Fire-rated door is a special type of door that is tested and proven to have a level of fire resistance. Hence, it will not combust (or will take longer to combust) in case of fire. Fireproof materials are used to make HDB fire-rated doors in Singapore that are often used in commercial buildings. When installed properly, this specialty door will make the search operations and fire escape procedure more efficient since the doorway will not be blocked while the incident is ongoing. This is why most commercial interior designers are opting to add fire-rated doors to buildings where many people are gathered on a daily basis.
