   *Not ordinary tempered glass. It is special heat tempered. Maybe trade named Pyrex. You will probably have to order it through a fireplace shop anyway, so you might as well get them to measure and install it, too.

   *Is there another method other than heat tempering? I thought it was different glass too...till I blew our windows out last winter. When I tried to order special glass he leaned over the counter and said" we used to supply Heritage with glass...it's just tempered". If it is a specialized tempering process please let me know so that I can shriek at them...and mabee get a better discount on my next tempered order.

   What you are looking for is a special glass. Common tempered glass will not withstand heat generated by fireplaces. Pyrex as mentioned above is a brand as is Neoceram. Should be available at a fireplace dealer, or check your local Glass Shop. If you can't locate it there, it is marketed to retailers by Technical Glass Products(TGP) out of Seattle, WA. Sorry don't have their number, could try !-800 Directory. One thing I do know is that it is very expensive - About $40.00 sq.ft.

   I meant to say heat-proof tempered. It is different than ordinary tempered. Just go down to your local store and buy a glass coffee pot. Put it on one burner of your stove. Now put a piece of ordinary tempered glass on the other. See what happens.

   *Sir,Clear tempered glass used in fireplace doors is heat tempered. All glass door manufacturers that use clear tempered stipulate that doors are to remain open during use. Fireplace temperatures can eventually remove the temper from the glass,, ultimately reducing it ti a state of extreme fragility.If you are installing a fixed panel, Pyrex may also prove to be inadequate. In the fireplace industry, its use is generally restricted to gas stoves etc., and often to narrow strips instead of large panels. Pyrex also has a rippled appearance.Neoceram or Robax etc. are high temperature panels. They are expensive. They will certainly take the heat, but are not to be considered unbreakable. These products are used in wood stoves and gas stoves. In woodstoves, many a piece has been broken by a log rolling against it.Why are you installing this? Generally when someone wants to do this to a see-through it is because it is not venting properly. Is this the case?I would recommend a fireplace door from Portland-Willamette or Design Specialties. A dealer can determine correct size and materials. Units will be divided into two or for panels, making glass replacement less of an issue (you probably won't break them all at once. And youwill be able to open it up to clean it.Good luck.

   I'm dealing with a 1950s brick fireplace that is open on two (adjoining) sides. I want to close off one of the two sides with glass. What is the best kind of glass to use?
