How Do You Insulate Mail Slots?

Mail slots are a common feature in homes and businesses. They’re typically located near the front door, so people can drop off or pick up mail without having to go through the main hallway.

Insulating mail slots is a common way to keep people warm in the winter and cool in the summer. There are a few different ways to insulate mail slots.

One popular approach is to use weatherproofing tape or foam insulation. Another option is to insert a layer of closed-cell foam between the door and the wall.

Some people also choose to install a thermal barrier between the door and the wall. This type of barrier is made from metal or plastic and is designed to keep heat out of the mail slot.

It can be installed using screws or adhesive.
