If you locate attic and crawlspace access from an unheated area, such as a garage, you won't have to worry about this detail. However, access hatches inside the living area need sealing. Good gasket or weatherstripping on the stop will stop air from leaking past the cover. The key to getting a good seal is making sure the cover presses tightly against the gasket. A latch could work if it's placed properly. By making the cover out of heavy materials, the weight will keep the seal tight. |
