Fire, Smoke and Weather Sealing for Door Assemblies
I need to buy a 30 minute fire seal - which product should I buy?
First of all, please do remember that adding a fire seal to any door doesn't automatically make it a fire door. Do make sure that you have a properly tested fire door construction.
Also, please remember that not all fire doors are the same - so there's no single answer to this question! The first thing to check is the door manufacturer's test evidence for the door you have - whatever type and size (or sizes) of seal they have tested with is what you should buy.
Where door manufacturer's test evidence isn't available, the usual recommendation is to use a 15 x 4mm seal, fitted centrally at the head and both jambs of a single leaf, single acting door. (If you are in any doubt, or have a particular application you would like to discuss, please contact our Technical Services team on 01626 834252 for details).
If it's a fire and smoke door (which will be denoted FD30S), then do also remember that a fire seal alone will not be sufficient - you should purchase a combined smoke and fire seal, such as the Lorient DS. Don't forget to seal the threshold too - you may find our FAQ on threshold sealing helpful.
