How to Insulate a Dog House?

How to Insulate a Dog House

You may worry about how to insulate a dog house, especially if you keep it outside.

Giving your dog a blanket or even some hay will help keep them warm, but insulation is the best way to ensure their comfort.

Your dog will still appreciate the blankets and soft furnishings, and the insulation will help keep the warmth inside the house. 

The best method of insulation for your dog home can vary depending on the type of dog house you have.

Here are some simple steps on how to insulate a dog house. 

How to Insulate a Dog House?

Ground Control

The first tip on how to insulate a dog house is by lifting your dog’s house off the ground to improve insulation.

It will be difficult for your dog to control his body temperature and generate enough heat to warm the dog’s house if he is allowed to sleep directly on the floor. 

There are several options for lifting a dog house off the ground, and you don’t even need to go more than a few inches.

A few bricks, wood, or even an old pallet may be used to raise the dog house creatively. In any case, make sure it holds steady.

Once the doghouse has been lifted off the ground, a barrier must be built to ensure that warm air from the inside does not escape through the bottom.

Putting a sheet under the dog house’s wooden foundation is a good idea. This will prevent moisture from entering the dog’s home and help retain some of the heat inside.

Finally, you should ensure that the floor of your dog’s house is made of soft, warm materials. 

Pieces of carpet pieces, blankets, and towels may all be used. You may go on to the next phase after you’ve resolved the floor issue.

Determine Insulation Type

There are a variety of methods on how to insulate a dog house, but they all include the use of insulation. The three most common methods are traditional insulation, foam pieces, and spray foam. 

Traditional insulation installation is the most effective and long-lasting option; although a foam piece or spray foam may help temporarily, they are no replacement for traditional insulation. 

Decide how much insulation will be required by first measuring the inside of your dog house. Insulation may be purchased in sheets and then easily trimmed and formed to the desired dimensions. 

Insulation is problematic due to its irritating nature and the rashes it might cause. To avoid skin discomfort during installation, use protective clothing.

Installing Insulation

You may begin insulating the dog house’s interior walls as soon as you have your insulation materials.

The insulation may be easily fastened to the wooden dog house’s walls. The insulation may be cut into strips using scissors and then stapled to the walls. 

Construct the dog house’s ceiling as well as its walls. Don’t bother insulating the dog house floor. Put down a different floor covering.

Covering and Protecting Insulation

Once the insulation is in place, you will be nearing the end of the job. The next and maybe most crucial step on how to insulate a doghouse is to install a cover over the insulation.

When used on humans, this substance causes itching and irritation; it might have the same effect on dogs. 

You may cover the insulation with wood panels or use heavy-duty plastic and staple it in place to form a barrier.

It’s important to keep your dog away from any item you use. Do not let them get beyond this line of defense and into the insulation itself.

Checking the Condition of the Dog House

As discussed in the previous step, you should take every precaution to ensure that the insulation does not come into contact with your dog. Make sure the insulation is still in place by inspecting your dog’s house regularly. 

Whether you want to keep your dog warm, check to see if the barrier you set up is still in place and functioning properly.

This is something that can be checked regularly without taking up too much time.

Materials Used to Insulate a Dog House

Insulating a dog house may be done with many different materials. Insulation is essential if you want your dog’s house to keep as much heat as possible during winter. 

It is also essential if you just want to reduce your pet’s time on a heating pad or other supplementary heating source. Insulation for the exterior walls is possible with some, while others are better suited for usage inside. 

In addition to their usual use, some of them may be utilized as a wind-blocking flap on the door. Let’s go through some of the best and most common insulating materials.

Fiberglass Insulation

Pink fiberglass is a superior insulator, as are many other options here. It’s not too expensive and can be set up quickly. Fiberglass-insulated dog kennels are among the most comfortable available. 

Furthermore, among building materials, fiberglass has one of the greatest R values (an indicator of heat insulation, with a higher R-value indicating superior insulation).

If you don’t want to make a big mess with a saw, you may alternatively just use some heavy-duty scissors to cut it. 

In contrast, fiberglass is quite irritating to both the skin and the lungs (airborne fibers). This necessitates using protective equipment such as gloves and a face mask if handling the material. 

To further protect your dog from possible danger, you could install panels over it. Furthermore, it is vulnerable to water damage; thus, protecting it with a cover is essential.

Foil Bubble Wrap

It’s founded on a concept that’s as straightforward as it is effective. The wrap works in the same way as your blanket does.

A sheet may greatly reduce temperature gradients across its surface by trapping air between its fibers. 

To be sure, this isn’t the regular bubble wrap you buy at the store. This variant adds aluminum foil to the standard wrap. Its primary role is as an insulator. 


Insulating a dog kennel with wood isn’t the best idea. However, you may still repair the inside by cutting panels for the roof, walls, and floors.

For better insulation and longer-lasting wood, applying a water sealant is recommended. 

Using cedar timber or another softwood is recommended because of the abundance of natural air pockets found in these materials.

Wooden dog houses are preferable to those made of plastic or, even worse, mesh metal wires, and kennels made of wood are not always awful.

Spray Foam Insulation

Spray foam is the way to go if you’ve got a little more cash, and fancy finishing is a must. It may be used with little effort and grows to fit any area. Mold and dampness don’t have a chance against it, either.

Setting up the panels around the inside and filling in the gaps with spray paint is all required.

Avoid the expense of paneling by simply spraying between the inner and outside walls of your dog house. 

However, spray foam may shrink with time. Since it expands rapidly, using it properly needs planning and experience.

Reflective Coil

Many pet owners find the reflective coil the greatest option because of its reliability, low price, and easy use.

In addition to being a vapor barrier and lightweight, non-toxic, and non-combustible. A section of the reflective coil may be cut off and used as needed.

In addition, it blends well with various insulation materials. Attaching it to fiberglass allows for easy concealment behind solid walls of wood or plastic. It’s similar to how bubble wrap and this are often used together. 

When combined, the insulating qualities of both materials are maximized (and R values). Due to this, both the owner and the tenant are satisfied.

How Cold is Too Cold for an Outdoor Dog?

Insulation alone may not be enough to keep your dog warm if the temperature decreases severely.

If left outdoors in severely cold weather, your dog may suffer from hypothermia, which may be deadly.

While the specific temperature at which you should let your dog warm up varies, the following guidelines will help you make the best decision possible for your dog in cold weather.

20 Degrees Fahrenheit

When the temperature drops below 20 degrees, there is a serious risk that all dogs will suffer from hypothermia.

Even long-haired dog breeds may have trouble keeping warm if left outside in these temperatures, and small, aged, sick, or short-haired dogs are especially at risk. 

In the case that the temperature drops below 20 degrees, it is recommended that you bring your dog indoors.

32 Degrees Fahrenheit

Many dogs, particularly those with short hair or tiny bodies or those not naturally adapted to cold weather, are at risk when temperatures drop below freezing. 

Only the most well-insulated and cold-tolerant dogs should be kept outdoors when the temperature drops below freezing to prevent hypothermia and frostbite.

45 Degrees Fahrenheit

As long as it stays above 45 degrees, most dogs may spend their time outdoors without being uncomfortable. Now is the time to start paying close attention to your dog. 

Short-haired or small-bodied dogs may get rather cold at temperatures below 45 degrees, and older or arthritic dogs may have muscular stiffness.


After reading this, you should better understand how to insulate a dog house and provide some better insulation for them during the cold season. 

Most people who own dogs take great care to ensure their pets are always comfortable and warm. If you can’t bring your dog into your bedroom, at least provide them a place to sleep that’s as warm as your bed.
