Seven Levels of Sound Control

Maxxon Underlayment With...

Acousti-Mat II is the industry standard for superior sound control

Enkasonic provides superior sound control

Acousti-Mat 3 offers superior sound control in construction

Acousti-Mat I

The Industry Standard

The Original Sound Control Mat

For Superior Sound Control

Corrugated Steel Deck

■ Low 3/16" profile.

■ Over 100 UL fire designs.

■ Economical choice needing only
3/4" Maxxon underlayment pour depth.

■ Meets IBC sound requirements with
both UL fire ratings and sound tested assemblies.

■ Increases IIC level up to 10 points over wood
frame, and up to 20 points over concrete.

■ Increases STC rating 2-4 points compared
to a 3/4" Maxxon Underlayment/wood frame
system, and 4-12 points when compared to a
bare wood frame system.

■ 40% pre-consumer recycled content

■ Creates sound-rated floors with high IIC and
STC levels required by ICBO, UBC, and FHA for
luxury developments.

■ Durable and proven solution – the only mat
tested after 10 years of use. (Enkasonic retained
97% of original thickness, was as pliable as a
new roll, and performed equally to a newly
manufactured roll.)

■ Increases IIC level up to 15 points over wood
frame, and up to 20 points over concrete.

■ Increases STC rating 6-15 points over bare
wood frame system.

F-IIC (Field Impact Insulation Class) sound tests were performed in accordance with ASTM E 1007 and E 989. F-STC (Field Sound Transmission Class) sound tests were performed in accordance with ASTM E 336 and E 413.
Actual tests above, plus additional tests are available upon request. Acousti-Mat/Enkasonic is but one component of an effective sound control system. No sound control system is better than its weakest component.
Care must be taken in the installation of components of construction to assure the ultimate designed acoustical performance.
