Buying Guide

Alright so before making any purchase in this matter, you need to keep some things in mind. There are a few boxes that you need to tick so that your best garage door insulation kit purchase is worth it. Here are a few pointers:


First things first, the R-value. It is simply a value that indicates the efficiency and rate of heat loss of your garage door insulation kit. So taking it into account before getting the best garage door insulation kit is super important.

Many manufacturers keep this value/rating into consideration when it comes to the best garage door insulation kit.

This rating will give you an idea of the ‘effectiveness’ of your insulation so that you don’t go on and invest in some ineffective insulation. No matter what material you’re using, the R-value will be crucial for consideration.

Thus we recommend you try to get your hands on a material with a high R-value that fits in your garage. Typically this value ranges from 0 to a max of 16.

Remember: The greater the R-value of your garage door insulation kit, the better the insulation of your garage.


Okay so we all know that garage doors are not that lightweight anyway so when it comes to installing the best garage door insulation kit, you have to avoid adding on that excess weight.

Therefore we recommend you to pick an insulation type that does not add too much extra weight to your garage door panels. This is important because any extra weight over your garage door will affect its operation and working.

Whether it’s an automatic door or a manual one, adding insulation or extra layers of insulation to be precise will have effects on the door itself. So make sure it doesn’t become too heavy for it to work.

Perhaps radiant barriers, fiberglass, and foam are good options for lightweight garage door insulation kits. On the other hand, Cellulose varieties tend to become too heavy for garage doors in general.

Ease of installation

Like every other type of installation, the best garage door insulation kits should also be easy to install. And for most types of insulation here, it is pretty easy to get your way around it.

Here some garage door insulation kits use adhesives to stick directly onto the door’s surface while others need proper fastening. But all of these are done to ensure that the insulation doesn’t budge at all.

Probably the easiest type of insulation is the spray one. In this, all you have to do is spray your insulation on a sheet of foam.

However, spray type insulation should only be done if you have proper know-how of the process because the chance of overdoing it is high in this case. Additionally, the spray needs to be evenly used over the entire surface.

Otherwise, the best garage door installation kits can also be directly fastened onto the garage door or be fixed by pins or clips.

Type of Adhesive

Just as there are different kinds of garage door insulation kits, there are different ways to adhere your insulation onto your garage door.

This is important to consider because these different types of adhesives can either make it easy for you to install your insulation kits or make it a big hassle.

Now, there are different types of adhesives available so you have to choose the one that suits your garage door the most. Some of these include simple clips while others can be tapes or glue that sticks directly onto the door panels.

Either way, they’re fit for all garage doors. But you also have to make sure that your adhesive is also easy to remove in case you want to change them.
