How Are Fire-Rated Windows Different Than Ordinary Windows?

Fire-rated glass is manufactured to withstand high temperatures caused by fire and withstand the impact pressure caused by high-pressure fire hoses. The glass undergoes a rigorous testing process and at the end is awarded a fire-rating ranging from twenty minutes to three hours. The time correlates with how long the glass lasted.

What is the Difference Between Fire-Protective and Fire-Resistance Glazing?

Fire-protective glass helps slow the spread of flames and smoke by using materials like wired glass, glass ceramics, and specially tempered glass. Fire-resistance glazing adds an additional layer of protection by blocking radiant and conductive heat from transferring. 

Are There Things I Should Look Out For When Choosing a Fire-Rated Window?

Some fire-rated windows available on the market have extensive disclosures, which when read, essentially make the fire-rated glass worthless. An example would be one which states the glass does not meet the blast requirements or one which is fire-rated from one direction. In either of those situations, the glass won’t hold up against the potential situations you are purchasing it for. The team at American Thermal Window will help ensure you get high-quality fire-rated glass for your fire-rated windows.

What is the difference between Category I and Category II fire-rated glass?

Category I fire-rated glass can withstand an impact of 150 pounds per foot. Category II can withstand 400 pounds per foot.
