Chimney & Fireplaces/closing glass fireplace doors with fire burning

Question
Hi Bart,
I just purchased replacement glass doors for my wood burning fireplace.  The manual states the the glass doors should never be shut while a fire is burning, as the tempered glass may shatter.  I often closed the doors on the old unit and have seen others do this as well without any problem.  Is this standard? Are there units available that allow the doors to be closed while burning?

thanks,
Bob

Answer
Hi Bob,

Tempered glass doors should not be closed when the fireplace is operating, however, if you let the fire die down prior to closing and retiring for the evening, you should be able to close them overnight.

Tempered glass will shatter at around 400 degrees.

If you have doors with pyroceramic glass, they can withstand the same temperatures as a wood-burning stove, which are substantially higher than that of a wood-burning fireplace.  Pyroceramic glass is available, but is very expensive.  Most times, pyroceramic glass will cost more than the doors themselves.

Thanks for using AllExperts.Com and good luck with your project.
