    I am in the process of reinstating a window that was blocked up in a new downstair toilet.

    The house was built in the 1930's and notice, having removed serveral block that the wall seems to be a standatd 4in cavity.

    Could I install cavity wall batts in the available area, or is it a bad idea to have only part of the wall insulated?
