[Talkingheads]

Hi all, could anyone help me out with this?
I am having new sash windows being made at the moment for a renovation project in Kent but the joiner is not installing the windows, I am with a little help.
However, I am not 100% certain about the method of fixing a sash window and what matewrials I will need to tie this in securely.
Any help would be greatly appreciated,

Thanks
