Acoustiblok: sound insulation product
for boat engines, generators, and other marine applications.
| Finally a sound
deadening material that is waterproof, simple to install
and works better than lead.
Noise from engine rooms, generators and structure vibrations
can prevent hearing normal conversations. Not only is
the loud noise annoying, but it lessens the enjoyment
of your outing. Acoustiblok® can
effectively treat many sources of marine noise.

A happy yacht builder writes:
Danube
Marine is a young company specialized in the completion of luxury motor
yachts, from A to Z including Superyachts. When the 102 Ft long hull that will one day become
the fast and luxurious Yacht “Romantica” was delivered for completion on their shore of the
Danube, they encountered the problem of noise control.
Immediately under the main deck with the beautiful lounging area, two huge MTU
turbocharged engines with 2250 HP each will be roaring, along with power plants for
electrics, airco equipment and water makers! Having all those noise sources only two inches
away from the dining table, they were desperate for solutions.
Acoustical consultant Willem Kraan strongly advised the use of Acoustiblok® as the main
product for all sound abatement aboard. Acoustiblok® turned out to be an easy to apply
product that has proven to be excellent in all conditions, also in a harsh salt water
environment. Danube says they are very pleased by the way Acoustiblok® turned out to be a
high performance, versatile and easy to install sound isolator! Although the “Romantica”
has not been launched yet, test with noise generators has proven the isolation is very
satisfactory!

The Fugro Explorer's common room is located directly above the engine room,
which creates the kind of noise problem Acoustiblok is uniquely suited to
resolve. Acoustiblok was installed over Acoustipad on the deck of the common room,
and carpet was laid on top it. The contractor who did the installation tells us,
"The noise problem was solved - the customer is very happy with the results of
installing Acoustiblok."

sound insulation
Engine noise is something most boat owners take
for granted, but Acoustiblok is the easy way to
change all that.
Looking like a thin sheet of rubber like fabric,
this waterproof material is resistant to oil and
grease, extremely flexible, easily cut and laid
in place around corners, and can be stapled or
glued into place.
Once in place, the company says it reduces sound
transmission by 26db. What makes that impressive
is the
fact that lead can reduce |
sound
transmission by a maximum of only 20db.
Made with no lead or asbestos materials, Acoustiblok
is environmentally safe and will not compress
when installed beneath carpet. It can be installed
anywhere sound levels are a concern, including
along aft bulkheads, salon flooring, hatches or
the interior of the engine room. Water
proof, UV resistant and surpassing UL94 burn tests...

Acoustiblok may well be one of the easiest ways to dampen
noise levels aboard a boat. Whether your vessel is an
express cruiser or a passage making trawler, adding
Acoustiblok insulation can make it quieter and thus
a more pleasant place to be. Southern Boating. |

Sound Blocker Tested
Wouldn’t
it be nice if powerboats were as silent as
sailboats? It might seem strange at first,
but we’d quickly get used to conversing
at normal levels. All we can do, however,
is make our boats as quiet as possible. I
recently witnessed its effectiveness in a
Hatteras 42 Convertible with 440-hp Yanmar
diesels that I spend a good deal of time every
summer.
One feature that recommended Acoustiblok,
whose motto is “When what you don’t
hear counts,” to the owner was its new
light gray color (it’s also available
in black). Another was its thickness, or rather
thinness, of only .11”.
Acoustiblok is a flexible, extremely dense,
UV- and fire-resistant vinyl material that
sheds oil, grease and water and can be easily
cut and easily attached to virtually any
surface
with screws, nails, staples or glue. It contains
no lead or asbestos, yet it exceeds lead’s
sound-deadening capability. In an engine
room,
it can be installed on the sidewalls and
bulkheads as well as overhead. Beneath
cockpits, it
can be installed under the deck as well as
on sidewalls and bulkheads, and it can
be
laid under the carpet (it won’t compress).We
laid it under the carpet of the Hatteras’
salon, where it acted as padding, making
the carpet much more comfortable to stretch
out
on. |
As can be the case,
it was impractical to install Acoustiblok on
the outer walls or on the bulkheads of the salon,
but we put it in the engine room directly below
the salon-just on the sidewalls and headliner
and on the undersides of the hatches. (The bulkheads
had too much machinery on them for us to tackle
installing it there.)
At
idle speed, a reading of 74 decibels in the
salon without Acoustiblok dropped to 72 with
it. At 1500 rpm, there was a three-decibel
drop,
which was the case at 2500 and 3000 rpm as
well. At WOT (3400 rpm), the difference was
four decibels
(86 vs. 82).
Acoustiblok comes in 4’6”-wide
rolls, 30 feet and 60 feet in length. It costs
about
$2.50 per square foot (psf). The standard material,
which we used, is 16-ounce Acoustiblok, which
weighs one pound psf. Two-pound-psf Acoustiblok
is also available. In addition to being heavier,
it is thicker and not as easy to work with,
but it’s said to be almost twice as
effective and costs only a bit more.

* The words "soundproofing" or "sound proofing" do not mean
100% sound elimination, which is impossible. Use the
supplied STC, IIC, and NRC ratings from independent lab test reports
to estimate the results of installing Acoustiblok® products.
