Fire Protective Glass Vs Fire Resistant Glass


Often the two terms i.e. Fire Protective Glass and Fire-Resistant Glass are considered to be the same. But it is not so. They are different in their applicability. For easy understanding, here are certain points that would help differentiate between the two.

Fire protective glasses prevent the spread of smoke and fire, but the heat is transferred to the other side and people can feel it whereas fire resistance glasses not only prevent spread of fire and smoke but also from the heat transfer and the people at the other end cannot feel the heat caused by the fire.

Thus, fire-resistant glass is more effective and protective than a fire-protective glass.
