Enjoy an indoor or outdoor fireplace year-round!

Whether you dream of having an indoor traditional fireplace in your upstairs master bedroom retreat or on your outdoor patio, you can accomplish it without major building infrastructure reinforcement. This is because the Mason-Lite Lightweight Masonry Fireplace is half the weight and half the cost of traditional masonry fireplaces.

These modular concrete fireboxes are the lightest in weight in their class with the highest heat resistant strength on the market. A key advantage of prefab outdoor fireplace kits is the rapid installation. Often, you can install these fireplace models right away, which means you can start using and enjoying them promptly after purchase.

Fireplace Kit Specs

  • The fireplace façade can be finished with brick, marble, tile or stone, typically at a thickness of 1¼”: 
  • The exterior may be finished with the same noncombustible products, including wood siding as long as proper clearances from combustible materials are adhered to according to the installation instructions.
  • The prefabricated fireplace system meets or exceed all federal, state, and local construction building code requirements and are certified for both indoor and outdoor installation

Optional Firebrick Panels

To ensure the longevity of your fireplace all of our Mason-Lite units require a firebrick liner. The firebrick panels add a classic look to your fireplace and efficiently reflect more heat into your living space.  A typical firebrick lining takes a Mason five to eight hours of labor to install but the Mason-Lite prefabricated firebrick panels install easily in a matter of minutes.

The set consists of two sides, a back and a bottom that fit the standard firebox sizes of 33″-63″.

Chimney Design

The Mason-Lite fireplace construction has been tested with both a masonry chimney, manufactured by MFI, and a Class A listed metal chimney. Either chimney system will work.

When installed, the maximum overall height of the Mason-Lite fireplace design is 40 feet. The minimum chimney installation height is 14 feet, given that the chimney is straight. If the chimney is not straight, the minimum installation height is 17 feet.
