Best Insulation for Dog House

Like humans, dogs too need protection from the harsh weather outside. A typical dog house protects against wind and rain but doesn’t have proper insulation against cold and heat. If you are looking at making your dog house more comfortable, adding insulation is a good idea. The best insulation for your dog house is closed cell spray foam. The reason why closed cell spray foam is the right choice is that it has high thermal resistance, water resistance, and pest resistance.

Now, let’s have a more in-depth discussion on spray foam insulation so that you understand why it’s the best for dog houses.

What is Spray Foam Insulation made of?

Spray foam is a chemical component made from mixing isocyanate and polyol resin. The two react with each other and increase in volume to about 100 times when sprayed on surfaces. The two chemicals are placed in different tins and are mixed on the site by a professional.

How to Install Spray Foam Insulation

The process of installing spray foam insulation is quick and straightforward. You need to have a spray gun, hose, spray foam, and protective wear. First, you want to prepare the surface to spray, making sure to seal the windows, doors, and wall sockets.

Then, connect the gun to the hose and mix the chemicals. Spray onto the intended surfaces. Once you get your desired thickness, give it time to cure. Finally, scrub off the excess foam on the surface to give it a smooth look. Finally, clean the area to remove all the residues.

How to Install Spray Foam into a Dog House

Now that we know the general process of installing spray foam, you’re probably wondering how to go about it for your dog house. Here is a guide.

Basically, you follow the above general installation steps of spray foam even for a dog house. But, what components of the dog house should you insulate? You want to make sure your dog is comfortable in its outdoor house at all times. It’s also worth noting that most plastic dog houses come with insulation, although you can still reinforce it. Therefore, in this case, we’ll mainly consider a wooden dog house.

It would be best to insulate the walls, floors, and ceilings of a dog house with closed cell spray foam. You can spray the insulation on the interior and exterior surfaces of each component. Since dogs are curious, make sure to cover the insulation with another material. Besides, with time, insulation may deteriorate and crumble down. You don’t want your dog to eat the chemicals because they are dangerous.

Other than installing new dog houses, you can also use spray foam to repair an old dog house. Closed cell foam is ideal for sealing holes and gaps on surfaces because it fills in all cavities. Holes and gaps can allow wind,rain, or pests into the dog house.

You can also use closed cell foam to repair holes or cracks on plastic dog houses. Make sure to cover the foam with plastic sheets so that your dog doesn’t come into contact with the chemicals.

Why is Closed Cell Insulation the Best for a Dog House?

There are many types of insulation, such as fiberglass, mineral wool, and cellulose. So, why should you use closed cell spray foam for your dog house? Well, here are 3 solid reasons.

Thermal resistance

R-value is used to measure thermal resistance in insulation products. Different methods of insulation have different R-values. The higher the R-value of a product, the better insulation it forms. Closed cell spray foam has an R-value of 4.9 – 7.1 per inch. On the other hand, open cell foam has an R-value of 3.5 – 3.6 per inch.

To enhance the thermal resistance benefit of spray foam insulation is its air sealing abilities. Closed cell foam fills gaps, cracks, and cavities on surfaces drying quickly to form a long lasting air barrier. Insulation, such as fiberglass, has low air sealing properties no matter how you install it. Fiberglass can let in air and moisture, which can lead to mold in your dog house.  

Water resistance

Other than thermal regulation, closed cell spray foam is also water resistant. Holes and cracks on the dog house walls, floors, and ceiling can allow moisture and water into the structure. Water, especially on a wooden kennel, can make the wood rot. Besides, water can aggravate mold growth in your pet’s house. We all know how mold can affect the health of your dog.

Closed cell foam is water impermeable. Once the foam dries on targeted surfaces, it does not absorb or transport water through diffusion. Open cell foam isn’t the best for water resistance because it absorbs water and moisture, making it wet and soggy.

Pest Resistance

Wooden kennels are targeted by pests such as ants, rodents, and other small bugs. Pests such as rodents are attracted to the kennel by the dog food.  Pests get into a dog house through tiny holes on the floor, walls, or roofing. Closed cell foam is your best shot at forming a permanent barrier against pests. The foam settles in the gaps, and when it hardens, it prevents entry of pests into the kennel.

If you compare spray foam pest resistance with other types of insulation, spray foam is hands down the best. Mineral wool, for example, is a type of insulation made from organic materials that can allow pests such as ants to pass through. Rodents can also eat away the materials, thus gaining entry into the dog house.

Final Thoughts

Are you thinking of building an outdoor house for your dog or repairing your existing dog house? Closed cell spray foam insulation is the best for the floors, ceilings, and walls of the kennel. Insulation for a dog house is essential because it protects your pet from extreme weather conditions, pests, and moisture.
