Fireplace Glass & Ceramic Glass Rated to 1,400°F for Ottawa Valley
Get the glass that can take the heat. Raw Glass Inc fabricates glass-ceramic fireplace glass rated to 1,400°F — the hearth industry standard for sealed, closed-burn appliances like wood stoves, inserts, and gas fireplaces.
Why Fireplace Glass Needs to Be Ceramic, Not Tempered
Closed-burn appliances — wood stoves, fireplace inserts, and sealed gas units — routinely reach heat levels at the glass face that standard tempered glass isn’t built to handle. Tempered glass is rated for continuous exposure to roughly 470°F and is intended for open-faced fireplaces where doors are opened during a burn. Ceramic fireplace glass, by contrast, is built to withstand the sustained, higher heat of a closed-door appliance without cracking — which is why every wood stove and insert manufacturer specifies ceramic glass for sealed doors. Choosing the correct glass type isn’t just about performance; it’s about safety and keeping your appliance’s certification valid.

Frequently Asked Questions
Can I use regular tempered glass in my wood stove?
No. Tempered glass is only rated for the lower, intermittent heat of an open-faced fireplace and isn’t built for the sustained high heat a closed-door wood stove or insert produces. Using the wrong glass type is a safety risk and can void your appliance’s certification.
Is ceramic fireplace glass the same for every stove or insert?
The rating (1,400°F) is standard, but the size and shape need to match your specific appliance. Bring your door’s dimensions or the old glass for an accurate custom cut.
Do you replace broken or cracked fireplace glass?
Yes, Raw Glass Inc fabricates custom-cut replacement fireplace glass to fit your existing door or unit.
Do you supply glass for gas fireplaces as well as wood stoves?
Yes. Ceramic fireplace glass rated to 1,400°F is used in sealed gas fireplace units as well as wood-burning stoves and inserts.
