How To Insulate A Plastic Dog House


We’ve already written about ways to warm up a dog house, and ways to cool down a dog house.

But, this guide is specifically about how to insulate a plastic dog house.

Knowing how to insulate a plastic dog house can be a little trickier than a wooden one.

The problem with plastic dog houses is that plastic as a material is not nearly as easy to add insulation to as it is with wood.

In this guide we give a few ideas as to how you might go about doing that, and also look at plastic dog houses on the market that utilise foam in case a new dog house is of interest to you over retrofitting an existing one.

Let’s take a look!

How To Insulate A Plastic Dog House


As mentioned in the intro, you can either try to retrofit an existing plastic dog house that you own with new insulation, or buy a new plastic insulated dog house.


1. Buying A New Plastic Insulated Dog House

The easier option over modifying your existing dog house is buying a new one.

Taking a look at the dog houses on the market that are plastic and adequately insulated, there is one brand that stands out – ASL Solutions.

They offer two dog houses –  the DP Hunter Dog House (on Amazon) which is for small breeds, and the Dog Palace Insulated Dog House (on Amazon) for medium to larger breeds.

Both dog houses are made of strong plastic constructed from LLDPE resin that is UV-8 protected, and have 4 inches of real recycled foam(Styro/EPS) insulation in each panel.

This company incorporates insulation in sheets in the manufacture process, or they blow it in with a blowing machine, and then plug the holes up.

There are flat black plugs inside the Dog Palace walls – so this makes sense.

Blow-in insulation improves the thermal performance of the dog house without the expense and mess of removing and replacing floor, wall and roof linings.

You can read more about why the ASL Solutions dog houses are perhaps the best insulated dog houses for winter and cold weather in this guide.

2. How To Insulate An Existing Plastic Dog House

To insulate an existing plastic dog house, there’s might be two options:


1. Puncture the walls, floor and roof, and attempt to blow in insulation

This is not ideal because not only will you void any warranty you have for the dog house, but it would presumably be too difficult to do, and to plug the holes back up.


2. Insulate the dog house from the outside

We wrote this guide about how to insulate and warm a dog house for winter.


Things we mention you might try in that guide are:

– Patch and Caulk Up Any Holes, Gaps and Damage


– Raise The Floor Off The Ground


– Insulate the floor, walls and roof/ceiling of the dog house

You could try to line the inside of the dog house with foam, and tape over it with silver soft, flexible A/C tape.


– Insulate and line the floor

With straw and a thermal blanket


– Install a dog door
