What Are Fire-Rated Doors? FD30 and FD60 Explained

Fire safety is a crucial part of any home improvement project—especially when replacing internal doors. If you’re upgrading doors in your home, you’ve probably come across terms like FD30 fire doors and FD60 fire doors. But what do they actually mean? How do fire-rated doors work? And when are they required?

At The Door Line, we supply and fit a wide range of certified LPD fire doors, offering homeowners across Leeds and West Yorkshire a safe, compliant, and stylish solution. In this guide, we’ll explain everything you need to know about fire-rated internal doors, including construction, ratings, regulation requirements, and how to choose the right fire door for your home.

What Is a Fire-Rated Door?

A fire-rated door is a specially designed internal door engineered to withstand fire and smoke for a specified amount of time. Fire doors help to:

• Slow down the spread of flames

• Provide critical escape time

• Protect hallways, staircases, and exit routes

• Contain smoke to reduce damage and increase survivability

Fire doors are not just thicker doors—they include specialised materials, intumescent seals, heat-resistant cores, and fire-rated ironmongery.

They are an essential safety feature in both domestic and commercial properties and are a legal requirement in many homes.

What Does FD30 and FD60 Mean?

The “FD” rating indicates the fire resistance duration of a door.

FD30 Fire Doors

FD30 fire doors provide 30 minutes of fire protection.
They are the most common fire doors used in residential properties across the UK.

FD60 Fire Doors

FD60 fire doors provide 60 minutes of fire protection.
They are typically used in larger homes, commercial buildings, or areas where additional protection is required.

Both types undergo rigorous testing to meet British Standard BS 476 Part 22 or EN 1634-1 fire resistance testing.

How Are FD30 and FD60 Fire Doors Constructed?

To achieve their fire rating, fire doors include:

• Solid or engineered cores such as particleboard, chipboard, or composite materials

• Intumescent strips that expand during heat exposure to seal gaps

• Fire-rated hinges, closers, and hardware

• Heat-resistant glazing (in the case of glazed fire doors)

• Thicker frames and specialised fire door linings

LPD fire doors, supplied and fitted by The Door Line, meet all relevant safety certifications and offer high-quality construction combined with stylish finishes.

When Do You Need a Fire-Rated Door in Your Home?

In the UK, Building Regulations specify where fire doors are required. Common scenarios include properties with:

• Three or more storeys

• Loft conversions

• An internal garage leading into the property

• Commercial or mixed-use areas

• Escape routes or communal stairwells

If you’re unsure whether your home needs FD30 or FD60 internal fire doors, The Door Line’s pre-order measurement and compliance service ensures you select the right specification.

Are Glazed Fire Doors Safe and Legal?

Yes — as long as they use fire-rated glazing.
Certified glazed fire doors still achieve FD30 or FD60 ratings and allow more natural light into spaces such as:

• Hallways

• Kitchens

• Living areas

• Landings

LPD’s glazed fire door range includes multiple styles, from modern clear-glazed designs to traditional panelled options.

FD30 vs FD60: Which Do You Need?

Choose FD30 fire doors if:

• You live in a standard two-storey or three-storey home

• You need door upgrades for hallways, lounges, bedrooms, or kitchens

• You want safe and affordable domestic fire protection

Choose FD60 fire doors if:

• You have a larger property or commercial premises

• You want extended evacuation time

• Building Regulations in your project specifically require FD60 protection

The Door Line’s experienced team can assess your layout and recommend suitable fire ratings.
