Fire and Smoke

What is a fire door?

After establishing the look and feel of a fire door, and how it can be identical to a standard doorset, what is the actual difference? Like all of the doors made at Lewis Aldridge a solid core is the start of the door, the difference being fire doors hold individual ratings by selecting a FD30 fire door a prevention of the spread of smoke and fire will be prevented for 30 minutes extra compared  to a  standard door. Fire doors are fitted with an intumescent strip along door and door frame, this is an unseen feature which rapidly expands when exposed to extreme heat to seal the gap between door and door frame.
Here at Lewis Aldridge, fire doors can be made to request in FD30, FD60, FD90 and FD120
Fire resistance is one of the most fundamental performance criteria for doorsets, resulting in a complexity of interrelated regulations, standards and guides.
Part B of the Building Regulations sets out requirements related to the escape of building occupants and access for fire-fighters, gradually replacing the Code of Practice BS 5588.
However, insurers and advisory organisations are also particularly concerned with the protection of property, while other application-specific recommendations are also available. Part B refers to fire doors in terms of tests carried out to BS 476, in parallel with a new European standard which will eventually replace it.
It is now generally acknowledged that, in the event of fire, it is smoke that is the major risk to occupants. Lewis Aldridge manufactured doorsets can offer FD30S and FD60S options as well as non-rated. In addition, we can offer FD90S and FD120S performance. Appropriate smoke seals and intumescents are included with our doorsets to suit performance.
