Let’s start!.

Things To Know Before Installing Garage Door Insulation Kit

The garage door Insulation kit comes in a different shape, size, installation procedure, weight, and material.

So this becomes very important for selecting the best garage door insulation kit.

1. Non-Toxic

Do you know in some of the cases manufacturers uses toxic to make better insulation kits? No one can deny that chemicals are used to make insulations but these all chemicals should be non-toxic.

So make sure to be attentive to the details while selecting the insulation kit.

2. Material

The material of the garage door insulation kit depends on your budget and need. I mean if your budget is lower than the recommended amount then you can go with the spray foam.

Because spray foam is a sustainable and quick-fix solution that comes in the lower price range. 

But if your need is better than your budget. Then you should check the other materials such as fiberglass, cellulose, batts, and so on.

These are some of the commonly used insulating materials that we use.

3. Fire Resistant

If accidentally your house caught fire then what should you do? Try to extinguish the fire. This is the common thing we do.

But if you use fire-resistant insulation in your garage or house then I don’t think fire damage the house.

A fire-resistant insulation kit will protect your house and garage from fire and protect you from outer things.

4. Size

As you know, garage doors come in a different shape and size. So while selecting the insulation kit for it.

Then you should keep the size in your mind. So that you can purchase the actual and perfect insulation kit for your garage door.

Commonly we use 7 feet of garage doors, I have also the same size that why I also purchase the garage insulation kit according to my garage door.

5. Weight

If you have decided to cover your garage door with a thicker layer of insulating material. then you should select the lighter insulation material that makes your garage door lightweight.

Because if your garage door becomes heavier then you will have some other issues.

So these are some of the major prospects that you have to keep in your mind while shopping for the best insulation kit for your garage.

But Hold on!!.

I have also 2 parameters that will help you judge every soundproofing and insulation material. If you want to know then I have given below. Check out!

What Is NRC & R-Value

NRC (Noise Reduction Coefficient) Stands for noise control as usual. NRC is based on how the material is good to absorb the noise. Mainly this depends on the structure of the martial.

But if you find +0.5 NRC in the garage door insulation material. Then this material is good to use.

R-Value (Resistance Value) is a measurement to check how the material is good to stop the heat outside your house. This is a simple formula to compare 2 different insulating materials.

So if you find R-21+ per inch in the insulating material then you can use it.

So the major parameters are finished to check the best insulation kit for your garage. Now, you need to check which type of insulation kit material you should use in your garage.

Types of Garage Door Insulation

If you are living in a very hot climate then which insulating should you use? How does insulation material play a very important role to make better garage door insulation?

If you want to know about these questions then you should check below because I have given 4 important and the major insulation materials.

1. Cellulose Insulation

Cellulose insulation becomes environmentally friendly because it is made from recycled paper and other things.

This will directly plant onto the surface or in the cavity that reduces the free noise and maintains the thermal insulation inside the house. 

But if you want to use cellulose insulation on the garage door then you need to use a heavier layer. In my opinion, this will work well in the hot climate.

2. Fiberglass Insulation

Fiberglass insulation is the commonly used material that is used to make the garage door insulate and soundproof as well.

Many people, even me, also use fiberglass insulation because this comes in a pre-cut and roll size. So that this can easily be used at the garage door. 

If you decide to use fiberglass insulation then I recommend to after installing it cover it from the aluminum foil.

That works as a lightweight barrier and protects your garage from noise and thermal leakage. This is also a very convenient option too that comes on a low budget.

3. Spray Foam Insulation

Spray foam an ideal insulation material for garage door insulation. That applied from the spray gun and comes in 2 different chemical products.

The first one is isocyanate and the second one is polyol resin. Moreover, spray foam can expand 20 to 30 times from its original size that produces a high and better insulation layer.

If your budget is low then you can use spray foam on your garage door.

4. Aluminum Foil Insulation

Aluminum foil insulation is not ideal for all types of but you can use this to make your garage door a better insulator.

Using aluminum foil insulation is very simple. Just you need some pieces of cardboard, polyurethane bubbles, and aluminum sheets. 

Stick cardboard and polyurethane bubbles at your garage door surface and then cover them with aluminum foil.

This is to maintain the temperature inside the garage and prevent every spike. Aluminum foil can reflect from 95 to 97% of heat radiant so if you are living in a very hot climate then this is the right choice for you.

So these are some of the forms of insulation that you can use on your garage surface. But do you specifically want a better solution?

1. Cleaning The Garage Door

My motive is to give this step at the beginning is to make all the things better. Because when you clean the dirt, dust on the surface then all the steps become easy.

So if you want to make things easy and effective then you need to properly clean your garage door.

2. Measure The Insulation Sheets and Garage Door

After the cleaning process, this is your second step where you need to measure the whole garage door and the insulation sheet. Because every garage door is not the same.

I mean some garage doors are for single vehicles, some made for double vehicles, and some various vehicles. 

That’s why if you want proper insulation then complete this step in a proper way and note down all of the measurements. For this, you can use the measurement tape.

3. Cutting The Insulation Sheet

According to the measurements you need to cut the proper piece. Whether you are using panels or sheets you need to start from the top and complete to the down.

I have seen some insulation panels come in a pre-cut shape. So if you don’t have the knowledge of proper cutting. Then you can go with them.

4. Fixing The Insulation Kit Onto The Surface of Garage Door

After preparing now you need to fit all the insulation sheets or panels onto the surface of your garage door.

First, you need to use the double-sided adhesive tape and remove the outer surface then stick it onto the surface. 

Then remove the next outer surface and take the sheet stick onto the adhesive tape. Although you can also use adhesive glue

if you don’t want to use adhesive tape. Repeat the process until the whole garage door is covered with foil.
