In part to my Previous Quary concerning Condensation Build Up.. The original Frame Work of this House of course being prior to our having Purchased said Home was early 70's before the idea of Bathroom or Kitchen Exhaust Fans.. We are looking at Installing Exhaust Fans @ Both locations starting with the Kitchen.. There is presently a Box Type approx. 2 ft sq louvred Roof Vent located on the Peek of the Roof.. My Question seeing as the location of access from both Bathroom & Kitchen is in line.. Would it be Ok to Run Insulated Exhaust Hose / Piping up into the Roof Vent to be Expelled? Advice Appreciated.. Cheers Thanks
