Direct Vent Technology

With Direct Vent fireplaces and inserts, 100% of combustion exhaust and fumes are removed from your home. These sealed fireplaces provide optimal heat, conserve energy and ensure clean, safe indoor air quality.

FireBrick Technology

FireBrick is an energy-saving firebox technology used in gas fireplaces and inserts. FireBrick produces up to 25% more radiant heat than metal fireboxes—heating rooms faster and using less fuel. This increases efficiency and reduces heating costs. FireBrick is molded from layered ceramic materials in a variety of seamless masonry designs.
