10 Best Garage Door Insulation Kits

Cold in winter, hoarfrost inside garage doors and much more – these problems were exactly what garage owners faced in winter. Perhaps your garage is even getting too hot – it all depends on the climate in which you live.

In fact, any extreme temperature problem can be solved with thermal insulation. Even the fact that your garage is too damp or evaporates too much can lead to mold – even this problem is solvable.

You may think that insulating an already finished garage door is a waste of money, but it is a fantastic idea. Imagine if you use insulation to extend the life of your garage and reduce the need for cleaning or maintenance.

Such a solution can be confusing to you because you have never studied the issue before. We understand that, and to make it easier for you to find and buy a thermal insulation kit, we decided to tell you about the best models and their features.

What is the first thing you should pay attention to?

Your budget and manufacturing materials.

The cost of materials varies depending on different indicators – its manufacturer, quality, thickness, and even type. There are glass fiber, polystyrene, polyethylene and other materials – all of them have different costs.

You need to determine what budget you are willing to allocate for insulation and choose the materials depending on the amount. It is also worth knowing the pros and cons of each material – so you definitely will not waste money.

The size of the garage door.

Each set for insulating the door has its own amount of materials and tools. For example, if you decide to save money and order a small set, the materials may be too little for your door.

In this case, the insulation will give almost nothing – as there will be gaps, and you have to buy new materials. If you order too much, you risk getting too much material left over. We recommend that you carefully measure the door before buying it.

The thickness of the insulation.

When measuring, you should pay attention not only to the height and to a width of the door, but also the thickness of the material it is made of. Each material has its own thermal insulation value – you only need to reinforce it with materials.

Once you have decided how hard you want to insulate the door, you will understand the thickness of the thermal insulation you need. This is also important when you choose a material!

Type of insulation.

You can insulate the room from anything – from excessive heat and moisture, from cold or altogether. You should not think that any insulation material is universal.

Their development always takes into account temperature features, so if you buy insulation against excessive heat, in the cold season you may get an unpleasant surprise.

We recommend that you check the type of insulation that you need in advance. If you cannot make up your mind – it is best to look at universal options.

You can install them both for protection against extreme cold and extreme heat. Increased durability extends the life of the insulation material.

With double-sided tape, it is convenient and easy to work – easier than with panels. One set includes four rolls, which are enough for insulating medium size doors. For very large doors, you may need a little more material.

US Energy Products NASA TECH Garage Door Insulation Kit has a low price and therefore will not make your work too expensive. Of course, installing this material can take a little longer than just working with panels.

Once installed, you will need to allow some time for the material to dry. It is advisable not to touch the insulation tape for 24 hours – this way it will fit firmly to the door and will not let excess temperature inside the garage.

4) Reflectix BP24050


In addition to the garage doors, there may also be windows in the garage that also need insulation. The materials and panels are quite large, from which it is not advisable to cut out too small details for windows.

Reflectix BP24050 is a set of insulation linings that can insulate doors, windows and will keep the hot sun and cold wind away. With the scissors from the pads, you can cut out any part of any size you need.

In order to fix the Reflectix BP24050 to the surface, you will need glue. You just apply a small amount to the surface and attach the insulation material tightly – this way it will hold.

Another property of this material is its ability to reflect light. Because the surfaces inside the room will be shiny, it will reflect both natural and artificial light.

In this way, you can not only avoid the cold inside the garage but also make it lighter. The easy use of the Reflectix BP24050 is also an advantage.

5) SmartSHIELD

Installation is as easy as with other insulating tapes. You can simply use glue and scissors to fix the right size of the plate to the door. By the way, the glue gun is much more convenient to use than glue tubes.

Thanks to the even surface, you can clean the material from the slightest dirt. Thin foam combined with aluminum foil reflects up to 97% of the temperature – no matter whether it is cold or warm. Just like the previous model, SmartSHIELD reflects any light in the room – it may be a plus for you.

6) Reach Barrier 3009

Reach Barrier 3009 is a set of plates that are great for both windows and doors. These plates do not require any subsequent maintenance and are completely safe for people.

Inside the panels, there are two layers of barrier bubble. Outside there is a reflective layer, which reflects heat, cold and light. Mounting is done as standard – with acrylic adhesive.

Clean and tidy appearance is one of the main advantages of this kit. Some people think it’s not the right material, but they are very wrong – polystyrene foam just as well as insulates doors and windows in garages.

The inside of the garage will be cladded with white material. Before installation, clean your garage panels and doors with acetone or degreaser. The kit itself is quite light and will not weigh down your door in any way.

Most of the doors in the garages are naked and have no protection from external conditions and cold. Inside the garage, you can feel a slight cold, which does not give you the opportunity to easily go into the garage in winter with home clothes.

You may have been looking for insulation kits in construction stores for a long time, but it is much easier to buy them online with delivery.

Even if you have no idea how to install them, the internet will definitely help you with this. Also after reading the article, you may have some questions, and we will be happy to answer the most popular of them.

FAQ for garage door insulation kit buyers

1. Do you really need insulation for your garage door?

Normal doors and gates are not insulated at all. Behind such doors, the temperature is highly dependent on the weather and the temperature outside. Inside them, the temperature is about 28-30 degrees and when insulated, it rises to 45 degrees.

2. What are the advantages of insulated garage doors?

Sure, no one is forcing or obliging you to isolate the garage door. Still, if you take up this issue, you can even save energy! If your garage is heated, it will be much easier to keep heat indoors and not leave it outside.

You will also be able to muffle all the sounds of actions occurring in the garage. This is especially useful if you are doing a loud repair or playing musical instruments.

3. What is R-value?

R-value is an indicator that indicates the heat resistance of a material. It shows how the material can resist the environment and store heat indoors. The higher the R-value, the more heat resistant the material is.

For a more accurate measurement you need to take the insulation value of the material itself and multiply it by the thickness – this way you will know how much heat-resistant your door is now.

For garage walls, the R-value should be 15 or more, and if you are reinforcing ceilings, increase the number by 35-40.

4. Is it necessary to additionally isolate the walls near the garage door and garage door?

Depending on the size of the garage door, you will need different materials and different approaches. If the door is too large, you may also need to insulate the adjacent walls – at least the one on which the door is located.

This is necessary to ensure that you really do not release heat and eliminate all possible remaining gaps and cracks. However, if you want to insulate all the walls of the garage, it is not necessary at all.
