The Best Heat Resistant Barrier for Fire Pit in 2021

Are you looking for the best heat resistant barrier for your fire pit? Look no further, because we’ve got the perfect guide for you!

The fact of the matter is that fire and wood don’t mix well, except when the wood is being used as fuel for the flame. Fire will also always win over wood, which makes many people skeptical about getting a fire pit on their wood deck.

Although whether your decking is made of concrete or composite wood, it is always a good idea to protect them from the heat of the fire. This is where a heat resistant barrier for a fire pit can come in useful!

Heatproof or thermal barriers can ensure that your wood or concrete structure is shielded from the heat of the fire pit. This barrier lets you use fire pits safely even when it is placed on wood decking.

How Hot Does a Fire Pit Get?

Before jumping into some of our top recommendations, let us first understand exactly how hot a fire pit can get. According to Sciencing, a bonfire or fire pit can get as hot as 2,012 F or 1,100 C.

This is a pretty high temperature that is enough to melt even certain metals. As such, it can definitely be dangerous for the deck around your fire pit if you don’t prepare the necessary heat resistant barrier.

FAQs About Heat Resistant Barrier for Fire Pit

How do I protect my deck from fire pit heat?

The deck can be a very cosy place to hang out with friends and family, especially if you have a fire pit to gather around! But when you’re trying to build a fire pit in your home, it is important to choose a gas-fuelled pit and install it properly.

Then, your deck will have to be strong enough to hold the fire pit, so it can be crucial to design a sturdy and resistant structure. This includes building a no-burn zone around the fire pit and placing it away from flammable furniture. You will need a heat resistant barrier or surface to catch any embers and resist the heat.

What is the best material to put under a fire pit?

One of the best materials you can place under a fire pit is rock. Hard rocks that are dense and less absorbent of water can be great, such as granite and marble. Meanwhile, soft rocks like lava glass or poured concrete can be a great alternative too.
