Is there anyone who does not cry out for noise-free or perfect temperatures during any season? So, insulation is undoubtedly crucial because it helps to reduce the hot temperatures in summer and cold temperatures in winter and creates a noise-free environment in factories and your houses.
Besides this comfort, there can be some danger you will find when you are using insulation, especially for firefighters. Why?
Because it can be laborious to control a reeking fire in different types of insulation as the updated version of the technology is not well-grounded yet to look into the fire.
So, in this article, we will talk about the flammability of insulating materials.
Hang tight!
Is Insulation Flammable?
Basically, I’m going to shoot the breeze about the different types of insulation. Perhaps you already know how dangerous the use of insulation is. However, many traineeship firefighters and pyro people are inquisitive to learn if insulation is flammable or not?
It has no specific answer because there are different types of insulation that are made of different materials. As a result, some of the insulations are flammable, and others are not flammable. Although most insulation materials are very specifically designed, insulation can be flammable sometimes.
Choosing the right insulation material can be substantial. Always select the best quality of materials for the insulation, which will be adjustable to your climate and surroundings. So let’s check out the most common insulation. They are:
- Cellulose insulation
- Spray foam insulation
- Icynene spray foam insulation
- Fiberglass insulation
- Polyester insulation
Let’s know about the flammability of the insulation that is made of different materials. You should always select fireproof insulation as it will prevent you from burning.
Is cellulose insulation flammable?
Yes, cellulose insulation is flammable because cellulose is primarily made of paper which comes from plants. It is also known as loose-fill cellulose.
If the temperature is above 350 degrees Fahrenheit, cellulose insulation goes through thermolysis, known as pyrolysis. Most of the firefighters imply that the most flammable insulation is cellulose insulation because it disperses fire at a rate of knots and causes injury.

Is spray foam insulation flammable?
The ignition temperature of spray-type foam insulation is 700 degrees Fahrenheit. It is considered a fire hazard, although it is properly prepared with heatproof chemicals. If it is dry, it can still burn if the temperature is above 240 degrees Fahrenheit.
Spray foam type insulation is also one of the flammable insulations made of different cellulose insulation materials. This is like shaving foam, but when you apply, it becomes an impassable blockade.
Point to be noted, not all spray foam-like insulation is flammable depending on the density of the foam.
Is icynene spray foam insulation flammable?
As I said, not all spray-type foam insulation is flammable. It is considered non-flammable. Suppose you apply fire on the icynene spray foam insulation again and again. In that case, it will automatically stop burning and reduce the spreading of the flames as it is designed as a fire-retardant.
Normally, the best temperature for any kind of spray-type foam insulation is 180 degrees Fahrenheit.
What is fibreglass insulation?
Fibreglass insulation is one of the prevalent insulation materials made of reused glass and clean and unpolluted sand. It functions to reduce the heat and cold, which gives you comfortless and a sound-free environment.
Is fibreglass insulation flammable?
According to a study, fibreglass insulation is one of the least flammables among all the other kinds of insulation. It is the most used insulation material.
But it can sometimes be explosive as it is attached to papers or aluminum foil. It can also cause melting problems, although it cannot burn.
If the temperature is more than 1000 degrees Fahrenheit. This is made of glass mixed with plastic polymers, which is customarily flame retardant. You should not keep fibreglass insulation under a temperature above 212 degrees Fahrenheit.
Most of the insulation is designed as fireproof nowadays, which reduces the chance of combustion.
There are some advantages of using fibreglass insulation and also disadvantages.
Advantages:
- It reduces heat and cold at your home as well as at the office or factory.
- It reduces mold and increases energy efficiency.
Disadvantages:
- It can cause irritation in your lungs, cancer or disease and breathing problems.
- It may cause skin irritation.
Is polyester insulation flammable
As I have already given you little deets, most manufacturers are making non-flammable insulation nowadays as most of the firefighters are injured because of the accident caused by insulation, especially cellulose insulation.
Polyester insulation is also non-flammable. So if it catches fire mistakenly, it will burn inchmeal, and there is less probability of spreading fire, and water can stop the fire.

Can fibreglass insulation catch fire?
No, fibreglass insulation cannot fire as it is made of glass which is non-flammable. However, it can cause a fire if it is not under suitable conditions.
What do you use to protect fixtures in the attic when blowing insulation?
Using an attic for insulation helps you to lower hot and cold temperatures and its cost. However, sometimes blowing insulation can cause a fire, so you have to be careful when using these types of insulation.
You can use wire mesh which will provide an effectual hindrance. There is a specific wire mesh that will help you to protect fixtures in the attic when blowing insulation: Stucco has two types:
- ¼ and ½ inches mesh.
What insulation is flammable with recessed lighting?
The most explosive with recessed lighting is cellulose insulation, as it is made of paper that comes from plants. It can cause a fire if it is kept beside a blazing hot recessed tin or container.
Another insulation is rock wool insulation which is one of the safest flammable insulations among all the insulation. However, the flammability of insulation is not much of a problem if you use proper recessed lighting. Some of the best-recessed lightings are:
- IC rated recessed lighting: It works perfectly for blowing insulation which can mostly see in attics nowadays.
- IC non-rated recessed lighting: It is also suitable for insulation. You should keep 3 inches distance between the insulation and non-rated recessed lighting.
Why should you care if your insulation is flammable?
We all know that most of the manufacturers are trying to make non-flammable insulation, and they are treating it with fireproof chemicals, but it can still be considered a fire hazard.
If the temperature is very high, the burning accelerates, producing toxic and black smoke resulting in the respiratory system’s infection and skin irritation. In addition, it causes severe injuries and destruction of houses or factories.
So, you must care if your insulation is flammable and always understand the structures of walls and types of insulation you are purchasing. If you do not understand, ask the Constructor laborer or Sheet metal workers, specifically insulators.
Conclusion
I believe this article has given you a clear idea about the flammability of the different types of insulation made of different materials. Additionally, I have given a pinch of ideas about recessed lighting, and it’s a risk.
