The Best Soundproofing is achieved by combining materials

Reduce Resonance

Insulation – Resonance Reduction

Insulation stops resonance in an empty cavity and helps capture certain frequencies. The human ear cannot hear the difference between specialty, fiberglass, wool or cellulose type insulation so it is our recommendation to simply use the appropriate size insulation for the cavity. Spray foam and polystyrene insulations are not recommended for sound attenuation.

Absorb Sound

SONOpan – Absorption

Our panels are dual function, they create a solid barrier to stop sound while also absorbing a wide range of sound frequencies, including low bass. Our Noise STOP Technology is the key to this, SONOpan has over 17,000 impressions in both sides of the panel resulting in a varying density throughout. When it comes to soundproofing, each frequency range has a corresponding sound wave where the peaks and valleys of that range are a certain size. The peaks and valleys in SONOpan are what make it extremely effective at soundproofing.

Stop Vibrational Noises

Decoupling (For extreme soundproofing only)

Decoupling is the most common item to be left out of an assembly for good reason, since it is not usually neessary.

If you require extreme soundproofing there are several ways to decouple a wall or ceiling. Essentially what decoupling does is break the connection between two building materials. This reduces the transmission of sound vibrations from one material to the other. Decoupling is not always a necessary addition to soundproofing but it is quite effective when heavy vibrational frequencies are present.

Options include

  • Resilient Channel
  • Isolation Clips with Hat Channel
  • 2X4 studs staggered on 2X6 top and bottom plate, weave insulation
  • double 2×4 wall assembly, staggered studs with 1″ gap between insulated walls

Block Noise With Mass

Mass – 5/8″ Drywall

Mass is an important element in soundproofing, like the other 4 elements there is no substitute for mass. There are several options when it comes to mass but the simplest is drywall. 5/8″ thick drywall is not only thicker than 1/2″ but also has a denser core which is superior for soundproofing applications. In extreme soundproofing situations up to 2 sheets of 5/8″ drywall can be used on each side of the wall or on the ceiling. Don’t let that intimidate you though! Many situations will still do just fine with a single sheet of 1/2″ drywall.

Working With SONOpan

STC Rated Assemblies

SONOpan - STC 27

SONOpan panels alone have an STC rating of 27

    • Panel dimensions 4 foot x 8 foot 3/4 inch thick
    • Made from 100% recycled wood, natural binders and food grade colour, they’re easy to work with and don’t contain any harsh glues or chemicals
    • Install SONOpan OVER the joists or studs on any wall or ceiling
    • SONOpan can be installed behind drywall in new construction or sandwiched between the existing and a new drywall sheet of drywall in retrofit situations
