Adding a fire seal to a standard door does not make it a fire door, a tested constructed fire door is compatible with our fire seals.
There are a variety of fire doors out there that require different specifications, so not one individual seal is the solution. Find your doors test evidence to discover the type of door that needs to be specified – whatever type and size (or sizes) of seal they have tested with us 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 01223 832 851 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, with a threshold seal.
Painting over smoke seals will compromise smoke containment performance, however over painting fire seals should not compromise performance in a fire situation. Sealmaster can provide a powder coating option for your seals, subject to a minimum charge.
A threshold plate is a good idea, for several reasons:
The simple answer is to check the door manufacturers’ specification and test evidence. If they have protected ironmongery then you will also need to; if not, then you are clear to work without it. In best practice, ironmongery products are described as ‘hot spots’ in a door.
The best way to protect against early failure is to either put a layer of intumescent behind the hinge or wrap the ironmongery in a thin layer of intumescents. This is known to be an excellent insulator and resists the passage of fire through the affected area.
You should follow the door manufacturer’s instructions regarding intumescent seals. It is important to use the type, dimensions and location of seal that is detailed, as a change to any of these could negate the likely fire resistance performance of the doorset.
The cold smoke rating has now been formalized into the BS 5588 standard.
This ‘S’ decal is used in the FD rating; for example, FD 30S means the fire door has a minimum of 30 minutes resistance AND a smoke sealed door. For smoke seals here we are talking about ‘cold smoke seals’ which handle smoke which has moved away from the fire.
More than half the ratings are now required to be the latest ‘S’ type door which under the British Standard 476 Part 31:1 criteria. The seals must be able to perform to a minimum leakage rate of 3 cubic metres of smoke passing through 1 metre of door edge per hour.
In essence, all intumescents do the same job, but not necessarily in the same way! You’ll need to know which specifications you require; consult our technical team to discuss this area in depth.
Intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescent is predominately used in passive fire protection although a product of any material which expands under the single introduction of heat may be called intumescent.
Intumescent materials though diverse in their chemistry, have the common feature which their name suggests; they will increase in volume by many times when subjected to high temperature. They can be built into fire doors without affecting the normal operation of the door and will only be activated in a fire.
