windows in unconditioned attic

an123 | Posted in General Questions on

My gable-roofed, unconditioned attic has lots of cellulose insulation and a single-pane window at either gable.  The windows are extremely old and drafty – but does that matter in an unconditioned attic?  Should I replace them?  I live in eastern Canada.

    No. As long as they don't leak, they are fine as they are.
