4. Wear Beyond Repair:
If the door’s surface has significant damage that cannot be repaired or repainted to restore its fire-resistant properties, replacement may be necessary. Similarly, if the frame or hardware is beyond repair, replacing the entire door will ensure that it continues to meet fire safety standards.
5. Frequent Failure to Function Properly:
If the fire door frequently sticks, fails to close correctly, or shows other signs of dysfunction despite regular maintenance, it may need to be replaced. A malfunctioning fire door could put people at risk, so it’s best to replace it before it becomes a safety concern.

What is an HPL fire door?
An HPL fire door is a type of fire-rated door constructed with High-Pressure Laminate (HPL) as its surface material. These doors are designed to provide excellent fire protection, typically with a fire resistance rating ranging from 30 minutes to 120 minutes, depending on the specific door construction. HPL is a durable, resilient material that resists wear, making it an ideal choice for fire doors in both commercial and residential buildings.
How does an HPL fire door work?
HPL fire doors prevent the spread of fire and smoke between areas of a building. The HPL surface acts as a protective barrier. At the same time, the door's core (usually made from a fire-resistant material such as mineral core or honeycomb) provides the insulation and structural integrity to withstand high temperatures. When a fire occurs, the door expands and seals the gap between the door and the frame, limiting the spread of flames and smoke.
What are the benefits of HPL fire doors?
- Durability: HPL is resistant to scratches, dents, and impacts, making the door long-lasting.
- Fire Protection: HPL fire doors offer excellent fire resistance, ensuring safety during emergencies.
- Aesthetic Appeal: HPL is available in a wide range of finishes, offering a sleek, modern look that complements the surrounding décor.
- Low Maintenance: These doors are easy to clean and maintain thanks to their non-porous HPL surface.
Can HPL fire doors be customized?
Yes, HPL fire doors are highly customizable. You can choose from a variety of colours, finishes, and textures to suit your building's design aesthetic. Some manufacturers even offer the option to create bespoke patterns and designs. Additionally, the doors can be equipped with different hardware, such as fire-rated handles and locks, to meet specific safety requirements.
Where are HPL fire doors typically used?
