Why Does Wood Pop. The holes created by the insects will give the gasses an escape route. Firewood popping occurs when burning wood has a high moisture content.
And, in these moments, the popping and crackling picks up and increases until the moisture in. Firewood popping occurs when burning wood has a high moisture content. When the wood is burned, combustible gasses will be released.
As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas. When temperatures rise and, or humidity levels rise, your wood will expand and if there has been an insufficient expansion gap left around the perimeter of your room, the risk is that the wood will pop up as it expands, because there’s nowhere for it to go. Gas is created by trapped moisture locked in small pockets within the wood.
Normally, when temperatures and humidity levels fall again, your floor will pop back. Once the gas pressure builds up it will create an energy burst with mini explosion. And, in these moments, the popping and crackling picks up and increases until the moisture in.
Typically, when the moisture in the wood is high, the pops and crackling noises are a lot more frequent. When the wood is burned, combustible gasses will be released. As the gas escapes, the fire will emit an audible pop or crack.
In basic terms, it has something to do with the combustion gases escaping from the wood. Some will get stuck in the wood. These gases escape either by an explosion or by finding their way through holes caused by insects.
