Fire-resistant glass is a particular type of glass that prevents flames, smoke, and heat from passing to the non-fire side.

It is classified as E, EW, and EI. The duration for which the glass can maintain its protective properties (in minutes) determines its classification.

E class fire-resistant glass maintains its integrity within its frame without allowing flames or smoke to pass through.

For example, E30 fire-resistant glass will maintain its integrity for 30 minutes. EW and EI class glasses, in addition to blocking flames and smoke, also partially or fully prevent the passage of heat.

Another example, an EW60 glass will partially block heat while completely stopping flames and smoke for 60 minutes. An EI90 glass will fully block heat (so much so that it will be possible to touch the glass during a fire), and will also completely stop flames and smoke for 90 minutes.

Technical Features
Applications

Fire-resistant glass is part of a fire protection system. It cannot be used with just any frame. It must be used within frames appropriate for its class. If requested, Alcam not only provides glass supply but also offers system solutions with frames, thanks to its expertise and partnerships.

Windows and doors in all buildings with high human traffic (schools, hospitals, government offices, workplaces, hotels, restaurants, shopping malls, etc.)
