  • Intumescent seals are a practical,

    well-established method of achieving

    Fire Resistance in designated Fire

    Doors. Heat from a fire causes the

    intumescent material to foam and

    swell, thus filling the gap between the

    door and frame and preventing the

    flow of hot gases and smoke.

    However, not all such seals

    are equal, and as

    concern over

    litigation grows, the

    thoughtful specifier must

    examine all the options to ensure

    that the seal chosen for each project

    really is the most appropriate. As the

    recognised leader in intumescent

    seal technology, Sealmaster offers

    products of proven performance

    and demonstrable cost-effectiveness,

    which can be specified with absolute

    confidence.

    FIRE PERFORMANCE

    Sealmaster manufactures intumescent

    fire and smoke seals which are

    compatible with all types of

    fire-resisting door assemblies.

    Although the principal seals are

    intended for 30 or 60 minute rated

    doors, their design and performance

    characteristics indicate far longer

    endurance potential.

    AUTHORITY

    Sealmaster intumescent fire and

    smoke seals comply with all relevant

    British Standards, and conform to the

    requirements of the Building

    Regulations.

    ALUMINIUM HOLDER

    The heat-treated aluminium holder

    is attractive in appearance, easy to

    install, and retains the intumescent

    material securely and correctly

    positioned in the rebate but without

    weakening either the frame or

    door. Robust and durable in use,

    it offers excellent vandal and

    damage-resistance, plus good heat

    conductivity to assist early

    intumescence.

    THE INTUMESCENT COMPOUND

    Sealmasters specially-formulated

    intumescent material is based on

    mono-ammonium phosphate, and

    is compounded to resist degrada-

    tion by moisture or carbon dioxide.

    When triggered by heat it produces

    a low-pressure, high volume foam.

    A high-pressure exfoliated graphite

    foam is combined with Sealmasters

    traditional material to produce the

    unique Sealmaster Ultima seal, giving

    the benefits of high expansion with

    high pressure to restrict leaf

    movement in a fire.

    ELASTOMERIC BLADE SEAL

    The flexible and easy-to-replace

    flame-retarding elastomeric blade

    seal, acts as a draught seal in normal

  • use and prevents the passage of hot

    or cold smoke, noxious gases and

    flames during fire, thereby keeping

    escape routes open.

    THE INTUMESCENT EFFECT

    Although the intumescent

    material remains hard under normal

    conditions, it intumesces rapidly at

    approximately 140C, and achieves

    a 40-fold volume expansion ratio. All

    seals contain sufficient intumescent

    material to ensure that the designed

    integrity ratings of both 30 and 60

    minutes are achieved with

    comfortable margins.

  • SEALMASTER SYSTEMSHAVE NO EQUAL

    EASY TO INSTALL

    The aluminium holder is easily fitted

    into rebates, and, unlike some glued

    or friction-held plastic holders, is

    firmly pinned in place to resist

    accidental or intentional pull-out.

    ATTRACTIVE APPEARANCE

    The holders can be anodised or

    powder-coated in a range of colours

    to match or complement fittings,

    furniture or other materials in both

    new-build and refurbishment

    projects. Unlike some cheaper plastic

    sections, they do not suffer from

    cracking or bending which can result

    in poor appearance and inferior

    performance.

    VANDAL & DAMAGE RESISTANCE

    The holders are designed to with-

    stand considerable rough treatment,

    yet remain in good condition. Special

    features help protect the intumescent

    material from damage by vandals.

    MAINTENANCE-FREE

    To retain their performance, many

    other seals are coated with epoxy

    resin which must be repaired if dam-

    aged - such repairs are rarely carried

    out in practice - posing a threat to

    fire-performance. Sealmaster seals

    need no such coating, and on-site

    treatment is therefore avoided.

    EXCELLENT HEAT CONDUCTIVITY

    ASSISTS EARLY INTUMESCENCE

    The excellent heat conductivity of the

    aluminium holder assists in the early

    activation of the intumescent foam at

    temperatures as low as 140C.

    DOORS CAN BE EASILY UPGRADED

    Existing doors can often be upgrad-

    ed, in consultation with the local Fire

    Prevention Officer, simply by fitting

    Sealmaster intumescent fire and

    smoke seals into grooves cut into the

    sides and head of the door.

    N.B. Sealmaster intumescent fire and smoke seals are designed to cope with future legislation for hot smoke control, an important factor when dealing with the future upgrading of existing doorsets.

    LOW-PRESSURE FOAM WONT

    WARP OR PUSH OPEN DOORS

    Unlike many other seals, the intu-

    mescent material in Sealmaster seals

    does not expand forcefully

    enough to open doors, Furthermore,

    if doors begin to warp, the foam

    reservoir is more than adequate to

    re-seal the joint. Alternatively, Seal-

    master Ultima high-pressure graphite

    seals can restrict movement of a

    door leaf where desirable.

  • can lead to smoke passing the seal

    before the intumescent is activated.

    N.B. The advantages of intumescent seals have been recognised in Buildings Regulations approved document B: Fire Spread. This document identifies Smoke Control Doors with the suffix S and requires them to be fitted with a flexible seal. Firedoors without cold smoke control are identified by the prefix FD.

    DURABLE SMOKE SEALS ARE

    EASY TO REPLACE

    Sealmaster smoke seals can easily be

    replaced if the frame gap expands

    or contracts due to atmospheric

    effects on the timber. Other seals

    cannot always be replaced, neces-

    sitating an expensive and disruptive

    door upgrade to restore integrity.

    Sealmaster seals are very resistant to

    mechanical wear and degradation, so

    when properly fitted a life in excess

    of 20 years can be expected.

    PROVEN LONGEVITY IN USE

    Sealmaster seals have been removed

    periodically from Wembley

    Conference Centre and fire tested

    DOOR STILL FUNCTIONS

    The soft foam of a Sealmaster seal

    allows doors to be opened and

    does not inhibit attempts to clear an

    escape route or tackle a blaze. Yet

    the ample reserves of intumescent

    material will effectively re-seal the

    joint if the door is closed again - an

    extra safety measure not provided

    by some other seals.

    CLOSES EVEN BIG GAPS

    Doors are not always installed by

    craftsmen joiners, and

    clearances may vary

    considerably from the

    stipulated 3mm + 1mm. With suf-

    ficient intumescent to close gaps of

    up to 6mm, Sealmaster seals main-

    tain integrity without compromising

    Building Regulations.

    RESISTS BOTH HOT AND

    COLD SMOKE

    Sealmaster smoke seals are made

    from vulcanised rubber so they can

    withstand hot, as well as cold smoke

    - something thermoplastic blades or

    pile cannot claim. Likewise, they do

    not suffer from the premature heat

    degradation and breakdown which

    by TRADA and have always achieved

    a fire-resistance rating well in excess

    of the required sixty minutes.

    In the most recent test, Sealmaster

    intumescent seals taken out of

    service after 22 years achieved over

    70 minutes fire resistance in an

    FD60S fire door.

    RESISTS ENVIRONMENTAL ATTACK

    Sealmaster seals have demonstrated

    proved resistance to CO2 and moisture,

    both in independently run long-term

    exposure test programmes and in
