Mason Lite 39 inch Natural Gas B-Vent Firebox Kits MGFP39 Product Details

Recreating the tradition of the hearth and the elegance & romance of the flame, Mason-Lite captures the essence of the fireplaces masonry artists have been crafting for centuries. And, with a proven history of superior quality, lightweight fireplaces for indoor and outdoor projects, it’s no wonder Mason-Lite is one of the industry leaders of modular concrete fireplaces.

At Mason-Lite, we use the finest aggregate materials available to build our lightweight modular concrete fireplaces. One of the main ingredients is pumice, a naturally fired volcanic rock with tremendous strength. Its lightweight attributes are second to none, and because of its pre-fired beginnings, pumice retains heat better than any natural aggregate available. The best sources for USA pumice are in the western states, which are convenient to Mason-Lite’s California-based production facilities.
