Drywalls are panels generally for the interior of houses and offices. Generally, drywalls are made of gypsum. You might know that gypsum is the commercial name of dehydrated calcium sulfate.
This special type of wall is called drywall because the wall is installed without the touch of water.
So, when it comes to installing drywall in your house, you might be confused about whether drywall burns easily or not. However, you have to know the features and qualities of drywall to know their fire resistivity. So, let’s see whether drywalls burn easily or not.
Does drywall burn easily?
Drywall doesn’t burn easily. Even they are more fire-resistant than many other conventional walls. Generally, drywalls are made of gypsum that makes them more fire-resistant. It might sound that the dry paper of the wall will burn easily, but the composition of gypsum makes it difficult to burn.

Drywalls are installed in houses and offices to make the wall fireproof. So, it’s pretty difficult to burn through the drywall. Even, if you try to burn them, you will need a very high temperature.
Moreover, drywalls have gypsum in them and gypsum has water content. So, when you will try to burn drywall, the water will evaporate and the papers of the wall will flake. But burning through the drywall will take time.
So, these walls are pretty safe since they will not catch fire easily. By chance the wall catches fire, it will take time to burn out. So, you will get enough time to take action.
Will drywall burn?
Generally, drywall will not burn in a normal environment. Drywalls are made of dehydrated calcium sulfate that is also known as gypsum. The composition of gypsum is so complex that it doesn’t burn in the normal environment.
You will need a vacuum or underground environment with air depletion to burn drywalls. The name drywall might seem to burn easily. But drywalls don’t burn so easily. Even you will need high temperatures to burn drywalls.
Moreover, it will take a comparatively longer time to burn gypsum. So, gypsum and drywall need some requirements to burn. They will need air depleted environment, high temperature, and industrial furnaces to burn.
So, it seems that drywalls will not burn normally. Drywalls are not like the conventional walls that burn whenever they are in touch with fire. But the composition of this wall makes it fire-resistant. So, the popularity of drywalls is increasing day by day.
Is drywall more fire-resistant than wood?
Yes, drywall is more fire-resistant than wood. Even drywalls provide superior fire resistance than woods and plywood. Generally, plywood and wood are easy to burn. They don’t provide much fire resistance. But drywalls are excellent fire-resistant.
Generally, drywalls consist of gypsum that is one of the most fire-resistant materials. So, gypsum makes it very difficult to catch fire. Even, you will need very high temperatures to burn gypsum.
Moreover, if the wall catches fire in the drywall, it will take at least one hour to burn. So, you will get enough time to take action if it catches fire. So, drywalls are definitely more fire-resistant than wood.
Is drywall considered non-combustible?
Drywall is not fully considered non-combustible. Generally, you can’t make drywall combustible since this wall is not burnable in the normal environment.
The manufacturing material of drywall is gypsum. So, it’s pretty hard to burn gypsum in aerated areas. Moreover, you will need high temperatures to burn gypsum that is not possible without an industrial furnace. That’s why drywall is initially considered non-combustible.
But if you put drywall in an air-depleted area and an industrial furnace with high temperatures, you can burn the drywall. So, in the industrial aspect, drywall is considered combustible.
At what temperature will drywall ignite?
Drywall or gypsum wall requires high temperatures to ignite. Generally, you will need more than 451 degrees Fahrenheit to ignite the drywall. This temperature is the combusting temperature for drywall.
You might know that drywalls are made of gypsum. So, you can’t burn gypsum in a normal environment and at a low temperature. You will need an area where air circulation is less and the temperature is high.
Generally, drywalls have gypsum inside and paper layers over gypsum. So, the papers outside the gypsum start to burn at 451 degrees Fahrenheit. So, you will need more than 451 degrees Fahrenheit.
How long does it take to burn through drywall?
Burning through drywalls is not easy. So, it takes time to start burning in drywalls. Generally, conventional walls start burning as soon as they are in touch with fire. But drywalls need time to burn.
Generally, it takes 1 hour to burn drywall if the drywall is 5/8 inch X type drywall. But if the thickness is less, it will start burning in less time. For example, if the wall is ½ inch thick, it will burn in 30 minutes.
So, it also depends on the thickness of drywall how long it will take to burn through it.
How to burn drywall?
Burning drywall is not that easy. You can’t just burn drywall in the normal environment. Because drywalls are super fire-resistant. So, you have to go through a process to burn drywalls. However, let’s see how you can burn drywall.
Burning in an industrial furnace:
You might know that drywalls don’t burn in normal conditions. You will need a place where the air is depleted. So, burning it in the industrial furnace is easier.
You have put the chunks of drywall in the furnace and raise the temperature to more than 451 degrees Fahrenheit. Then the drywall will start to burn and take some hours to fully burn through.
Burning in the underground:
It might not be possible without training. But trained persons can burn drywall underground. Underground is a suitable place because of the lack of air and oxygen. Then in high temperatures, drywalls can be burnt.
Burning with precautions:
You might not arrange an air-depleted area. So, if you want to burn drywalls in a normal environment, you have to put high temperatures. The temperature must be raised over 451 degrees Fahrenheit.
But remember to take enough precaution because if you inhale the smoke of burning drywalls, it can cause health problems. You will also need a couple of hours to burn drywalls since they take time to burn.
Is all drywall fireproof?
Most drywalls are fireproof. Even all drywalls are fireproof to some extent. Generally, drywalls made of gypsum are not easy to burn. They provide superior protection from catching fire.
But type-C and type-X drywalls are not completely fireproof. They will resist fire for some time. For example, some X-type drywalls will catch fire after 30 minutes to one hour. C-type drywalls will also catch fire after some time.
So, all drywalls are not fireproof completely. Some drywalls will catch fire after desired time. But most drywalls are fire-resistant and require high temperatures to burn.
Is it safe to burn drywall? Is burning drywall toxic?
No, it is not safe to burn drywall. Burning drywalls requires an industrial furnace or protected area. You can’t just burn drywalls in a random environment.
Burning drywall can be excessively toxic. Generally, when you burn drywalls, the water will evaporate and the drywalls will flake. So, if you inhale this smoke, you can face throat and airway irritation.
Moreover, it can cause many other health issues. Even the smoke produced from drywalls can cause breathing problems. So, you should not burn drywalls in a normal environment.
However, burning drywall is not safe since it produces toxic smoke from the burnings.
Will Sheetrock drywall burn in a fire pit?
You might know the composition of the drywall makes it difficult to burn drywalls. Moreover, drywalls have paper layers in the outside part and gypsum inside the papers.
So, when you will burn drywall in a fire pit, the paper will burn first and the water in the gypsum will evaporate.
But the gypsum inside is pretty impossible to burn in the normal temperature and environment. Moreover, the smoke coming out from the gypsum and drywall is highly toxic. So, when you will try to burn drywall in a fire pit, it can harm.
So, you can’t burn the drywall in a fire pit well. So, it will be wise if you give away the old drywall to recyclers.
Final Thoughts:
Drywalls contain gypsum that is pretty difficult to burn. So, drywalls are fire-resistant than many other walls. So, when you try to burn drywalls, you will have to fulfill many requirements. Moreover, burning it in a normal environment is not safe. So, drywalls don’t burn easily.
