Best Garage Insulation Kit Buying Guide 

Deciding on a garage door conversion by an insulated designed model or maybe appending insulation to an already existing door is a fantastic idea. It may look like an extra cost to you when you think about adding a secondary structure on your garage by adding insulator, which protects your garage door. If you feel for the long run, it can benefit you in many ways. For example, during cold, the paints or storage cleaning things in the garage get poorly affected. Again during summers, your vehicles go through much wear and tear due to warm exposure or dirt and dust as well. Even with the weather, you need to keep in mind the different types of lubricants used in the door.

Hence deciding to invest in an insulator kit is a brilliant idea, but at times it leads to the significant confusion when it comes about the proper item which can suit your requirement. During the installation process make sure that you use the best garage door lubricant for the proper functioning of the moving parts.

Let us get an accurate idea about the different aspects of a garage door insulator before you plan on investing in any of such products.

Classification of Different Insulation

Fiber Glass   

It is one of the familiar and favorable materials used in the construction. Various minuscule glass fibers consist together to make fiberglass, and mostly it is available in roll packing or loose fillings. These look similar to cotton candy, but it may cause skin irritation. It traps the air in the pockets around every fiber and therefore maintains the heat and cold temperature firmly. When the glass door insulation is composed of these materials, then you can rely on sound redistricting ultimately.  Mainly to create panel kits, these pieces of fiber glasses are required.


These are recycled foam which balances the eco-friendly environment. Any dimension you want can be derived by cutting these solid sheets into pieces according to the length and size of your garage door. Compared to the fiberglass, these are much more rigid but it is, hard to work with. However, when it comes to durability or water resistance, it proves quite better. A proper sound barrier can be formed by using these forms, and of course, temperature regulation performance is also impressive. These are mainly found in between the steel layering of the garage doors. It can act as a backup with vinyl in case you have a single layering of steel in the door.


Insulation, which is composed of foil bubble wrap, which is again flexible, can be derived by using this material. This foil amazingly does heat-reflecting trap. Usually, you will get it in rolls. These are typically used for fillip up the gaps in between the steel door coatings. Hence they can be expanded as well. Fewer dents can be seen due to its usage. The thickness is about an inch or half, and it makes it smooth to cut the desired dimensions according to the door size. Though it helps to keep your garage fresh in summers and warm in winters, the sound restriction or street noise quality is not that great as compared to other materials.


Whenever you are planning for investing in an insulator, R-value term becomes very repetitive. The meaning of this is the resistance; which again denotes the ability of the materials which can prevent the flow of the temperature. So the increased R-value results in the best efficiency and performance of the insulation. If you have a separate garage with existing insulated walls, then you can go for R-value around 10 or maybe more. If it has no insulation already then opt for six or seven R-value to get a decent result. For attached garages, go for an insulation R-value of 11-12 or even more.

U Factor

Another term that you will often hear while researching about garage door insulation is the U factor. It denotes the heat flow via a material, so the low the number of U factor, the better the performance of the door.


Please ensure that the weight of the garage doors does not increase due to the insulation. If you add extra weight, then operating the garage doors can be difficult. Once the installation is done, you can call a professional who can check the door operation.

Insulation Compatible With Various Door Types


Any insulation can be adjusted well with the robust built of steel quality. In the frames, you can improve the adaptable fiberglass insulation or even the foiled bubble wrap easily without any hazards. In case you are inserting fiberglass, make sure that it only touches the door and not portrayed outwards. Polystyrene strips can be cut into pieces to get the desired dimension depending on the door side panel.


The sturdy polystyrene foam can adjust better with wooden structured garage doors in an uncomplicated way. You can trim down the foam boards according to your preferred sizes in between the frames of the door. To get a better built, you can even try using two layers replacing one. This can be better for lasting long and better performance.

Garage Doors With Windows

In case you have windows attached to your garage doors, it’s a brilliant idea to affix an extra layering of sealant on the edges of it. This can be done after insulation takes place. Depending on the size and location of the windows, you can go for Polystyrene foam built for your door. If you have regular windows rectangular almost at an eye-level, opt for foam boards. Also, for the metal on a metal part for the window, you can use wd-40 specialist white lithium grease spray with smart straws to keep its movement.

Flat Garage Doors

Both Polystyrene and Polyethylene are good ideas for flat doors. With the interior of the door, you can affix these by merely adding double sides duct tapes or maybe strong adhesive.

Open Garage Doors

When we think of best garage door openers, flexibility is the one thing which comes in our mind. So it is better to invest in fiberglass or Polyethylene. For creating a sound restriction, of course, you can go for fiberglass. If insulation isn’t for properly, then you may face issues while door opening and closing purpose.

Warmer climate Garage Door Insulation

Radiant shield insulation is a better option when you are trying to insulate against the heat waves. Two sheets of reflection can do this. Mylar is the typical material which is used for the inflated glossy balloons opposite to the bubble core. So you can use a piece of cardboard on the alternate side. Again keep this in mind it is not an as effective method because fire issue can come up. Moreover, quick-drying is another disadvantage in this process.

Creating an air gap in the intermediate position of the door tracks and insulation can give you better radiant barrier. You can tear a few strips of insulation to get this. Keep in mind to keep the length of these pieces long from the door till floor and should be thick by few inches. Add them to the entrance ends (you can add two if required). During primary layering, keep the air space of half an inch between the garage doors for better temperature regulation.

Cold Temperature Garage Door Insulation

During winters due to extreme coldness, the vehicles or even the other things stored inside the garage often gets affected.  Insulation is a quick process and it is worth to invest in it mainly for users who reside in the colder regions. Try choosing insulation with R-value of 6 or more for such colder areas or temperatures. For this, you can opt for fiberglass without any doubt.

Even adding any extra weather stripping on all the sides of the door can also be beneficial. For wooden garage doors, go for the nail on weather sealing. The best feature about the metal doors is they have an existing track at the lower end. So you can append caulking in the windows and cracks around the doors can be filled. In colder temperature, you can use silicone lubricants for the moving metal parts of the garage door for proper functioning.

Weatherstripping is affordable and is very easy to install. There are many hardware stores from where you can get the door seal kits as well.

Other Tips While Insulating


All the kits are not suitable for every door size. Although you can cut down small pieces suiting the correct size. There are pieces that become hard to fit. So when you are looking for garage insulation, make sure it is approximately the right height and width from the starting point. This can be a great help after installation.

If you can find gaps between the doors, then insulation is not that effective. So before you begin to check the door size, which can lower down the gaps.


Before investing in the garage insulation kit, make your budget. Remember, always the superior and high-end quality materials will incur more costs.  To get sufficient quality of insulation, the ceiling price will also be taken in to account.

Whenever you choose the garage door insulation, make sure to check how much energy consumption benefits you are receiving in an entire year. Go for doors with exceptional track quality, frames, and rolling techniques. Make sure to invest in products which results in less or no amount of air leakage.

Benefits Of Insulation

There are various benefits that you can avail while insulating your regular garage doors by using the best DIY garage insulation kits.

Energy Consumption

To reduce the utility bills, it is the best idea for insulating your garage doors. The prime function of the insulated gate is to trap the heat during the winters and restricting the hot air from getting inside the garage during summers.

Your cars, paints, sealants, etc. can be less damaged due to temperature variation after insulating the doors.

Noise Reduction

In regards to the older version of garage doors, the insulated once creates low or no noise issue.  Mainly it is observed the backdated garage doors have track mechanism. Due to this, it creates a loud, jerking sound. The garage door rollers sound can squeak very much. Worse lubricated hinges and torsion springs contribute to the music more. If you are getting more annoying sounds from your door, then opt for insulated doors.

The insulated door creates less sound because of the tight built as compared to the traditional garage doors. They are much heavier than the older ones and are mainly put in between the door layering without any air pass. Hence, no vibrating noise is created.

For different moving parts of the insulated garage doors likes hinges, tracks, etc. you can use different types of professional garage door lubricant once in every six months. Professional constructors often advise using a good garage floor coating to make sure your garage doesn’t lose warmth.

Durable Doors

The strength of the parts of your garage door also increases with the help of the insulation process.  Insulated doors are mainly composed of steel or aluminum frame. When these frames are filled with insulation, they get in between the single or double steel panellings. It forms a lightweight construction, which gives more energy efficiency.

Whereas, the older garage doors are mainly built with thin steel strips and no insulation. So car denting or damaging happens more in uninsulated garage doors.

Store Space

You can convert the messed up unused garage room into a better living area. This living area can be used for any work or relaxing purpose. Even you can modify the structure and transform it into a store or for business purpose.

Due to the climate changes the mold formation increase or maybe the paints or cleaning accessories gets damaged. For example, in winters, the battery backup of your vehicles goes down. So to avoid these property damages insulation can be a useful investment for the long run.

FAQs On Best Garage Door Insulation Kit
