Controlling the outside temperature while remaining comfortable inside may cost more than you imagine. Gaps by your door frame, poorly fitted doors, and other common insulation issues can cause air leaks that increase your energy costs. Thankfully, there are a few ways to protect your home and wallet from this type of situation. Read on for easy exterior door insulation tips to keep your home protected all year long.

1. Place a Door Snake

Also known as a draft stopper, this might be something you have seen but never acquired. It is one of the lowest-priced solutions as it can be found in most specialty stores. These come in pre-sized sets that can even match the decor of your home. Simply place them under the door frame and instantly insulate your door. It’s also a great temporary solution that can be removed if needed.

2. Install a Door Sweep

A door sweep is a simple metal strip that attaches to the bottom of the door frame. This is a more permanent solution, but it’s also a DIY solution. Most kits are available at specialty shops and come with easy-to-follow instructions. Follow the instructions and place door sweeps on every exterior door, particularly those that get opened often.

3. Get Some Weatherstrips

This varies from weather to weather, and you would need to choose the one according to the climate you live in. Apply the strip to a clean, dry surface. Also, be sure to check for gaps in the walls around the door. You can use caulk to fill in any gaps you find. Weatherstrips come in different styles based on the type of door frame you have:

  • V Strips: Made of aluminum. These are long-lasting and go on the top and sides of the door. This is an excellent choice for back doors and garage doors.
  • Foam Tape: It comes in different materials, thicknesses and widths. There are two types–the open-cell, which controls temperature, and the closed-cell–which controls temperatures and humidity. This option is more visible but inexpensive. It can be helpful for side doors and back doors.
  • Reinforced silicone: Offers the best insulation among all options, but it is harder to install. It is recommended that an expert do this to ensure it works properly. However, it’s almost invisible and will look nice on front doors.


It’s relatively easy to use these exterior door insulation techniques. If you have questions, discuss with a professional to find the best insulation method for your home.
