hi, when hvac was installed (by former owners) in my 1940 mill cottage, the owner/installer cut a rough opening into the gable end for attic access. it is now covered by a piece of tin, screwed into the wood siding. i'm thinking of moving attic access inside the house but if that doesn't work, what can i do to make the access easier outside? i thought about framing the opening and adding a door of some sort, maybe a louvered door with fine and heavy screening behind it to prevent access by rodents, etc. or maybe just a solid door with a few screened (decorative) holes for ventilation. this is a very small, crawl-in-only attic. any advice? jingle
