to the outside of the rafters. the access into the roof space is very limited and getting insulation down the gaps between the rafters and the laths is going to be fun. Short of ripping down all the lath & plaster (including some fine Victorian plater mouldings) is there any suitable insulation material I could use. As there is no felt and the slate supporting boarding although close is not fully sealed, could I pour loosefill insulation down into the gaps? Any advice suggestions gratefully received.
Thanks
Thanks
