Replacement Glass

1 2

A high temperature glass window may be hard to come by from your heating application's original manufacturer. We can help outfit your fireplace with heat resistant tempered glass, or ceramic replacement glass for your wood burning stove!

Tempered glass is seven times stronger than regular glass, with a thermal shock rating of 400°F. This is the safest and most durable glass replacement option for your masonry, factory-built, or zero-clearance doors. Available in different thicknesses with your choice of a clear, gray, or bronze tint. 

We also offer pyroceram wood stove glass! This glass platen option can be used on coal and gasketed stove applications, as well. With a thermal shock rating of 1300°F, our amber tinted glass comes in a variety of shapes and sizes to match your particular heating appliance!

Some important things to remember:

  • Please measure your fireplace or stove glass prior to contacting Fireplace Doors Online. This will help ensure a perfect fit for your application.
  • Glass expands when exposed to high temperatures! Glass sheets need to be at least 1/8" shy of the mounting surface to allow for safe thermal expansion. We are not responsible for breaks due to improper measurements!
  • Metal screws and mounting hardware will also expand under extreme heat! Please do not over-fasten hardware (this helps prevent damage to your glass when your appliance is in use). Fireplace Doors Online is not responsible for breaks due to hardware that has been secured too tightly.

For all of your high temperature replacement glass questions, we have the answers! Give us a call at 1-877-373-6677 and speak with one of our friendly customer service professionals!
