A cracked or cloudy side panel ruins the fire view fast—and I’ve replaced enough stove glass to know it’s not something you should ignore. This Napoleon NPS40 ceramic side glass panel is a precision-cut replacement designed to restore clarity, safety, and performance to your pellet or gas stove. Made from high-temperature ceramic glass, it handles extreme heat while keeping your firebox view sharp, clean, and distraction-free.
Rated to withstand temperatures up to 1,400°F, this USA-made panel is a direct OEM replacement for Napoleon part W300-0037, which means proper fit and peace of mind during installation. If your stove relies on side viewing windows, this glass brings back that clear, cozy glow without compromising durability or efficiency. Pair it with a fresh gasket and a good glass cleaner, and your stove will look (and perform) like it should.
