#QUICK QUOTES PREMIER ALTERED KITS FULL#
If this process remains unresolved and is repeated, as well as the annoyance and the potential for harm, the damage will occur voiding the doors certification and a full replacement would be required. If the self-closing mechanism has been altered to accommodate the vacuum present and the air balance is neutralised by the opening of a window or door in the vicinity, the fire door will dangerously slam shut to the extent of shaking the lining and potentially damaging the surrounding area.
However, this is not ideal or advised as the fire door generally shuts at an excessive dangerous speed to ensure the latching mechanism is engaged. We generally see clients wanting to speed up the closing or latching speed of the doors self-closing mechanism, this appears to resolve the issue. Resulting in the fire door unable to perform as it was tested and manufactured for if it was exposed to fire. If a vacuum is present when a door attempts to close, there is an inadequate amount of air transference between the two rooms causing the vacuum and at the final stages of closure, the door appears to bounce of its rebate and not fully latching. Within a small room we commonly find that the air balance is marginally different between the small room and the other side of the fire door. There might be more to your fire door not closing than you first thought.Ī vacuum being present is a common issue we face at the front end of our supply and installation projects.
The explanation is to show everyone the problems involved in fitting a fire door within a small room.
