Mason-Lite 44" Gas B-Vent Firebox Kits
Have you ever dreamed of the radiant warmth of a masonry fireplace in your bedroom? Or, do you dream of an outdoor fireplace where you can gather together with friends and loved ones? Dreams can come true with Mason-Lite masonry fireplaces. Our factory-built masonry fireboxes are affordable, easy to handle, and consistent in quality. A masonry fireplace adds luxury and increases the value of your home.
Recreating the tradition of the hearth and the elegance & romance of the flame, Mason-Lite captures the essence of the fireplace 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, convenient to Mason-Lite’s California-based production facilities. Pumice is formed when gas-rich, frothy magma rapidly cools, creating air pockets that contribute to its remarkable lightweight properties.
Because it is only half the weight and half the cost of traditional masonry fireplaces, Mason-Lite Lightweight Masonry Fireplace Systems help you realize your dream of having a fireplace in your master bedroom, upstairs retreat, or even your outdoor patio, without major building infrastructure reinforcement. The restful flicker and comfortable glow of the fire will provide you with years of treasured memories.
With the help of ICC-ES, Mason-Lite developed the structural testing and performance criteria (AC375) that would comply with the International Building Code (IBC), the International Residential Code (IRC), and the International Fuel Gas Code (IFGC). This allows building officials throughout the US to confirm that Mason-Lite fireplaces meet these stringent codes.
