HOFA Wall Sail
Absorber made of HOFA PureAkust®
HOFA Wall Sail
The HOFA Wall Sail is an absorber which reduces disturbing sound reflections on walls and minimizes the reverberation time. The highly effective absorption quality is achieved through our innovative HOFA PureAkust®. The specially developed material ensures a pleasant living and working environment with high speech intelligibility.
The puristic look makes it possible to use it as a design wall element. The acoustic effectiveness can be significantly increased with the help of the optionally available wall mounting system HOFA PureFix. The magnetic solution offers a variable adjustment of the wall distance between 4,5 and 9 cm. Therefore the HOFA Wall Sail is a suitable solution for demanding control and HiFi rooms.
Exemplary product illustrations
The scope of delivery includes two sawtooth hangers for flush mounting.
Alternatively, choose the innovative HOFA PureFix wall mounting set for installation with a variable wall distance between 4,5 and 9 cm. This solution increases the acoustic effectivness, can compensate uneven walls and is able to redirect reflections through an angled attachment.
The HOFA Wall Sail is the effective & elegant acoustic element for your wall.
Areas of application
A HOFA Wall Sail M in 120 x 120 cm consists of 51 recycled PET bottles
Our absorption material
- Tested for harmful substances and odorless
- Oeko-Tex Standard 100 (highest product class)
- Bacteriostatic and allergy-friendly
- Free of formaldehyde
- Flame retardant B1 according to DIN 4102-1 and EN 13501-1
- CO2-saving production and 100% recyclable
- Health-friendly usage compared to conventional acoustic products made of glass or rock wool
- Sound absorber class A in typical application (according to EN ISO 11654)
- Much higher absorption than standard brand products (up to 55% compared to melamine resin foam and up to 70% compared to knobbed foam of the same thickness)
Despite the low material thickness of 40 mm, which gives the ceiling sail a subtle look, HOFA PureAkust S® offers excellent absorption behavior. With the help of the optionally available HOFA PureFix wall mounting set, the absorption capacity at low frequencies can be significantly increased.
Measurement of sound absorption in-situ according to DIN CEN/TS 1793-5
HOFA PureFix wall mounting set
Like all porous absorbers, the HOFA Wall Sail benefits from optimal positioning at a distance from the wall. The absorber can work best where the sound particle velocity has its maximum. The magnetic telescopic holders of the innovative mounting set make this possible. The wall sail can be attached in no time at all and the distance to the wall can be infinitely adjusted between 4.5 and 9 cm. With this measure, the wall sail achieves the highest sound absorber class and is performant even at lower frequencies.
A horizontal angulation of the wall sail is possible by different settings of the holder. This allows an advantageous deflection of early reflections in the area between the listening point and the loudspeaker.
Thanks to the 3/8“ thread, the absorber can be easily mounted on conventional microphone stands. In this way, every recording situation can be mastered acoustically, even with mobile on-site recordings. The lightweight acoustic elements are practical problem solvers to reduce crosstalk and to control the excitation of the room.
