I am installing internal wall insulation into a 1900 solid stone wall cottage. My Building warrent states the following.
New 25mm thick cavity between the natural stone wall and new insulation to be formed using 25x47mm timber battens at 600mm centres. 100mm Kingspan Kooltherm K12 to be mechanically fixed to new timber battens. 1 Layer of Glidevale VC Foil Ultra (combined vapour and air barrier) fixed to wall, with all reveals/laps taped up in accordance with the manufacturer’s printed instructions.
20mm service void to be formed between new insulation and plasterboard finish for new services – no services to penetrate the new insulation. 12.5mm plasterboard
As old walls are very uneven I would like to do the following.
100x45 C16 fixed at floor and ceiling joist, 25mm air gap behind this to the uneven stone.
100mm Kingspan tight fit between new timbers at 600 centres.
VCL
24x45 Batten – To create service area
12.5mm Plasterboard.
Can anyone see an issue with this?
Cheers
