Yes, fire-rated glass doors are available. These doors are made from specially treated glass that can resist fire and are often used in areas where visibility is needed without compromising safety.
How does the core material affect fire door performance?
The core material significantly impacts the fire door's fire-resistance rating. For instance, doors with a honeycomb core are lighter but may have lower fire ratings than those with solid cores made from gypsum, which offers better insulation and fire resistance.
Are there any regulations regarding fire door materials?
Fire doors must comply with various building codes and fire safety regulations that specify the materials and construction methods used to ensure they meet specific fire-resistance ratings.
How can I determine if a fire door is made from the right materials?
Look for certification marks from Underwriters Laboratories (UL) or the American National Standards Institute (ANSI). These marks indicate that the door has been tested and meets the required safety standards for fire resistance.
