How Do You Insulate Mail Slots in the Wall?

Mail slots in the wall are a common feature in many homes. They provide a convenient place to store mail, and can also be used as a place to hang jackets or other items.

However, if the mail slots in your wall are not properly insulated, cold air will be able to enter the slot and freeze your letters and parcels inside.

There are a few ways to insulate mail slots in the wall. You can use insulation material that is specifically designed for this purpose, or you can use an existing layer of insulation in the wall.

If you choose to use insulation material, be sure to cut it to fit snugly into the mail slot. If you use an existing layer of insulation, be sure to seal all openings in the insulation with caulk or tape.
