In the UK, fire doors require inspection at least every six months, as specified in BS 9999. For high-traffic environments like schools, hospitals, and similar facilities, it’s smart to conduct checks even more frequently. This isn’t just about satisfying compliance; catching damage or issues early can prevent bigger headaches later.

What are fire doors made of? They are built with strong materials like solid wood, gypsum, or steel that can handle high heat. Heat-activated seals around the edges expand in a fire to block gaps. Some fire doors also have special glass that stays strong in heat. The outside can be finished with wood veneer, paint, or laminates, just as long as they meet fire safety rules.

Landlords need to install, inspect, and maintain compliant fire doors under the Regulatory Reform (Fire Safety) Order 2005 and Building Regulations. Tenants need to use the fire doors as intended and report any issues promptly, but they’re not authorized to make changes or replacements themselves.

Fire doors are generally about 44 millimetres thick to do their job against fire. The normal sizes you'll see are 1981mm by 686mm for bathrooms and storages, 1981mm by 762mm (that's two foot six inches) which is the most common internal door, and 1981mm by 838mm for wheelchair and disability access. FD30 fire doors, come in the imperia and metric sizes. FD60 fire doors, are usually a thicker at 54 millimetres and can withstand fire for 60 minutes.

Fire doors prevent fire and smoke to a specific area, preventing them from spreading throughout the premises. This containment is vital, as it preserves escape routes and provides occupants with extra time to evacuate safely. In addition to protecting people, fire doors help minimise property damage and ensure that the building remains compliant with current fire safety regulations.

Hollow core doors are lightweight, cost-effective, and ideal for interior use in low-cost projects, but offer poor insulation, soundproofing, and security. Semi-solid core doors, with a foam core wrapped in MDF or plywood, provide a better balance of cost, durability, insulation, and soundproofing, making them suitable for residential and commercial spaces. Solid core doors, the most expensive and heavy option, offer superior security, durability, insulation, and soundproofing, making them the best choice for high-traffic areas and locations requiring high security and privacy.

Different types of fire doors are available based on various factors such as their fire resistance (FD30-FD120, higher ratings for higher-risk areas), materials (steel, wood, glass), finishes (pre-finished, unfinished, primed), style (single or double), and closing mechanisms (self-closing, automatic, power-operated). You should choose the right door depending on the building’s fire safety needs.

Pre-finished doors are ready to install. They offer a durable, factory-applied finish. They're convenient and professional-looking, but more expensive and less customizable. Unfinished doors are bare wood. They provide a complete customization but need time, effort, and skill for sanding, priming, and finishing. They are the most cost-effective option. Primed doors offer a middle ground. They’re pre-coated with primer for easy painting. They save time and effort compared to unfinished doors while still allowing for custom colours, but require a final coat of paint.
