Design options with acoustic foam

Adding the acoustic foam material Mikropor AS to our product portfolio has succeeded in giving us the ability to offer our customers a true all-rounder in the field of acoustic design – and above all in the field of retrospective acoustic upgrades.

Bargteheide, Germany, Emil-Nolde School

Measurement of reverberation time, speech intelligibility and sound propagation.

To integrate hearing-impaired children in mainstream education a classroom was upgraded to improve the acoustics. The product MIKROPOR AS VE B1 was installed. Sound measurements in the upgraded and a comparative room were carried out by Mr CARSTEN RUHE, Acoustic Consultancy.

Advantages

  • Affixes directly to the ceiling or wall with adhesive
  • No substructure required
  • Installs quickly and cleanly, including in occupied properties
  • Retrospective improvements to the acoustics possible, without dirt and noise from machinery
  • Also suitable for low installation heights
  • Design freedom thanks to free-form design and colour schemes
  • Economic solution thanks to low installation costs
  • Also available as an acoustical cloud

MIKROPOR® AS and MIKROPOR® AS VE made of melamine resin foam (Basotect®)

The wide variety of available formats through to customized free-forms and 3D bodies, different thicknesses and surfaces mean it is possible to individually design acoustic concepts and adapt the product to fulfil specific requirements. It goes without saying that in addition to ceiling systems, acoustic partial areas and ceiling cloud solutions we also offer wall absorbers.

This product achieves impressive results in particular when making improvements to the acoustic environment; thanks to its low weight of just 600 g/m² (40 mm thickness) it can be affixed retrospectively to practically all existing wall and ceiling systems.

The almost unbelievable sound absorption values make this product an ideal building material to optimize the acoustics in a room.

This product is ideally suited to optimize the acoustic environment, in particular in rented properties. Acoustical clouds and wall absorber elements that can be hung up as simply as a picture can be easily taken with you when moving to a different premise or relocated when converting a space.

Material:

Open cell foam made from melamine resin (Basotect®).

Surfaces:

MIKROPOR® AS an open cell foam to form a natural surface, with coloured surface coating on request; also available in special colours as per sample

NOTE:

Different sized pores (cavities) can be created during production of this foam. The thinner the material is cut the more clearly visible these cavities will be. This does not impair the function of the material. Nor can it be accepted as retrospective grounds for complaint.

The number of cavities is within the following tolerances:

  • Size up to 5 mm no limit
  • Size 5-15 mm up to max. 10x per/sqm
  • Size 15-25 mm up to max. 1x per/sqm

Our tolerances for finished parts are:

  • Up to 250 mm +/- 3 mm
  • Over 250 mm up to 1000 mm+/- 5 mm
  • Over 1000 mm up to 2000 mm-/+ 10 mm

MIKROPOR® AS VE

Acoustic fleece with matt, smooth
and non-directional surface. The
raw material is covered with fleece;
in other words, there are no cavities visible.

Coloured surface coating available if desired
Also available in special colours as per sample.

Edge configuration:

MIKROPOR® AS
All sides chamfered or cut
straight / coated in the same colour tone as the surface

MIKROPOR® AS VE
All sides chamfered or cut straight
All sides covered with edge tape /
Coated in same colour tone as the surface
Panel thickness:
Standard approx. 40 mm
Custom thickness on request

Dimensions:

MIKROPOR® AS
1250 x 625 mm, 625 x 625 mm

Further dimensions and customize free-forms possible on request

MIKROPOR® AS VE
2400 x 1200 mm, 1200 x 1200 mm, max. 2450 x 1250 mm

Other dimensions possible on request.

Building material class:

MIKROPOR® AS
B1 (flame resistant)

MIKROPOR® AS VE
Core panel B1 (flame resistant)
with fleece finish

 

Weight per unit area:
Approx. 600 gr/m² (for 40 mm panel thickness)

Care / refurbishing:
It is possible to clean localized
soiling using a damp
synthetic sponge or
brush. Vacuum clean with vacuum cleaner
and brush attachment.
Refurbishable by spraying
with Wilhelmi acoustic paint (WAF-R),
without any loss of sound absorption properties.

Sound absorption:
The open pore surface of
MIKROPOR® AS melamine resin foam (Basotect®) guarantees
sound waves are not reflected as reverberation, but
are able to penetrate into the cell structure without hindrance. The sound energy is reduced inside the cell structure.
Consequently, MIKROPOR® AS melamine resin foam (Basotect®) has an excellent sound absorption capacity.
In environments with deep frequencies it is possible, for example, to achieve acoustic improvements
with additional heavy layers.
