Fire-Rated Glass FAQs
There are two classifications for fire protection when it comes to glass doors and walls. Fire integrity refers to the ability of the glass to stop the progress of fire and smoke, while fire insulation refers to its ability to prevent heat from moving to the other side of the partition.
Category E is for integrity only, preventing the spread of fire and gases (including smoke) but not the transfer of heat through the glass.
Category EI is for both integrity and insulation, offering the highest protection against flames, smoke, and heat so that people can evacuate safely in the event of a fire.
Fire-rated glass is rigorously tested in a controlled environment to determine its rating. The rating will be listed in minutes; for example, E30 fire-rated glass should maintain its integrity against flames and smoke for at least 30 minutes.
At Glass Interiors, we provide fire-rated glass certified EI30 and EI60, which provide full integrity and insulation protection for 30 or 60 minutes respectively. They also come with an acoustic rating of 62 decibels, for the added benefit of soundproofing.
Fire-resistant glass can withstand temperatures hundreds of degrees higher than standard toughened glass. It uses multiple thin layers of toughened glass to slow the spread of fire – giving people more time to get out of the building and making it easier and safer for firefighters to put the fire out when they arrive.
Fire-rated glass doors and partitions do the job of regular glass in dividing spaces and improving aesthetics, but they have the added function of trapping flames, smoke, and heat inside the partitioned area for at least 30 minutes. Not only does this save lives, but it also limits damage to the building and reduces repair costs.
The TG100 fire-rated glass system available from Glass Interiors offers high levels of protection without compromising on looks. Its 30mm deep section offers a slimline appearance and is available up to 3m high for fire glass walls and doors. They can be used both internally and externally to keep buildings safe.
Fire safety should be a priority for any building used by a large number of people, such as employees, visitors, and members of the public. While not all glass partitions and doors need to be fire-rated, it’s crucial to install fire-rated glass where necessary.
Typical areas where fire glass should be used include entrances and exits, stairwells, and any other escape routes from common areas. Consult the building regulations for your region to find out where fire-rated glass must be implemented to comply with the law, and where glass should be both integrity and insulation protected versus places that the glass can be integrity-only.
Fire-rated glass partitions and doors should be appropriately tested and should only be installed as part of an approved fire safety system. Never risk reduced effectiveness in the event of a fire by attempting DIY installation. Fire glass should always be fitted by a specialist, such as Glass Interiors, to ensure a professional-standard installation that's completely in line with building regulations.
