35mm Fire Doors, What Differentiates Them and how to Install One
While 35mm fire doors are an absolutely important element of any house or building, choosing the best one can be a hard task. If you are looking for one, here is a complete guide that explains what you need to know about purchasing and installing these doors.
The difference between fire door and standard interior door
Manufactured with a solid core construction, a fire door offers a different level of protection against fire. They come in a variety of ratings that shows how long they can withstand flames and heat. FD30 rating is the minimum rating of such doors offering a 30 minutes resistance. However, there are also higher specifications of doors such as FD60 that provides protection and additional time. Since fire doors alone cannot offer the necessary protection, to improve their effectiveness you must install the correct door hardware according to the fire door regulations.
These doors generally work by fitting intumescent strips around the dormant edges of the door. However, when these edges get into contact with heat, they rapidly expand, thereby sealing the space between the door frame and the door and create a shield against fire. To ensure that the smoke does not get through the door, you can install intumescent strips with seals. For a fire door to prevent the spread of fire, protect any escape route and restrict the quantity of oxygen getting in, it must be installed properly and kept closed

Apart from the door, the ironmongery and the frame are also just as important. This is because they all work together seamlessly. While shopping for one, make sure that you buy only compatible components and hardware. When you consider the cost of loss of life and damages that occur during fire outbreaks, saving a few shillings isn’t worth it. At all times, ensure that you ask for installation instructions, stick to the specification and follow them well.
