What are fire rated windows?
Similarly, you may ask, what makes a window fire rated?

Additionally, do windows need to be fire rated? Unprotected areas External doors and windows may need to have fire resistance and (in the case of doors) be self-closing or (in the case of windows) be fixed shut to limit the risk of fire spread between adjacent properties.
Considering this, what is the fire rating of 1/4 tempered glass?
|Fire Rating||Application||Max CV W|
|20 Minutes||Wood Door||36-1/8"|
|20 Minutes||Aluminum Door||36-3/4”|
|20 Minutes||Steel, Wood and Aluminum Sidelites*, and transoms*||96"|
|20 Minutes||Steel Windows*||96"|
Is Tempered glass fire resistant?
Tempered glass, which is heat-treated to make it about four times stronger than regular glass, is also effective. Though they don't provide visibility, glass blocks are extremely fire-resistant while still providing light. Perhaps the best is wired glass, which is tempered glass with metal wire reinforcement.
