Recently there has been an increased interest in any product or installation that is supposed to be fire rated, for a good reason. This extra scrutiny has brought to light some interesting things which you should be aware of especially if involved in the installation of fire doors.
Fire doors are not the same as fitting any old door, the importance of getting it right will make the difference between whether it would last 5 or 60 minutes in the event of a fire. There are several components that make up a door set which need to be considered:
1/ The door
Fire doors are rated for either 30 or 60 minutes and are marked up with FD30 or FD60 for easy identification.
2/ Intumescent Strips
These must be fitted to all fire doors as they will swell up when exposed to head to slow the passage of air and fire through the gaps round the door. These intumescent strips are available as fire only or as a fire and smoke option (shown above) which comes with brushes. Gaps above and down the side of the door should not exceed 3mm, with no more than 10mm at the bottom.
Suitable ironmongery which is fire rated and CE marked should be chosen. Complete door sets are increasingly popular for the reason that they come pre hung with compliant hinges and locks.
4/ Door lining
This is arguably the most important part, there is no point of having a nice fire door if the air or smoke can just go round the door. With recent increased scrutiny on the fitting of fire doors, it has come to light that there is only one fully tested and accredited fire door installation method currently available on the market. See below:
This foam is the only one on the market that has been independently tested in all common configurations giving peace of mind and removing any issues with compliance.
When used with the Blue60 fire rated packers it will give 60 minutes of fire protection to timber doorsets without the use of extra mastics or sealants.
