Acoustic and ball-impact resistant profiles
For individual and visually exceptional design solutions, Aluform perforated sheets can preferentially be used for interior decoration or exterior design.
PRODUCTS
Individually design facades and rooms with light, transparency and airiness.
With this in mind, our standard program comprises a broad selection of profile variants. In addition to Aluform corrugated profiles, trapezoidal profiles and the Siding wall panels, also special roof profiles like ALUDECK and ALUFALZ can be processed as perforated sheet profiles. With regard to the interplay of room, colouring, and profile design, perforated aluminium profiles offer a creative spectrum for an innovative architectural design.
Aluform sinusoidal profile 55/177
Aluform trapezoidal profile 29/124
Aluform trapezoidal profile 45/150
Technical peculiarities:
- For technological reasons, the longitudinal edges of the profiles are not perforated on a narrow strip.
- The trapezoidal profile 29/124 of the sheet thickness 0.5mm in H 16 /46 can additionally be manufactured with a strip perforation in the wide chord.
- Siding profiles are available with the hole pattern Rv 2 – 3.5 and Rv 3 – 5
- The aluminium profiles ALUDECK and ALUFALZ are also available as perforated version. In case of both profiles, only the bottom will be perforated.
Aluminium profiles for optimal room acoustics and ball-impact resistant interior panelling
Aluminium profiles with acoustic fleece are ensuring a good sound
The Aluform acoustic fleece improves the acoustics of rooms via the absorption of sound waves. It is glued onto the rear side of the different perforated aluminium profiles in order to optimise the sound absorption of a ceiling system. The absorp- tion degree alpha indicates how high the percentage of the absorbed sound waves is.
This degree depends on the distance between the perforated panels and the solid ceiling, as well as on the hole percentage of the perforation. The Aluform acoustic fleece has been examined with respect to fire protection properties accor- ding to DIN 4102 and has been allocated to class B 2. In connection with the corrugated profile 18/76, the Aluform acoustic fleece has been subjected to a testing of the degree of sound absorption according to DIN EN ISO 354 and has been allocated to the sound absorption classes D and C.
