Astria

Astria, formally Lennox Hearth Products, offers two different outdoor fireboxes: a basic prefab builder box and a high-end prefab box with several different interior brick options.  Their mosaic selection is made up of actual firebrick, which gives the fireplace the look of a true masonry fireplace, while it is a prefab box at a fraction of the cost of a full masonry fireplace and chimney.
