Mann McGowan has been at
the forefront of intumescent
seal technology for over 30
years. Add to that unrivalled
experience and expertise,
dedicated personnel, wide-
ranging technical support and
true worldwide capability, and
it is easy to see why Mann
McGowan is synonymous with
Sealing Solutions at their best.
By devoting considerable
resources to on-going research
and development, the company
constantly improves and extends
its product range, introducing
innovative seal solutions to an
increasingly wide diversity of
applications.
Since its foundation, Mann
McGowan has been continuously
investing in the development of
new products and technologies
to meet the ever-growing
demand for improved fire, cold
smoke, acoustic, weather and
draft sealing, and the challenges
presented to them by ever
changing building techniques and
materials.
Pioneering intumescent seal
encapsulation in 1977, Mann
McGowan set the standards that
are still in use in the building and
construction industries today.
This key technology underpins
the company’s current and future
products.
Every Mann McGowan product
is subject to rigorous quality
control throughout its design and
manufacture. Independent third-
party evaluation and testing to a
range of standards is paramount
in showing compliance to
relevant codes of practice.
Today, Mann McGowan has an
unrivalled global reputation for its
advanced sealing solutions, with
installations in such prestigious
locations as Canary Wharf, The
Victoria and Albert Museum,
Twickenham Rugby Football
Stadium, The Royal Albert Hall,
The Millennium Stadium and as
far afield as Hong Kong Airport
and The Hilton Hotel – Cairo.

Noise pollution is proving
to be an increasing problem
in today’s society and is
recognised as a major
environmental problem
affecting millions of people
around the world. And in
today’s environmentally
sensitive times, using the
most energy efficient methods
available to maintain a
controlled temperature is
equally paramount.
Mann McGowan has enhanced
its highly successful Enviroseal®
range to include Acoustic
Sealing Solutions, offering
complete acoustic, smoke, dust
and ambient weather seals.
Importantly, these seals can be
used in conjunction with Mann
McGowan’s intumescent seals to
provide complete protection.
Acoustic seals help isolate rooms
from airborne noise generated
within a building, such as plant
and machinery, recording studios,
cinemas and interconnected hotel
rooms. They also help isolate
buildings from external traffic
noise from roads, railways and
airports.
Installing seals in the gaps around
a door is the primary method of
reducing sound passing into or
out of a room or building.
Mann McGowan’s Enviroseal®
Acoustic Sealing Solutions include
a highly engineered Acoustic
Threshold Seal as well as a range
of uncomplicated retrofit seals for
door heads and jambs. Together,
they offer an excellent barrier
to airborne sound making the
acoustic attenuation provided by
a door and its frame equivalent to
the wall into which it is installed.
Effective sealing also offers
protection against smoke and
fire, insects and the elements.
Used in combination, Enviroseal®
seals cut heat loss and eliminate
cold draughts - measurably
reducing energy usage – and
prevent the ingress of smoke,
airborne dust and insects.
Now, the Mann McGowan
Enviroseal® range enables
you to meet ever-changing
Building Regulations, the current
requirements of Approved
Document E and Building Bulletin
93, and take into consideration
the Noise Act 1996.

Flexifin® Fire, Acoustic and Smoke seal
A unique innovation in door seal design, Flexifin combines
excellent acoustic sealing properties against the spread of
noise as well as cold smoke and draughts. Flexifin seals can
be combined in a rigid PVC holder with Pyrostrip 100 and 500
intumescent materials to add superb resistance to fire spread.
Acoustic performance test
Flexifin can be
used in combination with a
variety of other seals to provide
complete protection. Flexifin rigid
PVC holders are available in a
variety of colours. Flexifin blades
are manufactured from black
thermoplastic.

SpeechBecause noise is not restricted to
100Hz - 4,000Hz, Mann McGowan
tests its Enviroseal® range to
10KHz
The Enviroseal® Acoustic Seals
range has been tested by
UKAS-accredited (No: 0444)
Sound Research Laboratory
in accordance with BS EN ISO
140-3:1995 - and beyond.
The results were presented in
Report C/05/5L/3372/1A.
Test set-up
Airborne sound transmission is
determined from the difference in
sound pressure measured across
a test sample installed between
two reverberant rooms. To ensure
good acoustic isolation, resilient
mountings and seals are used to
isolate the 50m3 receiving room
from the surrounding structure.
The adjoining - source - room has
a volume of 55m3.
An electronic generator, power
amplifier and loudspeaker are
used in the source room to
produce broad band noise. The
resulting sound pressure levels are
sampled in both rooms using a
microphone connected to a real-
time analyser. The sound pressure
level difference [D] across the test
sample is calculated from:
D = LS - LR
where LS is the equivalent sound
pressure difference in the source
room, LR in the receiving room.
The Sound Reduction Index [R]
(USA - Sound Transmission Loss)
is the decibel reduction in sound
energy randomly incident on the
test sample:
where S is the area of the sample
and A the total absorption in the
receiving room.
The Sound Reduction Index is
an expression of a particular
test subject, its mass, thickness,
sealing method, etc., under
laboratory conditions; the actual
sound reduction index achieved
in a particular installation will be
different.

Acoustic performance test
BS EN ISO 140-3 specifies acoustic testing between frequencies
100Hz and 3,150Hz, US ASTM between 125Hz to 4,000Hz. But
the top note of a piano is 4,186Hz and the frequency content of
speech lies between 125 and 8,000Hz. It is for such reasons that
Mann McGowan Enviroseals® are tested to 10,000Hz, well beyond

Making the sound choice
We have provided the table below to help you select the right seals combination for your
application. Information is presented as combinations of Enviroseal® seals that provide
a good balance between acoustic performance and other functions, including the DD1
Acoustic Threshold Seal which is essential to maximising performance and meeting the
requirements of Approved Document E.
For maximum performance, Mann McGowan’s recommendation has been highlighted in red.
All Enviroseal® acoustic seals are designed for commercial use, including heavy-duty.
