If you're a homeowner or a business owner, you're likely aware that fire safety is of the utmost importance. One way to increase your safety is by installing external FD30 fire doors. For those who may not know, an FD30 door is a fire-resistant door that can withstand fires for up to 30 minutes. In this blog post, we'll discuss what you need to know before you buy an external FD30 fire door. We'll cover everything from the different types of fire doors available, the materials they're made of, the types of glass that can be used, and much more. Read on to learn everything you need to know about external FD30 fire doors.

Types of Fire Doors

There are two main types of fire doors: FD30 and FD60. FD30 doors offer 30 minutes of fire resistance, whereas FD60 doors offer 60 minutes of fire resistance. While external FD60 fire doors offer a higher level of fire resistance, they are also more expensive. Additionally, if your building is smaller, an FD30 door may be sufficient. There are also different styles of fire doors, such as glazed doors or panelled doors. It's important to consider the style of the door you choose, as it will have an impact on the overall look and feel of your building.



Fire doors are typically made of fire-retardant materials, such as engineered timber or a combination of timber and glass. The core of an FD30 fire door is usually filled with a combination of hardwood and particleboard or plywood. Make sure to choose a door that is certified by an independent testing body, such as the BWF-Certifire scheme, which tests the durability and fire resistance of doors. It's also important to consider the thickness of the door, which can affect its fire resistance. An FD30 door should be at least 44mm thick to offer the best protection.


Glass can be an important feature of an external FD30 fire door. It allows natural light to enter the building while also providing a clear view of the outside. There are different types of glass that can be used in fire doors, including wired glass or toughened glass. Wired glass has wires running through it to make it stronger and more fire resistant. Toughened glass, on the other hand, is tempered glass that has been treated with heat or chemicals to make it stronger. Make sure to choose the right type of glass for your needs and budget.



Installing an external FD30 fire door is not a DIY project. It's important to hire a professional who knows how to install a fire door correctly. The installation process involves more than just hanging the door. It includes making sure the door is properly sealed, installing the right type of hinges and locks, and ensuring that there are no gaps between the door and the frame. Improper installation can reduce the effectiveness of a fire door, so it's important to choose a reputable company to do the installation.


Fire safety should be a top priority for all homeowners and business owners. Installing an external FD30 fire door is one way to increase safety and protection in the event of a fire. It's important to choose the right type of door, the right materials, and to hire a professional to do the installation. By following these guidelines, you can ensure that your building is as safe as possible in the event of a fire.
