HOW BASWAphon WORKS
High frequency sound absorption is accomplished by
allowing sound wave energy to pass through the micro pores
in the finished surface, thereafter, dissipating it into heat
energy in the mineral wool.
Low frequency sound absorption is accomplished when
sound wave energy hits the mass of mineral particles on
the finished surface, causing the finished “skin” to vibrate
in a diaphragmatic action against the mineral wool backing,
creating a “spring” action. Again, this transforms and dissipates sound energy into heat energy.
BASWAphon SYSTEMS AND NRC RATINGS
The BASWAphon Seamless Acoustical Finish System is
available in 3 system thicknesses.
| NRC Ratings |
30mm – 0.80
40mm – 0.85
70mm – 0.95 |
Coefficient testing is calculated with the BASWAphon
systems applied to 5/8” gypsum board, following ASTM
C423 Sound Absorption Test guidelines. Certified Test Data
reflects actual installation conditions and is supplied by
independent third party.

INSTALLING THE BASWAphon SYSTEM
1. Pre-Sanded Rigid Supporting Panels with beveled
edges, are cut to size on site with a utility knife and
adhered with a plaster based adhesive to a stable
substrate, such as taped drywall.
2. BASWAphon Pre-Fill is troweled into the “V” groove
seams formed by the beveled edges of the panels.
3. Sand the panels and Pre-Filled seams.
4. BASWAphon Base Coat is spray applied, gauged,
smoothed with a trowel and allowed to dry.
5. Sand the Base Coat.
6. Classic Top Coat, Frosted or Resilience finish coats
are spray applied, gauged, smoothed with a trowel an
allowed to dry.
BASWA acoustic’s Team has been trained by the Swiss
manufacturer on the proper means to install and guide
other applicators.
CLASS A FIRE RATED
BASWAphon is a Class A fire rated interior finish meeting
all the requirements of UL E-84.

CUSTOM FINISHES
Custom Finish are available upon request. Finishes can
replicate “Old World” plaster aesthetics. FROM MODERN MUSEUMS TO
HISTORICAL RESTORATIONS
Ideal for both new construction and restoration
projects. Since BASWAphon can be applied to
existing historical substrates without damaging
them, it has the ability to enhance the soundscape while preserving the integrity
of the historical architectural elements.
