Frequent asked questions
On which side do the perforations
The perforations always go on the side with the largest air
For example, if the panel is screwed directly to the studs, the
perforations should face the wool; if the panel is screwed to a
solid surface (cement, gypsum board), the perforations should face
On which side of the wall should
SONOpan be installed?
It is best to install SONOpan in the room where the noise
originates to prevent it from travelling outside the room. However,
if this is not possible, you can install it inside the room that
you want to prevent the sound from penetrating.
Is it necessary to fill the wall with
wool or cellulose before installing SONOpan?
It is best to fill the wall space with wool or cellulose to avoid
having a resonance chamber in the wall.
Are wood strips as effective as
No, because resilient channels absorb vibrations and separate the
gypsum screws from the stud structure. Furthermore, wood is a major
What type of sound does SONOpan block
when installed on the ceiling?
SONOpan prevents airborne sounds (TV, music, voices, etc.) from
travelling from the lower room to the upper room and vice
Can recessed lighting be installed in

leaks or holes there are, the more sound can escape. Furthermore, a
fire-resistant enclosure must be installed.
Does the risk of fire increase with
The manufacturer's instructions must be followed and metal boxes
must be used to retain the heat produced by the lighting.
Is SONOpan fire
We make a product like SONOpan called SONOsecur that is treated for
fire resistance. It has the same acoustical properties as SONOpan
in addition to being fire resistant.
Why must 5/8'' Type X gypsum board be
used instead of 1/2''?
The 5/8'' Type X gypsum board has a much higher density than 1/2''
standard gypsum board, which helps reduce low-pitched and/or
Can SONOpan be placed directly on the
wall without being covered with gypsum board?
Yes, but the result will not be the same. When SONOpan is used
inside a wall, it creates a barrier to keep the sound inside the
room. However, when SONOpan is installed directly on a wall, it
absorbs sound reverberation (echo) in that room. Always cover
SONOpan with fabric in this type of application to avoid having
green dust on the furniture in the treated room.
