Fire-resistant glass door description

Fire-resistant glass in fire-resistant doors, known as grouted fire glass, is composed of two glass sheets bonded together with special fire-resistant strips sealing the edges. The center is filled with a fire-resistant rubber strip, which hardens into an opaque insulting against heat layer when exposed to high temperatures. During a fire, this layer prevents flame spread and thermal conduction to the unexposed side. Consequently, grouted fire glass provides exceptional fire prevention and heat insulation performance       and noise reduction. One of the key advantages of glass fire doors is their ability to achieve a harmonious blend of fire resistance, transparency, and aesthetics.

Fire-resistant glass door vs A normal or standard door

Fire-resistant glass doors, also known as grouted fire glass doors, differ from conventional fire doors in their design. While they share similarities with steel-core glazed fire doors, where the proportion of glazed area increases beyond 30% of the total door surface, the key distinction lies in their construction. The glass panels are bonded together using specialized fire-resistant seals, and an injection-molded, fire-retardant material fills the gaps within the frame, forming a protective barrier when exposed to heat.

In addition to their fire-resistant properties, glass fire doors incorporate aesthetics, allowing for light transmission without compromising on security. They have similar appearance requirements to steel fire doors, with a smooth and flat surface, no visible dents, even paint coating, and absence of defects such as uneven application, weld marks, bumps, or air bubbles. Overall, glass fire doors combine fire protection, transparency, and visual appeal in a seamless manner.
