Can You Burn Drywall in a Fire Pit? (Is It Toxic to Burn?)

Can You Burn Drywall in a Fire Pit? (Is It Toxic to Burn?)

Drywall has certain fire-resistant properties. It’s constructed of gypsum pressed between two pieces of thick paper. Also, Gypsum is a sensitive mineral that can’t be ignited by itself. Drywall’s fire resistance isn’t only a function of how it’s made; it’s also a function of how it’s used to create partitions and roofs.

Fire regulations and local standards will be well-known to local drywall contractors, who will be able to help you with your fire pit. There are a few intriguing insights you’ll learn in this article, such as whether you can burn drywall in your fire pit and how it burns.

Can You Put Drywall in a Fire Pit?

Burning drywall in a fire pit is not recommended, yet many individuals continue to do it nevertheless. Most drywall is manufactured using fire-resistant material that cannot burn completely. It is not suggested to use the drywall since it might cause dangerous pollutants to be released into the air.

Depending on the condition of the drywall, it can either be recycled or thrown out alongside the garbage from the building site.

Despite this, the components, such as gypsum used to manufacture drywall, are fire-resistant. Consequently, a single piece of this material does not catch fire as quickly. Because it is so thin and vulnerable to damage, the top layer burns easily; yet, gypsum requires a very high temperature before igniting it.

A fire pit is not capable of producing that high of a temperature. It is only conceivable in industrial furnaces, yet the odds of it happening are still equal.

Can Drywall Catch on Fire in a Fire Pit?

Yes, it can, but depends on the temperature. Each of the materials is susceptible to damage in a fire pit at one point or another. Tolerance and durability are inherent in everything. There is no way to avoid the deterioration of materials; everything eventually wears out. However, although certain materials are easily broken, others are very resilient.

Drywall is a more concrete substance that can be used on walls instead of plaster. This is a common practice. However, since it is put on the interior of a structure, there is a need to sometimes check on the effectiveness of the safety measures.

Drywall is made by pressing gypsum and water between sheets of paper until it becomes a paste. Although the paper itself may be burned and the combustion process will result in water absorption, gypsum can only be burned at very high temperatures.

Drywall is very heat resistant due to the presence of water in the gypsum, which evaporates and, as a result, efficiently lowers the temperature of the material around it. Therefore, despite the rapid decomposition of the paper covering, the gypsum core of the drywall will, for the most part, retain its original appearance.

Drywall is a popular material used in modern construction because it can be used to cover separators, form internal partitions, and provide firebreaks. It has great resistance to fire, is not hazardous to the paper coating found on individual sheets of drywall, and is thus difficult to burn in a fire pit. The production of drywall sparks the fire intensely.

Is Drywall Toxic To Burn?

The simple answer is yes. This is because the toxicity of drywall during burning is not negligible since drywall contains gypsum, which, when burned, releases toxic fumes, dries out and begins to flake once the water content of the gypsum is driven out during the combustion process.

Inhaling the particles produced as a byproduct may lead to various health issues. As a consequence of this, burning drywall is not advised for reasons related to safety. Drywall has a decent level of resistance to fire. It is already made out of gypsum but contains several toxic elements, that can be catalyzed by fire (During burning). It also contains two layers of gypsum that looks like sturdy paper.

What To Do With Drywall Scraps?

1. Throw Away When Required

Do some research to determine whether your local trash collection service accepts your drywall and what condition it must be in to be accepted. For instance, some areas could ask for all spent construction materials left out for bulk collection unbagged, while others would want them to be bagged like garbage.

Adding drywall to the garden will also help to aerate the soil and provide a more favorable environment for plant roots. Some farms swap agricultural gypsum with drywall-sourced gypsum.

2. Charity Donations

Non-profit organizations like Habitat own a series of warehouse-style home renovation businesses for Humanity. These stores can find everything from couches to building supplies to kitchen sinks.

In addition to new and used equipment and supplies, they can collect waste drywall for recycling purposes. Look for a local organization that accepts construction materials if you can’t find a business like this in your region.

3. Utilize Buy Nothing Groups

You can find local Buy Nothing groups on mobile applications and social media platforms like Facebook and Twitter. Anyone can give away almost anything to anyone within a few miles of a Buy Nothing organization.

A few scraps of drywall from a recent job are perfect for your local Buy Nothing organization since many home repair projects need a few tiny pieces.

What Can You Burn in a Fire Pit?

Numerous other strategies and resources may be used in this situation, with firewood being the most effective of the lot. Bricks made of wood may be burned using various types of wood, including oak, alder, pinion wood, hickory, cedar, fruitwood such as cherry or apple, mesquite, and pecan.

Before deciding which wood products to burn, it is important to consider the many qualities they bring to the table. The ideal materials are tried-and-true aged wood rather than freshly cut pieces of wood with a high moisture meter.

Wood bricks, however, are an option for everybody, provided there are enough of them. Since pinion wood is effective in warding off mosquitoes, it is a great choice for fire pits.

In addition, some types of wood, such as apple, pecan, and cherry, smell nice when burned as firewood. Oak, mesquite, and hickory all produce significant heat during the combustion process.

Can Drywall Be Used Around a Fireplace?

Drywall can be used in the area surrounding a fireplace. You will need to use a specific kind of drywall whenever there is a fireplace since the materials typically used to make drywall are combustible and may melt if subjected to high temperatures.

Drywall installed around fireplaces will not catch fire even if it is exposed to an open flame and will not absorb the heat produced by the fireplace itself.

When regular drywall is subjected to the heat from a fireplace, it will often begin to deteriorate quickly as well, which may cause structural flaws in your structure. When subjected to excessive heat, the same materials utilized to insulate the drywall or make it waterproof can catch fire.

Type X drywall, often installed around fireplaces, is designed to liquefy rather than catch fire. This phenomenon can only occur when the material is subjected to several thousand degrees. Drywall is often coated as well, which protects the material from being damaged by any heat or fire.

What is The Drywall Around a Fireplace Called?

The term “surround” refers to the drywall that is set up around your fireplace; it also refers to the framework that is built around the fireplace. This includes the components of your fireplace where the fire is being produced, and it encompasses the mantel, the legs, the returns, and everything that is a component of the assembly of your fireplace.

When discussing the surround of a fireplace, many people make the common misunderstanding that builders and designers are simply referring to the drywall when they mean the surround. Nevertheless, you are responsible for ensuring that the surrounding falls in line with your country’s and state’s requirements.

Many of the fireplaces that homeowners have built have merely had the drywall moved back six inches from the edge of the fireplace, allowing wooden floors and carpets to come right up to the edge of the hearth.

However, because of this, the fireplace is no longer in compliance with the building code since the necessary distance of at least six inches has not been maintained between combustible materials and the fireplace.

Does Drywall Decompose?

Yes, drywall can decompose. In the event that your home was destroyed by fire, you may be debating whether or not to repair or replace the decomposed drywall in your walls. The absolute most risk-free choice would be to have the wall completely replaced.

On the other hand, there are times when something like this isn’t feasible for various reasons. You may relax knowing that mending the wall is another possibility; nevertheless, you should proceed with care if you choose to do so.

Drywall may serve as a fire break due to its high resistance to fire. In most cases, the temperature of a fire pit is not high enough to cause the wall’s strength or integrity to be compromised. As a result, it will continue to fulfill the role of the preventative measure that it was designed to do in the first place.

In addition, repairing the wall is a lot less difficult than you would think it would be. Sanding, filling, and painting should perform the task, considering that the paper is the component that sustains most of the harm.


Even if you choose Type X drywall, which most houses prefer, the best drywall in the world is not completely fireproof. Instead, it’s better to keep things well-spaced and choose materials like concrete or steel that won’t burn or melt well in your fire pit. Keep in mind that it is very hard to put it out once a fire is started.
