A fire pit liner, also known as a fire pit surround or insert, is a tough metal shield. It safeguards the stones, bricks, pavers, or concrete used in constructing a wood-fueled fire pit from the scorching heat and fierce flames.
Made of durable high-temperature resistant steel, this liner is installed with a small gap between it and the fire pit material to shield against cracking, crumbling, or exploding.
While a fire pit doesn’t necessarily require a ring insert, it is highly recommended to use one for the longevity and aesthetics of your fire pit.
Now, for permanent fire pits built with fire bricks, a liner is generally unnecessary. Fire bricks are built to withstand high temperatures, eliminating the need for an additional liner.
However, when using materials like pavers, bricks, or cinder blocks for your fire pit, including a liner is a smart move.
These materials can be somewhat delicate when exposed to intense heat, potentially cracking, crumbling, or even exploding.
This is because the trapped water inside them can evaporate and expand, leading to such issues. By incorporating a fire pit liner, you establish a protective barrier between these materials and the flames, minimizing the risk of damage.
A fire pit liner not only offers protection but also adds a touch of style. It provides clean and polished edges, enhancing the fire pit’s overall appearance.
These liners typically sport a smooth and sleek black finish, adding visual appeal. This is usually a heat-resistant coating, adding an extra touch of charm to your fire feature.
Fire inserts come in various designs, sizes, shapes, and thicknesses. They typically range from 20 to 50 inches in diameter.
Customized options are available at a higher cost if desired. If you want a liner that will endure and provide peace of mind, look for a thick steel gauge, preferably around 10 gauge or thicker. This ensures adequate thickness and durability for your fire pit liner.
When selecting a fire pit liner, start by measuring the inner diameter of your fire pit to determine the appropriate insert size.
Look for inserts that come in as few pieces as possible for easy assembly and a better fit. Consider the desired look and ensure the insert matches the dimensions of your fire pit for a proper fit.
Fire pit liners are available in various shapes, both round and square. Custom options are also available but at a higher cost if necessary.
The depth of the liner will also factor into the type of material you use inside ie: a deep liner will not be suitable to have glass fire pit stones inside for visual effect as it will need too many and be very costly.
