Topakustik Topperfo acoustic systems

 

(Sound absorptive) Acoustic perforated panel systems, by Topakustik, used for ceilings, walls, cabinet fronts or room dividers.

 

Description

 

Topakustik Topperfo systems are sound absorbing (micro-)perforated acoustic systems by the Swiss company Topakustik.

They include panels or planks with circular or slotted perforations (see Perforations below for the different types of perforations) for wall systems, ceiling systems, room dividers or also cabinet fronts and their configuration is usually as follows:

  • air cavity of variable height (from 30 mm to 413 mm)
  • 30 mm mineral or 40 mm rock wool in the cavity
  • acoustic fleece (SP 60 laminated)
  • 16-17 mm Topakustik Topperfo plank or panel

Description of Topakustik Topperfo acoustic systems

The range available for Topakustik Topperfo acoustic systems includes (see Perforations below for more details about the different types of perforations):

  • Topperfo-Micro with micro-perforations of 0.3 or 0.5 mm diameter
  • Topperfo-Clou with perforations of 1.2 mm or 2 mm diameter
  • Topperfo-T with perforations of 3, 4 or 5 mm diameter
  • Topperfo-M with perforations of 6, 8 or 10 mm diameter

Configurations of Topakustik Topperfo acoustic perforated systems

Topakustik Topperfo panels and planks are available with various perforation sizes & designs and core panels.

Note:

The difference between Topakustik Topperfo planks and panels are:

    • The planks have tongue and groove connections, so that the joints between the planks are not visible (they also allow flexible and simple assembly).

    • The panels are used for wall systems, removeable ceilings, cabinet fronts and dividers (with visible joints).

Perforation types

Different types of perforations are available for Topakustik Topperfo panels and planks.

  • Micro Perforations with micro-perforations of 0.3 mm or 0.5 mm diameter for the finish/front layer, nearly invisible but sound absorptive, and larger perforations for the back layer.

Core panels

TopakustikTopperfo planks and panels are either 16 mm or 17 mm thick.

Medium Density Fibreboard (MDF) is mostly used to make the core panels. However, other materials offer better fire, impact and moisture resistances. See Materials used in Topakustik systems below for more information.

 

Sound absorption characteristics of Topakustik Topperfo acoustic perforated systems

Topakustik Topperfo acoustic systems achieve sound absorption performances ranging from Class E up to Class A depending on the following:

  • the perforation type
  • the size and the quantity of the perforations
  • the size of the cavity behind
  • the type and the amount of sound absorption in the cavity behind

Some interesting sound absorption features are as follows:

  • the denser the micro perforations, the higher the sound absorption at high frequencies (i.e. above 1000 Hz). At low and mid frequencies, the sound absorption remains similar.

  • the larger the holes, the higher the sound absorption at mid and high frequencies (i.e. above 500 Hz). At low  frequencies, the sound absorption remains similar.

Materials used in Topakustik Topperfo acoustic perforated systems

Most Topakustic Topperfo panels and planks are made with Medium Density Fibreboard (MDF).

But other materials are also used such as:

  • RESAP® :  non-flammable material made with natural gypsum and recycled cellulose fibres (see Fire resistance below)
  • Flakeboard OSB
  • ‘standard’ plywood
  • Particle board
  • Blockboard
  • Cement
  • Hardwood (silver fir) for ARIA-Pure systems
  • MDF and hardwood (spruce or white fir) for ARIA-Plus systems
  • 3-layer plywood (silver fir)

Finishes and shapes of Topakustik Topperfo acoustic perforated systems

 

Finishes

For Topakustik Topperfo acoustic systems, three different types of finishes are available. They include:

  • Wood veneer finish (Knotty Oak, Oak Europe, Nut Tree/Walnut, Maple US, Cheery US, Birch, Maple Europe, Ash,  etc.)
  • Painted finish (any color is available).

For more information about finishes, get in touch with Topakustik or your local supplier (check Who supplies Topakustik systems? below).

Shapes

Most Topakustik Topperfo planks and panels are flat, but they can also be bent to create curved surfaces.

Other bespoke shapes are also available.

 

Other physical characteristics of Topakustik Topperfo acoustic perforated systems

 

Fire Resistance

For Topakustik Topperfo acoustic perforated systems, the fire resistance varies with:

  • the material used for the core panel.
  • the application (or not) of fire retardant agents.

See examples of fire resistances achieved for different materials used for the core panel:

  • RESAP®: A1 (EN A1-s1, d0 ; CH RF 1)
  • Cement:  A2 (EN A2-s1, d0 ; CH RF 1)
  • Forex: B1 (EN B-s2, d0 ; CH RF 2)
  • Plywood, flakeboard OSB, particle board or blockboard: B2 (EN C-s2, d0 ; CH RF 3)

Some interesting fire ratings to also note for different types of raw MDF panels used for the core panels:

  • B2 (EN C-s2, d0 ; CH RF 3) for
    • MDF E1 moisture resistant V313
    • MDF E0-B2 with no added formaldehyde
    • MDF E0-B2 FSC certified
    • MDF E1-B2 Standard
  • B1 (EN B-s2, d0 ; CH RF 2) for
    • MDF E0-B1 with fire retardant
    • MDF E1-B1 with fire retardant

Humidity resistance

The humidity resistance of Topakustik Topperfo acoustic perforated systems varies depending on the material used for the core panels.

For examples, systems which core panels are made with forex or cement can be installed in humid environments.

For more information about humidity resistance, get in touch with Topakustik or your local supplier (check Who supplies Topakustik systems? below).

Impact resistance

Most Topakustik Topperfo acoustic perforated systems are impact resistant.

Therefore, you can install them in places, like sports halls, where high impacts (from balls for examples) occur frequently.

 

Sustainability of Topakustik Topperfo acoustic perforated systems

Some Topakustik Topperfo acoustic perforated systems are made with raw MDF that don’t use any formaldehyde to bond the fibres together.

Some of the raw MDF is also FSC certified, which ensures that the timber used to make the fibres is sustainably sourced.
