I can contribute my experience with storing 78s, Lps and tape in an unheated attic in Minnesota, where winter temperatures often hover below 0F. Careful attention to position in shelves was important. Otherwise, those materials survived with no apparent ill effects, as evidenced by the subsequent half century of life after storage. As winter cold is dry, it seemed most important to maintain a more-or-less constant temperature. An dry unheated garage should offer satisfactory storage.
