Types of insulation can be anything that adds an extra layer that is a poor conductor of heat.

For cold winters, the aim is to keep as much heat as possible inside the dog house, while in summer it's desirable to keep the heat out.

The easiest way is to make a plywood sandwich, which is then stuffed with insulating materials.



Materials for Insulation

Some possibilities of things to use for insulation are:

  • Foam board
  • Sprayed in foam
  • Foam peanuts
  • Batting
  • Used carpeting or carpet pad
  • Layers of newspaper or cardboard
  • Old quilts or sleeping bags
  • Rags
  • Old socks

Note that it is possible to use more than one type of insulation in your dog house. For example, you could have cardboard in the roof section, foam board in the walls, and old carpet underneath the floor.

However, please make sure that the materials you use fit your climate. A material that doesn't rot, like foam, is probably best for areas that tend to have high humidity or are often damp.



Specific Dog House Insulation Plans

As should be evident from the photo at the top of this page, you really need NO special dog house insulation plans. You can add insulation to most types of dog house plans, including free plans.

  • You will need to be able to do some arithmetic and perhaps make a sketch or add to the basic drawings to determine any extra dimensions and materials required.
  • If necessary, add insulation to the outside of any design so you do not encroach on the interior space and make it too small.
  • When adding insulation to an existing dog house, it may be easier to take the roof off first.
  • If your dog house has already been built, like Comet's dog house, and there is adequate room to the inside, you can fasten some 1x1s (25x25 mm) to your 2x2s (50x50 mm) and cover them with plywood. This will give more than an inch (25 mm) of insulation while allowing maximum space for your dog.
  • If you want thicker insulation and believe there will still be enough room for your pet, by all means attach the plywood directly to the 2x2s.




Additional Factors to Consider

  • Remember to insulate all the surfaces, including the roof and floor.
  • For best results, ensure that all cracks are sealed, just as you would with a home for humans.
  • For very cold, windy climates, you may wish to build a dog house double the width so you can put in a wind partition inside that starts from the front next to the doorway. This way, the dog can hide out behind the partition if necessary.
  • You can also make a front door flap out of heavy plastic or rubber to keep cold air out. Simply staple, screw or nail it to the inside of the front door.
  • Adequate ventilation needs to be maintained if your dog will use it when the weather warms up. If the roof is able to be raised (recommended), you can prop it slightly.
