Fireplace glass doors are heat-resistant glass barrier between your fireplace and the rest of your home, that can improver safety and efficiency. Glass doors come in a variety of sizes and colors and can be customized to fit your design vision and utility needs. They serve multiple purposes, including preventing sparks and embers from escaping and causing accidents or damage. Glass doors prevent drafts from entering and heat from escaping up the chimney when the fireplace isn't in use. Closed glass doors keep ash and soot contained, which can improve indoor air quality and reduce cleaning.
