World-Class Function Meets Aesthetic Design

This vent-free fireplace is the perfect way to add atmosphere to your home, without having to worry about adding a chimney or ventilation. Our vent-free fireplaces weigh significantly less, cause less heat loss, and can be installed in nearly any space. We have several models of our vent-free fireplace: The original vent-free, vent-free see-through, and the vent-free light. The latter is a lighter-weight option that has a shallower firebox, allowing for lighter components and easier masonry work.

The vent-free fireplace can be used indoors or outdoors and can accommodate almost any veneer, mantle, or surround. Additionally, our firebrick comes in a number of colors and thicknesses to accommodate a variety of firebrick patterns and designs.
  • The vent-free comes in sizes 30”, 36”, 42”, and 48”; the vent-free lite comes in 36” and 42”
  • Can be installed directly on a wooden or other combustible floor material, which makes it ideal for remodeling projects
  • Can be used only with unvented decorative gas logs
  • Vent-free lite is available with a straight back configuration
  • Vent-free firebox styles include conventional and see-through
