It measures 21 inches by 11-3/4 inches by 1/2 inch and is marketed as a ceramic fiber alternative capable of withstanding very high temperatures.

Why selected: broad compatibility and simple cutting enable a practical retrofit without ordering a highly specific OEM part.

Buying Guide

  • Which size fits your space? Match BTU ranges and square-foot coverage to your room dimensions. Larger rooms benefit from higher BTUs and efficient flame view, but oversized inserts can waste heat in smaller spaces.
  • What fuel type suits your home? Wood-only inserts deliver classic ambiance and high heat, while pellet models offer steadier ignition and longer burn times with cleaner handling. Consider maintenance needs and fuel availability.
  • How important is a clear view? If the double-sided glass or viewing window is a priority, choose models featuring larger windows and stable glass performance under heat.
  • Are seals and gaskets important? Regularly inspect and replace seals to prevent smoke leakage and drafts. Self-adhesive gasket tapes can simplify maintenance for DIYers.
  • Installation flexibility? Some inserts offer trim kits and adjustable frames to conceal gaps in larger openings. Ensure compatibility with your existing chimney and framing before purchasing.
