Cavity wall insulation with 40mm cavity Information, help, tips and advice on cavity walls, ceilings and lofts etc....

[rikkik]

Hiya, anyone know of a solution to install cavity wall insulation when the cavity is only 40mm deep? The companies I've tried which have used polystyrene balls have all said its 50mm minimum and they wont do it as there will be cold spots (and trouble down the line). But surely it must be possible with smaller balls? Any ideas much appreciated.

Hi rikkik,
Suggest you make enquiries about blown fibre CWI and see if the same restriction ]s apply

thanks S. will look into that.

Has anyone attempted DIY cavity wall insulation? Or is that crazy talk?
