So what precisely is a fire door, we clarify!

By Ian Richardson


Outlining a Composite Fire Door

For door makers and customers there have, for many years now, only been two main types of door; hard wood and UPVC doors, and up to this point these options have proven to be more than adequate for regular demand and wants.

As the general purchasing public interest in the advanced wishes as well as demand started to extend though it looked that a new material was needed which would fulfil a number of criteria: It would need to look aesthetically pleasing, have a longer guarantee than either of its forebears, would need to have a low upkeep obligation so as to suit the busy lives of owners who don't always have the time (nor wish) for continued and lengthy door care and upkeep, it would help in reducing energy costs and carbon footprints by being energy efficient and most importantly of all it would need to be secure in the event of a fire.

Hence the necessity for composite fire doors

Prior to any safety rating a Composite door is, as the name might suggest, the composition of a hybrid of materials which are specially formed to simulate the appearance of a traditional hardwood door whilst keeping the absence of upkeep which has always been typical of a UPVC door. They are proven though to outlast their wooden counterparts with virtually not one of the maintenance wants. Whilst the actual materials which are used are subject to change from manufacturer to manufacturer a Composite Door often consists of wood, PVC, insulating materials and an external layer of GRP, which is simply a second name for fibreglass. This GRP layer is can be colored, stained and textured and then finished with ridging and profile to give the overall effect and look of a typical hardwood door.

Why buy composite fire doors?

Because of their layer of insulation and GRP layer Composite fire Doors make a good door choice, particularly in a domestic setting where their classy appearance would suit any number of themes or existing dcor. They are also well-liked for business use, particularly where the right door creates the right impression for visiting clients and consumers.

In order to be catalogued as fire doors all Composite fire doorsmust be at least 44mm thick and are required to have been tested and cited to a fire rating of FD30 implying that they give integrity and insulation for 30 minutes in a fire situation. This is the minimum legal requirement of a fire door and whilst doors which are reserved for the home have no statutory responsibility or need there are apparent security worries which is exactly why many homeowners also choose to have fire prevention techniques such as Composite Fire Doors.
