The Regency Horizon HRI4E Ceramic Glass Panel – 25 3/4" x 16 9/16" is the exact-fit replacement glass your Regency fireplace insert needs when clarity, safety, and heat resistance matter. I’ve replaced enough cracked and cloudy panels to know this isn’t a cosmetic upgrade—it’s a performance fix. Made from high-temperature ceramic glass, this panel restores a clean, vibrant fire view while standing up to daily burn cycles without warping or failing.
Unlike tempered glass, this ceramic glass panel is engineered specifically for extreme fireplace heat, maintaining strength and transparency up to 1,400°F. Precision-cut for multiple inserts, it seals properly, supports correct airflow, and keeps your unit operating as designed. Manufactured in the USA and compatible with select Regency models, it’s a dependable, long-term solution—especially when paired with a fresh gasket and proper glass cleaner.
