Fire-Resistant Glass
Fire-resistant glass is a specialty glass that can withstand flames and heat in the event of a fire. It also prevents fire spread and allows people time to evacuate safely.
Applications
• Non-fire-rated glass (E-Grade)
- Fire-resistant door (Fire resistance certification),
- Non-fire rated fire-resistant window (20 minutes, certification test results)
• Fire-rated glass (EI-Grade)
- Inner partition (Fire resistance certification),
- Exterior curtain wall (Fire resistance certification)
Color
• Clear
Specifications
• Non-fire-rated glass (E-Grade): 2,500 x 2,500mm
• Fire-rated glass (EI-Grade): 1,500 x 3,000mm
Glass prevents flame spread in the event of a fire. As it does not have the ability to resist heat, it is used in fire resistant doors and windows. HANGLAS's fire resistant glass brand is “PYRO-VISION.”
Glass prevents flame spread and blocks radiation in the event of a fire, which prevents secondary fires and allows people time to evacuate. Fire-rated glass is classified based on its fire resistance duration, EI30 (30 minutes), EI60 (60 minutes), EI90 (90 minutes), EI120 (120 minutes). HANGLAS's Fire-rated brands are “FLAMSTOP” and “CONTRAFLAM.”
Fire-rated glass is fire-resistant glass that can be applied to inner partitions and exterior curtain walls, and it has been certified by Korea Institute of Civil Engineering and Building Technology. Double Low-E glass is used on exterior curtain wall to enhance insulation.

Precautions for Fire-Resistant Glass Installation
1. The manufacture, testing, and inspection of fire-resistant glass doors shall comply with KS F 3109 (Door Sets). In accordance with relevant regulations, fire-resistant glass and frames must be installed as a complete system.
2. Verify that the frame pockets match the drawings. Should discrepancies exist, corrective and supplementary work must be undertaken.
3. Prior to commencing work, remove any debris or other obstructions from within the frame into which the fire-resistant glass will be inserted.
4. The space between the fire-resistant glass and the frame must be filled using a fire-resistant sealant that has received domestic and international fire resistance performance certification.
5. Any contaminants adhering to the fire-resistant glass or frame must be wiped off immediately using clean water or a suitable solvent.
6. Welding sparks and grinder sparks must absolutely not come into contact with the glass surface, and silicone curing must be allowed for at least 48 hours.
