FireBrick Inserts

Step 2 Choose your insert

What to consider? Height: We’ll start by choosing the tallest insert that fits into your fireplace opening.

We make other suggestions based on usage. Usage: How big is the room? How much heat do you want? How long would you like the fireplace to run? The answers may point to an insert with more or less heat output.

Step 3 Cover the gap

We use a matching metal surround to cover the gap between the insert and your fireplace opening.They come in three fixed, non-adjustable sizes that overlap the space, and then some. Some fireplaces—like those with arches, unusual configurations, protruding stonework, etc.— may require a custom-made surround. Surrounds are available in aged brass, black, graphite and new bronze.
